We also inform that in the case of the remaining network operators, the DGEG does not yet make this service available.
By choosing to purchase measuring equipment - which integrates the meter, communication modem, activated GSM card, power transformers and voltage transformers when necessary - the costs associated with the purchase of these components, as well as the costs of installation, operation, are responsibility, as well as interventions in the equipment or need for replacement. On the other hand, if you choose to purchase the equipment, you should contact E-REDES after completing the installation so that it is possible to schedule a visit of the technical team with the purpose of carrying out a communication test, validation of the operation and sealing of the equipment.
There will be installed a single equipment that will record both the energy consumed as a customer and the energy injected as a producer. The cost of purchasing this equipment is your responsibility.

The costs associated with its installation, operation and future interventions, including possible replacement, will be from E-REDES.

When you opt for the bidirectional equipment acquisition, a cost will be charged on the electricity supply invoice presented to you by your marketer.

Whatever your choice, the producer is responsible for purchasing the total energy counting equipment as well as the associated components.

The costs associated with the purchase of the metering equipment - which includes the meter, modem, GSM communications card with PIN disabled - are the responsibility of the owner of the Production Unit for Self-consumption.
Electricity generation under ordinary regime is the activity of energy production that is not covered by a special legal regime.

These include the electroproductive centers with contracts of maintenance of contractual equilibrium, contracts of purchase of energy or that benefit of incentives to the guarantee of power.

The figure of ordinary regime producer was established by Decree-Law no. 29/2006, of February 15, which establishes the bases of organization and operation of the national electric system, as well as the general bases applicable to the exercise of activities production, transportation, distribution and sale of electricity and the organization of electricity markets.

These production facilities are, as a rule, linked to the national transport network and include the so-called conventional production: thermal power plants and large hydro (> 50 MVA).
Electricity producers in ordinary regime can sell the electricity produced through the following modalities of commercial relationship:

a) Conclusion of bilateral contracts with final customers, with electricity merchants and, if applicable, with the entity responsible for the management of energy acquisition contracts;

b) Participation in organized markets.

Ordinary regime electricity producers may also provide system services, by entering into contracts with the system operator, or by participating in organized markets for this purpose.
The exercise of ordinary electricity production activity is free, subject to obtaining a production license, to be assigned by the licensing entity, at the request of the interested party.

Among the general criteria of the production license allocation decision is the existence of conditions of connection to the public network adequate for the management of its capacity to receive electricity. Information on the existence of reception capacity and the conditions for connection to the network should have been issued less than eight months previously by the network operator to which the applicant intends to connect.

The Directorate-General for Energy and Geology shall exercise the licensing authority's powers to instruct and conduct the procedures for granting, amending, transmitting and terminating the licenses and authorizations envisaged and submitting them to the decision of the member of the government responsible for energy.
The holder of the production license may only start the industrial exploitation of each of the generating groups that make up the electroproducer center after obtaining the respective operating license to be issued by the licensing entity following the inspection.

The operating license defines the conditions to which industrial exploitation is subject and, once granted, will become part of the conditions of the production license of the electroproducing center to which it refers.
Production under special regime is considered to be production activity subject to special legal regimes, such as the production of electricity through cogeneration and endogenous, renewable and non-renewable resources, microproduction, mini-generation and production without power injection in the network , as well as the production of electricity through endogenous, renewable and non-renewable resources.

The following producers are currently considered:

• Hydroelectric plants up to 10 MVA of installed capacity;

• Producers whose sources of energy are renewable, industrial or urban waste;

• Cogeneration producers (heat and electricity);

• Micro-cogeneration;

• Small cogeneration;

• Miniprodutores (revoked, applicable in medium and low tension connected);

• Microproducers (revoked, applicable in low voltage connected);

• Small production unit (applicable in medium and low voltage);

• Production unit for self-consumption (applicable in high, medium and low voltage).
The activity of production of electricity under special regime can be exercised on one of the following remuneration schemes:

The general scheme: electricity produced is sold under ordinary regime production on organized markets or through the conclusion of bilateral contracts with final customers or with electricity traders, including with the market facilitator or any marketer who aggregates the production;

The guaranteed compensation scheme: electricity produced is delivered to the last resort supplier, against payment of the remuneration attributed to the electroproducer center.

Special regime electricity producers may also provide system services by entering into contracts with the system operator or by participating in organized markets under the terms provided for by law.
If your meter does not report readings automatically, our staff will make meter readings on a quarterly basis.
You can report the reading using one of the following methods:
Digital Customer Service (Balcão Digital), available on our website.
E-REDES APP (available for Android and IOS).
Our toll-free number for readings (800 507 507, 24h/day).
Through your electricity supplier.
Readings in normal routing, carried out by readers at the service of E-REDES on a quarterly basis, are free of charge for the Customer.
However, if it is not possible to access the meter for an extended period, E-REDES may carry out an extraordinary reading at a cost to the customer, as defined by the Energy Services Regulator.
This cost is currently 7.15 euros (+ VAT), as defined in the Commercial Relations Regulation (RRC), and will be included in the electricity bill issued by your supplier.
Yes, your electricity supply may be disconnected due to missing meter readings.
Under the applicable legislation, if you do not submit your meter readings or allow a technician access to collect them, your electricity supply may be disconnected.
This will only occur after you have been given prior notice.
The most recent validated reading will be taken.
Request a special meter reading through the Digital Service Portal or the E-REDES Digital App
Go to the Meter Readings menu, available on the Digital Service Portal (Balcão Digital) or in the E-REDES Digital App, select the Schedule a Meter Reading option, and complete the application form.
Please note that a special meter reading is a chargeable servisse.
Follow the steps below. If the meter continues to register consumption while everything is switched off, report the issue.
If you believe your electricity meter is not recording your consumption correctly, follow these steps:
Record the meter readings.
Switch OFF the consumer unit and leave it off for 30 minutes.
Switch the consumer unit back ON and record the new meter readings.
Compare the two sets of readings.

If the readings remain unchanged, it means that the meter did not register any consumption while the electrical installation was disconnected. This indicates that the meter is operating correctly.
If the readings have changed, it means that the meter continued to register consumption even though the electrical installation was switched off. If this is the case, please report the issue through the Contact Us section.

In addition to the name change from EDP Distribuição - Energia, S.A. to E-REDES - Distribuição de Eletricidade, S.A., the new E-REDES brand also has a logo, whose graphic line is marked by the new name of the company in black with yellow in the background. This change in image, which no longer has elements of color or design common to other companies in the EDP universe, also strengthens the identification and uniqueness of the distribution network operator.
EDP Distribuição- Energia, S.A. (EDP Distribuição) was renamed E-REDES - Distribuição de Eletricidade, S.A. (E-REDES) as from January 29, 2021.
E-REDES continues to be the EDP group company that operates the energy distribution networks in mainland Portugal, under a concession regime.
The big challenge is to ensure that everyone is aware of the change so that the new brand gains the notoriety necessary to ensure the operability of the millions of face-to-face interventions we make in the field, from registering meter readings to making new connections. The quick association of the new brand to the distribution network operator will prevent possible refusals of access to our operations or even the use of the old brand for fraudulent practices by third parties to less informed consumers.
The "E" in E-REDES stands for energy, and the word "NETWORKS" translates, in a very clear way, our focus on integrated management of the entire distribution network, capable of ensuring reliability, security, modernity, and sustainability of the national electricity system and safeguarding the interests of consumers, municipalities, and the country.
No. E-REDES is the entity responsible for operating the electricity distribution networks in high, medium and low voltage on the mainland, under a concession from the State and the 278 municipalities and, to this extent, delivers electricity to more than six million delivery points, regardless of the supplier chosen by customers.

To this extent, E-REDES is not allowed to sell electricity, by virtue of the rules that enshrine the separation of activities in the electricity sector, and therefore does not enter into contracts for the sale of electricity. This activity is carried out by the various suppliers existing in the market, with whom the consumer is free to contract his energy.

Specifically: if being an "EDP customer" means that you contract your electricity from one of the EDP Group suppliers - EDP Comercial or SU Eletricidade - then changing the brand of the electricity distributor has nothing to do with this relationship, just as in the case of contracts with all other suppliers outside the Group.
The conditions of the contracts remain unchanged, with only the need to inform the entities with which the Company contracts about the name change.
The change in the Company's name has no impact on the relationship with the Municipalities.
As of January 29, 2021, EDP Distribuição will be renamed E-REDES - Distribuição de Eletricidade, S.A. The new name and brand must therefore be used universally by all stakeholders.
No. The Tax Identification Number and the Legal Entity Identification Number remain the same, as well as all the other identification elements of the company, with only the commercial name of the Company being changed.
No.
The email remains the same, but with a new domain. That is, with the change of the brand, the emails of E-REDES' employees will have the same name, but will end in @e-redes.pt. However, communications sent to the old addresses will be forwarded to the new ones. In case there are other changes in the box names (and not only in the @e-redes.pt domain), communications sent to the old addresses are also forwarded to the new ones.
Yes, the change of brand has no impact on the resolution of the issues being handled. The reference assigned to the request will remain the same.
No. Since the Company has only changed its brand name to E-REDES, it is not necessary to provide the Company with your data again or to make a new registration in the reserved area.
Yes, it is the same Company, with a new name and brand. You can continue to contact the Company and have access to all services through the same Service Points that will now have the reference to E-REDES.
No. The telephone numbers for customer support remain the same, without any changes. You can also continue to contact the Company through the Customer Service Points, which have only undergone image updates. In the digital media, the address has changed to e-redes.pt, but if you access through the previous address you will be forwarded.
No. The change of brand and name has no impact on the structure of the company or on the work developed by our teams. It is the same company, with a new brand. The sense of presence, execution, responsibility, and prompt response remains unchanged.
Yes. The rebranding to E-REDES has no impact on the work developed by our teams, the service provided by the Company, or the relationship with stakeholders.
No.
Following ERSE's approval, the rebranding now takes place in ERSE Instruction no. 4/2020 of August 11, 2020, which set a transitory period until January 31, 2021, for the company to implement the necessary measures to achieve the corporate image.
The Company and its employees already had their own facilities, so the rebranding to E-REDES has no impact on the work developed by the teams, the service provided by the Company, or the relationship with stakeholders.
The Company maintains its commitment to continue being a trusted brand that is close to its consumers, with a quality service that is customer-focused and guided by strong social responsibility.
The Company has an ongoing communication plan that aims to be as comprehensive as possible, taking into account the limitations on cost neutrality, and which aims to enhance all points of contact with the Company, including the website, the APP, the Customer Support telephone lines and the Service Points. To this end, an information initiative is planned for the regional media.
With the rebranding, the e-mails of E-REDES employees will end at @e-redes.pt, the new domain. However, communications sent to the old addresses are forwarded to the new ones.
After the brand change, any technician at the service of E-REDES can be identified through the vest and the respective identification credential. In case of doubt or suspicion that it is not a technician at the company's service, any citizen can call the Customer Support lines (800 100 100 and 218 100 100) for clarification and confirmation.
The video call service allows you to access the services provided by E-REDES service point assistants remotely, avoiding the need to physically travel, particularly at a time when social contact should be restricted as much as possible.
The video call service can be used to answer questions, submit applications for a new connection to the electricity network, a power increase and submit documentation, among other things.
The platform supporting the video call is Microsoft Teams, which you can access via one of the following devices - smartphone, tablet or computer - with a camera and microphone.

The illegal use of electricity is illegal and harms everyone, starting with you. The safety of people, property and supply is at stake. All behaviour aimed at obtaining electricity supply without paying for it should be reported.
Examples of fraud/illegal acts can be a direct connection to distribution grids or actions that may distort the normal operation of electricity measurement or power control equipment.
By reporting a fraud/illegal act, the situation will be investigated and corrected, which will contribute to greater equality and fairness on how electricity costs are charged.
Reports can be made anonymously. To do so, you should not enter your Name and Telephone Number in the "Contact Details" indicated in the form.
If you think you are not responsible for any irregular use of electricity, you must send documentation that proves so. For instance, if you moved in and the period of irregular consumption corresponds to the stay of a previous tenant, you must send a copy of your lease agreement confirming the date from which you started living in the property. The documentation must be sent via the "Contact Us / Fraud / I have questions about the regularization of an irregular situation" area.

If you are responsible for any irregular electricity consumption, you must pay any outstanding amounts.
You can report the reading using one of the following methods:
Digital Customer Service (Balcão Digital), available on our website;
E-REDES APP (available for Android and IOS);
Our toll-free number for readings (800 507 507, 24h/day)
Through your electricity supplier.

The best date for this is recommended by your supplier on your electricity bill.
If you have trouble submitting your reading, contact our Customer Support Helpline – 218 100 100 (8 a.m. – 10 p.m., business days, national landline call charges).
The installation of smart meters is part of E-REDES’ mission as the Distribution Network Operator, responsible for delivering an excellent public service focused on the customer and promoting the energy transition.
The new meters have a more advanced technology that allows us to increase the quality of the service we provide you, such as the automatic remote collection of readings. In addition, we enhance environmental sustainability and energy efficiency.
E-REDES has carried out, over the past few years, a smart meter installation plan that was completed at the end of 2024. However, there are still Normal Low Voltage (BTN) Consumption Sites that still do not have smart equipment due to lack of access. If you have not yet been contacted for the installation of a smart meter, we suggest that you contact us using the form.
No. E-REDES, as the Distribution Network Operator, is responsible for installing, replacing, operating and maintaining the smart meter, as well as informing the customer about its use. The equipment is owned by E-REDES.
The data collected by smart meters are processed by E-REDES, with due safeguarding of the fundamental rights of the data subject.
These are used exclusively to ensure compliance with legal obligations and the legitimate interests of E-REDES, only for the period strictly necessary for the pursuit of processing purposes and with certain and determinable retention periods.

For more information on how E-REDES processes and protects personal data, you can consult the General Informative Note on Data Processing, available on the E-REDES website under privacy.
The installation of smart meters is supported by E-REDES, as the Distribution Network Operator, and, as such, does not require the payment of any monetary amount.
Yes. The activation or deactivation of the electricity supply, in which it is not necessary for a technician to travel to the site, can be done remotely.
The service must be carried out within a maximum of 24 hours from the moment the request is received from the energy supplier, if the customer has not indicated a preferred date, or from the previously specified date and time. In an emergency situation, the service must be performed within a maximum of 3 hours after the request is received from the energy supplier.
If it is impossible to perform the service remotely, within the maximum deadlines provided, the customer will be informed by E-REDES or by its supplier within 24 hours, so that it is possible to schedule a visit to its place of consumption.
If the payment was not by entity/reference, as stated on the invoice, that is, payment by check or bank transfer, then proof of payment must be sent to cobrancas@e-redes.pt
These situations must be addressed to the Maintenance Area for correction at the registration level. Contacts are available from the phone icon.
These situations must be addressed to the Maintenance Area to verify the matter in detail. Contacts are available from the phone icon.

Meter unsealing consists of removing the seal that prevents it from being altered and may be necessary for a private electrician to carry out some work.
You can request it through the Digital Customer Service on our website. Alternatively, you can visit an E-REDES store.
The “Contact Us” section, available through the Help menu, is an online form where you can ask us your questions or send us documents.
You can report the issue through the "Contact Us / Customer Support / I have difficulties accessing or using the digital channels" section on our website.
Before placing an order you should take into account:

if the HAN module you intend to use respects the defined requirements;

whether your installation is for Normal Low Voltage consumption;

whether you have a smart meter / EMI integrated in the smart grid.

The request for access to the meter's HAN port can be made directly to E-REDES or through your Supplier, giving you access to the serial communication port on the Digital Customer Service. In both cases, this service requires a download of the meter whose associated cost can be found here. The use of a HAN module allows you to access your consumption in real time, including production, if you have solar panels connected to that meter. This way, you can make more informed decisions that allow you to improve the energy efficiency of your installation.

Each module is the sole responsibility of the Customer.
If you are experiencing recurring power interruptions, voltage fluctuations, or lights that are dimmer than usual, please report the issue through the Contact Us section.
Select the "Faults and Public Lighting – I have been experiencing problems with my electricity supply" option and describe the issue so that we can investigate and assist you.
In partnership with Serviin, E-REDES offers a personalized service via video call, through which a Portuguese Sign Language interpreter can help you communicate with an E-REDES assistant.
To do this, the Customer can make a video call via Skype with “Serviin - LGP Interpreter”, indicating to the interpreters that they want to speak to E-REDES and specifying which of the lines they want to contact, according to the availability of the Serviin service:
Customer Helpline (218 100 100) – between 8 a.m. and 10 p.m. on weekdays;
Breakdown Line (800 506 506) – between 8 a.m. and 11 p.m., every day except weekends.
Registration of Customers with Special Needs. Each client is unique. We work daily with a focus on those around us. We present different solutions to our clients.
To start an Autoconsumption process, the customer must first register on the DGEG portal. Once the registration is guaranteed, E-REDES will proceed to the viability analysis of the power to be injected into the grid. If the conditions match those requested, DGEG will grant the registration. If the conditions differ from those requested, acceptance by the customer will be required for the registration to be granted.

Subsequently, E-REDES proceeds with the creation of the Production CPE as well as the analysis of the meter count and substitution or repair of the meter if necessary. Once the registration phase is concluded, the Autoconsumer will have to obtain the certification of the installation from the DGEG. E-REDES will subsequently receive a communication from DGEG, and the Self-consumer's installation will be in operating condition, and the reading of data inherent to the activity of the meter(s) will begin.
If the meter is not suitable for Self-Consumption, E-REDES will replace it at no cost to the Customer. The appropriateness of the meter only occurs after the Customer registers the self-consumption in the DGEG Portal.

If the installed power of the production unit for self-consumption (UPAC) is greater than 4kW, a totalizer meter must be installed to measure the injection of the UPAC at the usage installation. The charges associated with the modem and the GSM telecommunications card are the responsibility of the self-consumer.
In accordance with the legislation in force:

The UPAC with installed power equal to or less than 700 W is exempt from prior control, provided that the injection of surplus into the RESP is not foreseen;

UPACs with an installed capacity of more than 700 W and less than or equal to 30 kW are subject to prior notification;

A UPAC with installed capacity greater than 30 kW and equal to or less than 1 MW is subject to prior registration and operating certificate;

A UPAC with installed capacity greater than 1 MW is subject to the granting of a production and operating license.
Yes, it is possible to change these types of production installation to Self-Consumption. You must go to the DGEG and request the cancellation of your Miniproduction/Microproduction/UPP production installation (DL153/2014), and then make a self-consumption registration on the DGEG Portal. Naturally, it will be necessary to reconvert your existing installation into an Autoconsumption one.
The fourth hour balance is the difference between the consumption data in kW and the data injected into the grid in kW, in each 15 minute period. This means that everything that is produced in that 15 minute interval must be consumed in that same interval. What is not consumed is injected into the grid and another 15 minute cycle is started.
Self-consumers may register and access the Digital Counter, in the Consumption section, to consult the four curves of the load diagram (quarter-hourly), such as the consumption and injection value recorded by the meter.

The data sent each month to the Supplier are presented in the Readings section of the Digital Counter, in which a distinction is made between the meter reading and the final balance that is considered by the Supplier.  
If you have a Microgeneration, Minigeneration, Small Production Unit (UPP) or a Self-Consumption Production Unit (UPAC) with an installed capacity greater than 4 kW, and you have replaced the GSM card in the totalising meter, you can request a communications test through the Contact Us area, selecting “Self-Consumption and Electric Mobility” and “Other”.
You can request this information through the Contact Us area by selecting “Self-Consumption and Electric Mobility” and “I want to know the status of my self-consumption request”.
The production installation must be equipped with protections, at interconnection level, that ensure fast, effective and automatic separation from the electricity distribution networks, as well as providing the function of homopolar maximum voltage protection. Therefore, for Self-Consumption installations with a connection power exceeding 250 kW, the installation of the interconnection/homopolar protection for grid connection purposes is not exempt.
The European Network for Cyber Security (ENCS) and the European Association of Distribution System Operators (E.DSO) have defined a set of requirements to guarantee the safety of electric vehicle charging infrastructures. The aim is to protect the electricity grid from potential hackers who could cause a blackout through poorly protected electric vehicle chargers.
All CPEs with an active contract registered under the Municipality’s Tax Identification Number (NIF) are available.
Detailed information is available for each CPE, including:
Technical data (including coordinates and NIP);
Meter readings;
Consumption data;
Load diagrams.
This means that the CPE does not have a smart metering device installed or that the device is not communicating.
Self-consumption is consumption ensured by electricity produced by Self-Consumption Production Units (UPAC) and carried out by one or more self-consumers of renewable energy.

Collective Self-Consumption consists of a group of self-consumers organised in condominiums of buildings in horizontal property regime or not, or a group of self-consumers located in the same building or area of apartments/houses, industrial, commercial or agricultural units, and other infrastructures located in a delimited area, in a close neighbourhood relationship, which have ACUs and share the energy produced among them.
The collective self-consumption model is based on the association of nearby consumers and production units to share energy. To be designated by its members, the Self-Consumption Management Entity (EGAC) represents collective self-consumption to operators and administrative entities.

The regulation makes the EGAC responsible for the relationship with the Distribution Network Operator to manage energy sharing and make production data available, as well as for the relationship with the aggregator to sell the surplus of collective self-consumption.

Consult the regulation on collective self-consumption here.
Decree-Law no. 15/2022, of January 14, which establishes the organization and operation of the National Electricity System, incorporated the provisions regarding renewable self-consumption (and revoked Decree-Law no. 162/2019, of October 25).

Decree-Law No. 15/2022 provides for the Collective Self-Consumption Regulation, covering matters such as the commercial relationship between the entities involved, the measurement, reading and availability of data, the modes of energy sharing between self-consumers or the application of regulated tariffs and prices.

Consult the regulation on collective self-consumption here.
Renewable Energy Community - a legal entity incorporated pursuant to this Decree Law, whether for profit or not, based on an open and voluntary adhesion of its members, partners or shareholders, which may be natural or legal persons, of public or private nature, including, namely, small and medium-sized enterprises or local authorities, which is autonomous from its members or partners, but effectively controlled by them, provided that and cumulatively:

(a) The members or participants are located in the vicinity of the renewable energy projects or carry out activities related to the renewable energy projects of the respective energy community;

(b) the said projects are owned and operated by the said legal person;

(c) the main objective of the legal person is to provide environmental, economic and social benefits to the members or localities where the community operates, rather than financial gain.
The distinction between Collective Self-consumption (Autoconsumo Coletivo/EGAC) and Renewable Energy Communities (RECs) is related to the definition of its Managing Entity, specifically:

Collective Self-consumption - the Collective Self-consumption Managing Entity (EGAC), is the entity, natural or collective, designated to manage the Collective;

CER - A collective person, profit or non-profit, designated to manage the CER.
The DSO is responsible for ensuring the commercial relationships set out in the Electricity System Regulatory Authority Regulations, as well as for collecting, processing and providing data associated with self-consumption.

The DSO is also responsible for calculating the energy to be shared by the Consumption Facility or Associated Self-Consumption Facility in self-consumption, making the invoices that are applicable in the scope of the legislation and regulations.
To start a Collective Self-consumption process, the Customer must first register on the DGEG portal. As regards the connection process to the Public Service Electricity Grid (How can I connect a Collective Self-consumption to the grid? RESP), the Collective Self-consumption process follows the same procedures as for Individual Self-consumption. Learn more by visiting the Individual Self-consumption page.

The general conditions for contracts for grid use for self-consumption through the RESP were approved through Directive no. 12/2022, of May 19th, published in Diário da República.
In the case of energy sharing within a collective self-consumption, the consumption measured on the meter of the user installation no longer corresponds to the consumption supplied by the Supplier, as the energy shared by self-consumption must be deducted. On the other hand, if the Self-Consumption Production Unit (UPAC) is interconnected with the consumption installation through the public network, network access tariffs will be charged on the value of shared energy (self-consumption through the RESP). This charge is made by the Distribution Network Operator to the Self-Consumption Managing Entity (EGAC).
No. Decree-Law No. 15/2022 does not apply to electricity generation through cogeneration. Cogeneration activities are expressly excluded from the scope of this legislation and continue to be regulated under Decree-Law No. 23/2010 of 25 March, as amended.
An Electric Vehicle Charging Station (PCVE) can be installed in private space (home, work, residential condominium or parking lots) or in public space (public roads).

The connection of a PCVE in public space requires a network connection request that is made through the Digital Counter, by clicking on "Network Connections" and "Companies/Businesses".

In the case of connecting a PCVE in a private space, the following cases may occur:

Space does not have a network connection, so it will be necessary to make a network connection request;

Space within an installation with a grid connection and without power availability for the installation of the PCVE, so it will be necessary to make a request for grid connection to increase power;

Space is inserted within an installation, with connection to the grid and with availability for the PCVE installation, so no change on the grid side will be required.

In addition to the grid connection, any PCVE to be installed in public or private space must comply with the legislation in force, which you can consult in the Technical Guide for Electrical Installations to Power Electric Vehicles available on the DGEG website.

For more information about the electric mobility network, the entities involved and the respective legislation, please contact the Managing Body of the Electric Mobility Network (Mobi.E).
E-REDES suggests prior contact with a responsible technician/electrician, registered in the Directorate-General for Energy and Geology (DGEG), to help prepare the documentation required for the request.

Opening a PCVE connection request implies sending the following documentation:

Electrotechnical sheet (model approved by DGEG) signed by a responsible technician registered at DGEG and filled out in full. The form must indicate the total constitution of the building in question and not only the constitution of the fraction(s);
Address and coordinates of the delivery point;
Municipal building permit, declaration of the competent entity (City Hall, Parish Council) or land registry that attests to the legality of the construction;
Photographs of the delivery point and the surrounding network to characterize the installation site.
Property identification number (if it exists).
The network connection request is made through the Digital Counter, by clicking on "Network Connections" and "Companies/Businesses".
The entities involved in the grid connection process vary according to the type of site where the Electric Vehicle Charging Station (EVPC) will be installed - private sites with private access or public/private sites with public access.

Mobi.E - Electrical Mobility Network Managing Entity, which manages the operations of the electrical mobility network, including the management of energy and financial flows.

Comercializador do Setor Elétrico (CSE) - the entity with which the electric energy supply contract is signed.

For more information on the entities involved in Electric Mobility in Portugal, please consult the website of Mobi.E
In the case of a PCVE connection, the following cases may occur:

Space does not have a grid connection, so a meter will be installed when the connection is made;
Space is already connected to the grid, and an intelligent meter integrated into the intelligent grid is required. If these conditions are not met, E-REDES will make the necessary changes.
If you do not wish to connect to the Mobi.E network, you do not need to change the existing meter in the installation.

For more information see the website of Mobi.E.
Private spaces with private access (Houses, Condominiums, and Companies):

For charging at a conventional outlet, a cable provided by the electric vehicle manufacturer is typically used. The standard power for this type of charging is 2.3 kW. This means that it takes about 6 hours to charge the equivalent of a 100 km range.

In the case of wallboxes - a home charging station - the cable can either be provided by the electric vehicle manufacturer or be integrated into the wallbox. The power of this type of charging station can be between 3.7 kW and 22 kW. In these home charging stations, it takes between 4 hours and 45 minutes to carry out a charging equivalent to a 100 km range.

Sockets:

Schuko (conventional socket)
Mennekes (wallbox)

Public spaces with public access (public roads and other locations) or private access (supermarkets, shopping malls, among others):

There are two types of charging stations: Normal Charging Stations (PCN) and Rapid Charging Stations (PCR).

Normally, Normal Charging Stations provide Mennekes sockets and charging powers between 3.7 kW and 22 kW. In these, the supply is made in alternating current, and it takes between 4 hours and 45 minutes to make a charge equivalent to 100 km of autonomy.

In the case of Rapid Charging Stations, characterized by charging powers above 22 kW, the supply can be made in alternating or direct current. In this case, sockets of the type CHAdeMO or CCS (COMBO) is used, which always have an integrated charging cable. Depending on the type of battery and electric vehicle, a charging equivalent to a 100 km range takes about 20 minutes.

Requests in "Pending Approval" status are pending approval by the Municipality's hierarchical profile, they have not yet been submitted to E-REDES. If you want to proceed, you should “Submit”; if not, you can “Delete”. You can find these options within the request.
Requests in "Budgeted" status are pending acceptance of the budget by the Local Authority. The budget is broken down and the various construction options available appear, from which you will have to choose one: E-REDES, Client and Shared.
If the budget shows costs, the Local Authority enters the budget number and a supporting document and clicks the "I accept the budget" button. This action is possible for the Acceptance and Full profiles.
If the budget does not show costs, the Local Authority accepts it by clicking on the “Authorise execution of the work" button. This action is only possible for the Total profile.
If you choose the Client or Shared construction type, you must formalise the submission of documentation: notice of commencement of work and delivery note using the form https://www.e-redes.pt/pt-pt/contacte-nos (Network Connections and Power Increases → 'I want to add information to my request').
We have defined the value of 41.4 kVA as the requested power above which a prior assessment of the conditions for connection to the low voltage network will be required.
This applies to forms on the platform that are 'Special' (Network Connection, except Works, and Power Increase). In these cases, the request for connection conditions is a precondition that is included in the original request. Subsequently, if the connection conditions are assigned, it is necessary to go to the request and click on the respective button so that it can then be upgraded to the PLR (Acceptance and Total profiles).
The Eventual Connection also has this status, which in this case is terminal. It shows the results of the study in the annex, from which you can sign the respective contract with the supplier.
Yes, the user can request to receive notification by email after submitting the request to E-REDES and also, if applicable, in the "Connection Conditions Assigned", "Budgeted" and "Work Completed" statuses. You can also notify a particular Local Authority user when the request requires internal approval.
That's 180 days. After that, the quote expires, is cancelled and a new request must be created if it is to be reopened. The invoice, which is also attached to the platform, is valid for 30 days.
These situations should be addressed to the Maintenance Area for correction at registration level. Contact details are available on the telephone icon.
The spotlight in question is being processed, i.e. there is already a communication made through any E-REDES channel and therefore it doesn't need to be duplicated. After a visit to the site, the spotlight becomes available again.

E-REDES has a network of repair service providers operating in partnership with UON Consulting, which you may use if E-REDES accepts responsibility for the damages.
If you cannot wait for our response and the equipment is essential for your daily life or for the operation of your business, you should keep the damaged equipment and/or components and consult a qualified technician to assess whether the equipment can be repaired.
If the equipment is repairable, you should keep the repair invoice.
If the equipment is beyond repair and you decide to purchase a replacement, you should obtain a technical report from the qualified technician confirming that the equipment cannot be repaired and identifying the equipment’s make, model, serial number, age, cause of failure and damaged components.
If E-REDES' responsibility is confirmed:
The compensation will be calculated based on the value of equipment with the same technical characteristics as the damaged equipment (for which supporting evidence and the purchase invoice will be requested). For the acquisition of replacement equipment, you may use the platform that supports the purchasing conditions agreed with UON Consulting. For further information, please email plataforma.equipamentos@uon.pt or call 210 328 821. Alternatively, you may purchase the equipment from a retailer of your choice; however, in that case, the compensation amount cannot exceed the value applied by UON Consulting.
There is no defined deadline for the submission of the documentation. However, the process will be closed and subsequently reopened upon receipt of the required documentation.
A renewable energy generation unit is an installation that generates electricity from a renewable energy source.
These generation units produce renewable electricity that can be used for self-consumption, shared within an energy community, stored in batteries, or injected into the electricity grid, depending on the configuration of the installation.
2.1 Bi-directional Meter
A bi-directional meter measures both:
The electricity consumed by the installation; and
Any surplus energy injected into the grid.
This meter is the responsibility of E-REDES. If the existing meter is not suitable for self-consumption, E-REDES will replace or adapt it free of charge.
2.2 Totalising Meter and GSM Card
If your installation has an installed capacity greater than 4 kW, an additional meter is required.
In addition to the electricity meter provided by E-REDES, you must install a totalising meter, which measures the total energy produced by the Self-Consumption Production Unit (UPAC).
The following are the responsibility of the self-consumer:
The installation of the totalising meter;
All associated costs;
The communications modem; and
The GSM card used for remote communications.
The GSM card enables remote data collection, meter readings and monitoring.
GSM Card Requirements
The GSM card must meet the following requirements:
Support Circuit Switch Data (CSD) communications;
Allow incoming calls only (outgoing calls must not be permitted);
Have the SIM PIN disabled;
Be an M2M (Machine-to-Machine) card supporting OTA (Over The Air) and STK (SIM Toolkit) commands;
Include a minimum data allowance of 250 MB.
GSM Card Replacement
If you replace the GSM card installed in the meter and wish to perform a communications test, you may request it through the Contact Us form.
DGEG Registration
The GSM card details must also be registered in the DGEG Portal.
The correct registration of this information is essential to ensure future sale of surplus energy, as this process depends on the successful integration of the meter into E-REDES systems.
Approved Totalising Meters
You can consult the list of approved totalising meters for self-consumption here:
Approved Totalising Meters for Self-Consumption.
A storage battery is an optional component that allows surplus energy to be stored for later use.
By storing excess energy generated by the installation, the battery enables that energy to be used at a later time, helping to increase self-consumption and reduce reliance on electricity drawn from the grid.
Installations with an installed capacity greater than 250 kW must be equipped with interconnection and homopolar protection systems in order to be connected to the electricity network.
These protection systems are designed to:
Ensure the rapid, effective and automatic disconnection of the installation from the electricity distribution network when required;
Provide a maximum homopolar voltage protection function, helping to protect both the installation and the electricity network.
These protections are an essential requirement for the safe integration of higher-capacity self-consumption production units into the network.
For further information, please consult the E-REDES page on Self-consumption production units with a connection capacity above 250 kW.
Every energy community must appoint a Collective Self-Consumption Managing Entity (EGAC). This role may be performed by:
A member of the community;
An electricity supplier;
A condominium manager; or
A third-party company.
The EGAC plays a key role in the implementation and management of Collective Self-Consumption and is responsible for:
Registration and Compliance
Ensuring that the production unit is properly registered and complies with all applicable legal and regulatory requirements.
Operational Management
Monitoring energy production and consumption, while ensuring that energy is distributed efficiently and fairly among all participants.
Maintenance
Ensuring that the production unit receives regular and preventive maintenance in order to maximise efficiency and minimise operating costs.
Payment of Network Access Tariffs
Ensuring the payment to the Distribution System Operator of the Network Access Tariffs applicable to self-consumption through the Public Electricity Service Network (RESP), in accordance with the Collective Self-Consumption Regulation.
EGAC Reserved Area
E-REDES provides a dedicated EGAC portal where the Managing Entity can oversee the entire collective self-consumption process and all installations participating in the community.
Through this area, the EGAC can:
View all installations belonging to the community;
Execute a contract for each new collective self-consumption arrangement that uses the RESP;
Download executed contracts;
Monitor account balances for up to 90 days;
View monthly invoices; and
Perform other management and administrative activities related to the community.
Members of an Energy Community may be consumers, producers, or both.
A consumer has a Consumption Installation and only consumes the energy generated within the community.
A producer owns one or more Self-Consumption Production Units (UPACs), such as solar panels, which generate renewable energy for use within the community.
A member may also be both a producer and a consumer, generating energy and consuming part of that energy simultaneously.
How is the energy shared?
Each member consumes a share of the energy produced according to the energy sharing coefficient defined for the community.
What are the members' responsibilities?
Each member is responsible for ensuring that their own installations comply with the applicable technical and legal requirements.
The Directorate-General for Energy and Geology (DGEG) is the Portuguese public administration body responsible for contributing to the design, promotion and evaluation of policies relating to energy and geological resources, with a focus on sustainable development and security of energy supply.
Within the context of energy communities and self-consumption communities, the DGEG plays a central role:
The community must be registered through the DGEG portal;
The role of each installation within the community must be identified in the system;
The Energy Community Managing Entity (EGAC) can monitor and manage the entire community registration process through the DGEG portal;
DGEG is responsible for assessing the proximity criteria between community members; and
DGEG is responsible for the certification of the self-consumption community.
Through these functions, DGEG ensures that energy communities comply with the applicable legal and regulatory requirements.
The Public Electricity Service Network (RESP) may be used to transport and distribute electricity generated by production units to the consumers of an energy community.
The use of the RESP requires the execution of a Network Use Agreement between the Energy Community Managing Entity (EGAC) and E-REDES.
This agreement establishes the conditions for access to and use of the network, ensuring that electricity is distributed efficiently, safely, and in accordance with the applicable regulatory framework.
E-REDES is the primary operator of the electricity distribution grids in mainland Portugal, managing High, Medium, and Low Voltage networks. Its main objectives are to ensure the supply of electricity and to promote the development of the distribution network that supports the energy transition.
Regarding collective self-consumption, E-REDES is responsible for assessing the network's capacity, replacing and adapting electricity meters, as well as measuring the energy injected into the network and sending this information to the electricity supplier. Contracts for the use of the Public Service Electricity Network (Rede Elétrica de Serviço Público - RESP) are also made with E-REDES.

You should keep the documentation and wait for E-REDES’ decision regarding responsibility for the cause of the damage.
If E-REDES accepts responsibility for the incident, you will be informed accordingly and will subsequently be contacted by UON Consulting, E-REDES’ compensation management partner.
At that stage, UON Consulting will request any documentation required to assess the damages, including technical reports, repair quotations, invoices, photographs, or other supporting evidence relevant to your claim.
When E-REDES accepts responsibility for the incident, in addition to the communication already sent to you, we will open a claim file with our compensation management partner, UON Consulting.
As part of this process, E-REDES will provide UON Consulting with the full list of damages reported in your compensation claim form. UON Consulting will then:
Analyse the reported damages in detail;
Request any additional documentation or evidence required;
Assess the applicable compensation amounts; and
Determine the compensation to be paid, where appropriate.
UON Consulting will subsequently contact you directly regarding the documentation required to continue the assessment and compensation process.
Once the claim is assigned to UON Consulting, they will send you a letter or email requesting all the information and supporting documentation required to assess and determine the damages reported by E-REDES.
Examples of documents that may be requested include:
Technical repair reports;
Repair quotations or invoices;
Photographs of non-electrical damage; and
Other evidence supporting the reported damages.
Track the progress of your claim
From this stage onwards, you can monitor the status of your claim through the UON Consulting Portal using the access details provided in the letter or email sent by UON Consulting.
Follow-up contact
On the same day, or the following business day, UON Consulting may contact you by telephone to:
Confirm receipt of the communication; and
Clarify any questions you may have regarding the requested documentation.
Important
Whenever you contact UON Consulting regarding your claim, you should quote the complaint reference number shown in the “Contact” field at the top of the first page of the communication (letter or email) previously received from E-REDES.
The assessment of damages is carried out by UON Consulting, which determines the damages eligible for compensation and the corresponding compensation amounts based on all the documentation submitted and considered appropriate and valid to support the reported damages.
This assessment may take into account documents such as:
Technical reports;
Repair quotations;
Repair invoices;
Photographs; and
Other supporting evidence relevant to the claim.
Additional inspections may be required
If necessary, UON Consulting may appoint:
A repair technician; and/or
A technical expert (surveyor)
to inspect and assess the damaged electrical equipment in order to verify the reported damages and support the compensation assessment process.
Once the damage assessment process has been completed, UON Consulting will:
Send you a second letter or email communicating the conclusions of the damage assessment and explaining the compensation options available to you.
Issue a discharge receipt (settlement receipt) or compensation receipt, either on the same day or the following day. This document confirms the compensation amount determined for the damages assessed.
What do I need to do to receive the compensation?
You must sign and return the discharge receipt to UON Consulting. Compensation can only be paid after the signed receipt has been received.
Important
UON Consulting may issue discharge receipts progressively as compensation amounts are determined.
Therefore, if part of your claim is still under assessment, you do not need to wait for the entire process to be completed before receiving compensation for the damages that have already been evaluated.
To receive compensation more quickly, you should return each signed receipt as soon as you receive it.
Se o equipamento elétrico não tem reparação ou a reparação for mais cara do que comprar um equipamento novo equivalente (com características semelhantes), poderá escolher entre receber o valor venal do equipamento (respetivo valor atual, considerando a sua antiguidade e uso) ou receber um equipamento de um modelo equivalente. Nesta situação, terá de entregar obrigatoriamente os equipamentos danificados quando receber os novos. Para mais detalhes, leia atentamente o nosso “Modo de Atuação”.

Atenção: Se verificarmos que o equipamento danificado tinha reparação, o valor da indemnização não poderá exceder o custo estimado da reparação.
Relembramos que os equipamentos, mesmo que não tenham reparação, devem ser sempre guardados até ao final do processo, caso a E-REDES entenda que deverá analisá-los.

Smart meters are certified according to the European standard EC Directive 2004/22/EC, regarding energy metering instruments, which attests to the degree of accuracy and reliability. There are several brands and models of smart meters to be installed and may change due to changes in supplier or technological developments that lead to the installation of newer versions. This equipment also vary according to the voltage level, being divided into two large groups, BTN (Low Normal Voltage) and Non-BTN.
To get out of the pendency, in the case of a request for an embargo, the documentation can be sent via the current route or via a new request attaching the new information. To lift the embargo, a request must be created, noting the description and attaching the relevant letter. To extend the expiry date of the initial embargo, a request must also be created, noting the description and attaching the new information.
It is not yet possible to archive documents related to the embargo request sent by E-REDES. The communications went via the current channel to the Municipality.
Smart Metering Plus is a technological solution that facilitates near real-time access to smart meter data. In practical terms, it consists of virtualizing access to the HAN port, which currently can only be done locally and by installing an additional device by the interested party.
This solution includes two main features:
Access to a standardized API for online, near real-time access to smart meter data. This API provides raw data, equivalent to what currently happens with the physical HAN port.
Access to real-time information and new services, made available directly to the end customer through the E-REDES APP and/or Digital Counter.
Energy management at the residential and small business level is becoming increasingly important in the context of energy transition (PV, PCVE, heat pumps, etc.). This energy management requires (almost) real-time knowledge of consumption, production, and connection status to the distribution network.
The Smart Metering Plus solution facilitates access to consumption and production data in (almost) real time, as this data is now available online. This easier access to data will enable the market to develop and promote new services of real value to the customer. These services may be provided by third parties, namely by marketers, energy service providers, and/or aggregators (among others).
As this is a new service currently under development, the pilot project has a number of complementary objectives:
· To test the technological solution and concept in a real environment;
· To obtain customer feedback on the service and interfaces provided (APP, Digital Counter, and API);
· To optimize the solution before any industrialization of the service;
· To prepare for the provision of additional services.
As this is a new service currently under development, the information and services available during the pilot phase will be a subset of the final service.
During this pilot phase, a subset of the information available on the physical HAN interface will be available, in accordance with specification document DEF-C44-509. Specifically, the following quantities will be available: instantaneous imported and exported power (*), imported and exported active energy totalizers, maximum power, and instantaneous voltage (*). [*with phase discrimination in the case of three-phase installations]
At a later stage, after the pilot, the customer will be able to select the subset of information to receive/consult.
Participants in the pilot programme will have access to information through the Digital Counter, the E-REDES app, and a standardised API. In the case of the Digital Counter and the E-REDES app, information will be made available in visual and/or graphic format. In the case of the API, raw data will be made available in standardised format.
The frequency of information updates during the pilot phase will normally be less than 10 seconds.
However, considering that service optimization is one of the objectives of the pilot, there may be adjustments to the frequency of information updates during the course of the pilot.
Participation in the pilot phase does not entail any additional costs for participants.
Up to 700 W: no registration required.
From 700 W to 30 kW: prior notification required, through simplified registration on the DGEG website.
From 30 kW to 1 MW: prior registration and operating certificate required.
Above 1 MW: production licence and operating licence required.
If the connection power exceeds 250 kW, project details must be submitted.
Installation must be carried out by an installation company certified by DGEG, in accordance with current legislation.
If the installed power of the UPAC exceeds 4kW, a totalising meter must be installed to measure the UPAC injection into the installation where it is used. The costs associated with the modem and GSM telecommunications card are the responsibility of the Customer.
You can request a communications test for the meter by going to the Contact us section and selecting ‘Self-consumption and Electric Mobility’ and ‘Others’.
When the Distribution Network Operator (ORD) imposes a limitation on the injection power into the Public Electricity Service Network (RESP), the customer must accept the limitation on the DGEG Portal. It is mandatory to ensure that the Self-Consumption Production Unit (UPAC) is configured not to exceed this limit.
The UPAC must be configured to comply with the maximum authorised injection value, which can be ensured through:
Interconnection protections;
Inverter parameters;
Controls on the generating element itself (e.g. panels, microturbines, etc.).
It is the installer's responsibility to ensure that these settings are correctly implemented. Failure to comply with this limitation may compromise:
The safety of people and property;
The stability of the public electricity grid (RESP).
Therefore, the installer must validate the installation's compliance with the technical ruling issued by the ORD and document this compliance. It is also necessary to submit the limitation certificate to the DGEG.
For production units for self-consumption subject to prior registration and an operating certificate (30 kW < Installed Power ≤ 1000 kW), the installation of interconnection/homopolar protection is required when the connection power exceeds 250 kW.
Production units for self-consumption that are subject to a production and operating license (Installed Power > 1 MW) must always include the installation of interconnection protection, regardless of the assigned connection power.
There are three key entities in market processes:
The Aggregator, a market agent with whom a promoter or self-consumer has entered into a contract for the sale of electricity
The Aggregator Change Logistics Operator (OLMA), responsible for managing aggregator change processes and billing for registrations and changes. REN currently performs the functions of OLMA.
The Distribution Network Operator (ORD), such as E-REDES, responsible for managing direct processes, collecting and making available energy data, and billing for the use of the networks it operates within the scope of collective self-consumption energy sharing.
There are two categories of market processes:
Change processes are processes managed by the Aggregator Change Logistics Operator (OLMA) and can be submitted on the REN Markets portal. All communication during these processes is handled by OLMA as an intermediary between the Aggregator and the Distribution Network Operator. Change processes include:
B021P – Initial contract
B051P – Cancellation of initial contract
B022P – Change of supplier
B053P – Cancellation of change of supplier
C010P – Change of account holder
E011P – Termination of production unit
E051P – Cancellation of termination
Direct processes are processes managed by E-REDES as ORD and can be submitted in the Reserved Area of the E-REDES Supplier, under the ‘Producer Messaging’ tab. All communication during these processes takes place directly between the Aggregator and the Distribution Network Operator. Direct processes are:
A012P – Access to the production RPE
C011P – Change in technical and commercial characteristics
D041P – Change in technical installation (origin ORD)
L051P – Notifications associated with the RPE (origin ORD)
G011P – Provision of energy data (origin ORD)
For units under a guaranteed remuneration scheme with the Last Resort Aggregator, all processes take place directly between the Last Resort Aggregator and E-REDES, through the E-REDES Supplier's Reserved Area.
The Aggregator begins by submitting an initial contract request (B021P) on the REN Markets portal, and the request is forwarded to the ORD, which will carry out a series of technical and administrative checks to validate the data submitted in the request and to ascertain whether the installation is eligible to enter the market. Following this assessment, the request may be validated or rejected. If the request is validated, it follows the expected flow until activation, concluding with an activation message from REN to the Aggregator. If the request is not validated, the process concludes with a non-validation message from REN to the Aggregator, stating the reason for non-validation.
To facilitate and ensure that the request is completed correctly, we recommend that aggregators first submit an A012P request to consult the delivery point registration data.
The new Aggregator must submit an aggregator change process (B022P) on the REN Markets portal, and the request will be forwarded to the ORD, which will carry out a series of technical and administrative checks, similar to those carried out during the initial contracting process. Following this assessment, the request may be validated or rejected. If the request is validated, it follows the expected flow until activation, concluding with an activation message from REN to the Aggregator. If the request is not validated, the process concludes with a non-validation message from REN to the Aggregator, stating the reason for non-validation.
Cancellation processes allow you to interrupt and cancel other processes that are in progress. Once a process has been activated, it cannot be cancelled. Cancellation processes cannot be cancelled either.
The following are cancellation processes:
B051P – Cancellation of initial contract – allows you to cancel a B021P request that is in progress
B053P – Cancellation of initial supplier change – allows you to cancel a B022P request that is in progress
E051P – Cancellation of termination – allows you to cancel an E011P request that is in progress
After changing the ownership of the supply contract (if applicable) and registering the owner of the production unit with DGEG, the aggregator can change the ownership of the sales contract using a C010P process, which should be submitted on the REN Markets portal. If the change of ownership is accompanied by a change of aggregator, the new aggregator may submit only one change process B022P indicating the change of ownership.
By submitting a C011P request, the Aggregator can ask EREDES to update its customer's contact details or address.
An order may be marked as invalid for two main reasons:
inconsistencies between the order details and the details at the installation. In this case, you must resubmit the order with the details correctly filled in. Checking the delivery point details using an A012P request may help you to fill in the contract order correctly
the installation does not yet meet all the necessary conditions for market entry. Depending on the reason, you should contact your customer to resolve the situation.
The Aggregator must interpret the reason for non-validation and act accordingly. If you are unable to resolve the non-validation or if you have difficulties interpreting it, you can submit a request for clarification to E-REDES, in the ‘Requests’ tab in the Reserved Area of the E-REDES Supplier.
Here is a list of some non-validations that may arise in a change request:
Reasons for non-validation and Description/Actions to be taken:
Connection/installed power of the request is not consistent with what is found at the installation level > Validate power values filled in with the DGEG licence and information from A012P.
Conditions for requesting a contract do not exist – The tax identification number (NIF) on the request does not match the NIF on the licence > Confirm that the NIF on the request matches that of the licence holder. Only the licence holder can sell surpluses.
Conditions for requesting a contract are not met – Totaliser not integrated > Customer must install a totaliser meter and purchase a GSM card (submit card details on the DGEG portal).
Equipment does not yet meet the conditions > Customer must ask E-REDES to adapt the meter for self-consumption.
Type of production does not allow this type of request > This may be a UPAC without the possibility of injection into the RESP.
Installation scheduled for removal > DGEG has cancelled the licence/certification. Please check with your customer.
Check with your customer and make sure you have the most recent DGEG record. If the discrepancy is confirmed, you can submit a request for clarification to E-REDES, in the ‘Requests’ tab in the E-REDES Supplier Reserved Area. E-REDES will check with DGEG and correct the data if there is a discrepancy.
The modelling of direct processes with E-REDES is available link.
In cases involving the reconstruction or demolition of buildings or installations, where it is necessary to remove electricity network assets, you must submit a removal request to E-REDES through one of the following channels:
Contact Us (select "Network Diversions and Poles – Other Matters"); or
Customer Service Channels.
Documents required
When submitting the request, you must attach the appropriate form:
Service Connection Removal Request (for the property owner); or
Service Connection Removal Request (for third parties).
The form must be fully completed and signed, and accompanied by the Property Registration Certificate (Caderneta Predial).
We define requirements from the outset, assessing materials, durability and ease of maintenance. This phase ensures informed choices from the design stage onwards.
We choose manufacturers committed to sustainable practices and processes that favour recyclable materials and low impact.
We select suppliers committed to sustainable practices.
During use, we monitor our assets and use advanced analytical models that allow us to determine in advance the behaviour of technical assets over time.
Whenever possible, we reuse assets that are still in good condition and can fulfil their original function at another location in the network, such as smart meters and transformers.
Working with manufacturers or external partners, we recondition equipment, returning it to the network with high standards of quality and safety.
Upon reaching the end of their functional life, assets are sent for responsible disposal, with sorting and separation of materials.
We prioritise waste recovery.
Where applicable, we explore alternatives for reusing obsolete equipment, such as donation.
Before submitting a claim, follow these 3 important steps
1. Carefully identify all electrical and non-electrical damage
A claim can only be submitted once, so you will not be able to add further damages after the claim has been submitted.
For this reason, you should identify all damage resulting from the incident before starting the claim process.
2. Check your equipment and keep any damaged items
Test your equipment to determine which items are no longer functioning correctly.
You should keep all damaged equipment, together with any associated parts or components, until the claim process has been fully concluded.
3. Arrange for damaged equipment to be assessed and repaired
You should seek to repair any damaged equipment as soon as possible, particularly essential household appliances such as:
Water heaters;
Storage water heaters;
Refrigerators and freezers;
Cookers;
Ceramic or induction hobs.
E-REDES recommends contacting a qualified repair technician and requesting a technical report containing:
The make, model, serial number and age of the equipment;
The cause of the fault;
The damaged components;
Whether the equipment can be repaired and, if not, the reason why.
If the equipment can be repaired
Keep the repair invoice and the technical report. If E-REDES accepts responsibility for the damage, these documents will be required to assess the compensation due.
If the equipment is essential and cannot be repaired
If the equipment is essential for daily use, cannot be repaired and you cannot wait for E-REDES’ decision, you may purchase a replacement and keep the purchase invoice.
If compensation is approved, reimbursement will be based on the value of an equivalent item, meaning equipment with characteristics similar to the damaged item, even if you choose to purchase a more advanced or higher-specification replacement.
No, it is not mandatory, but you may attach documents that support your description of the incident
When submitting a compensation claim, attaching supporting documentation is not mandatory.
If E-REDES later accepts responsibility for the reported damages, you will be asked to provide all documentation required to assess and process the compensation claim.
You may attach supporting evidence if you wish
You may choose to include documents that help explain or support the incident, such as:
Photographs of the damage;
Images of the affected equipment;
Other documents relevant to the occurrence.
These documents can assist in clarifying the circumstances of the incident but are not required at the initial submission stage.
You will be compensated based on the repair cost
The maximum amount considered for compensation will be equal to the cost of repairing the damaged equipment, as evidenced by the corresponding repair invoice.
For further details, please consult the Operating Procedure (Modo de Atuação).
Keep the damaged equipment until the claim is concluded
Please remember to retain all damaged equipment until the compensation process has been fully completed, as the equipment may need to be inspected or assessed during the claim evaluation process.
Poderá escolher entre receber o valor venal ou um equipamento equivalente novo.
Se o equipamento elétrico não tem reparação ou a reparação for mais cara do que comprar um equipamento novo, poderá escolher uma destas opções:
- receber o valor venal do equipamento, ou seja, o valor atual tendo em consideração o seu estado de uso e a sua antiguidade.
- receber um equipamento equivalente novo, ou seja, um equipamento com características semelhantes ao antigo. Nesta situação, terá de entregar obrigatoriamente o equipamento danificado ao receber o novo. O equipamento de substituição não pode ser convertido em dinheiro.

Se verificarmos que o equipamento danificado tinha reparação, o valor da indemnização não irá exceder o custo estimado da reparação. Para mais detalhes, leia o Modo de Atuação.
Relembramos que deve guardar todos os equipamento danificados até ao final do processo, caso seja necessário analisá-los.
Yes. Whenever the equipment has any irreparable or non-parameterizable anomaly remotely or in person, the smart meter can be replaced. E-REDES, as the network manager and as the owner of the equipment, has the responsibility to replace them.

It is also possible that communications between smart equipment and E-REDES systems may fail and that these failures are not related to smart meters. In these cases and when the failure is not momentary, E-REDES will have to investigate and solve, whether the issue is of its own systems or equipment or those of third parties.
If communication failures persist and it is not possible to collect information—such as consumption readings—E-REDES may, in specific cases, need to visit the site to gather the necessary data.
Yes. Communications between smart equipment and E-REDES systems may fail. In these cases and when the failure is not temporary, E-REDES will have to investigate and solve, whether the issue is of its own systems or equipment or those of third parties.
If communication failures persist and it is not possible to collect information—such as meter readings—E-REDES may, in specific cases, need to visit the site to gather the necessary data.
Yes. E-REDES always informs customers in advance about the need to replace the smart meter.
You can take the readings on the meter display, where the consumption appears sequentially. For more information, see the user manual.
The best way to know if the meter is working properly is to check that the readings are being collected and arriving at our systems. To make sure that the meter is automatically reporting the reading, and to be able to monitor your consumption and other relevant information, access the Balcão Digital.
However, you can check with the machine some indicators that everything is working correctly — such as the display being on and showing information, the time, codes and reading values.
E-REDES will endeavour to ensure that personal data is processed entirely within the European Economic Area.
Exceptionally, and when strictly necessary for the pursuit of its activities, E-REDES may transfer the personal data collected to third countries or international organisations for which there is an adequacy decision by the European Commission, or subject to appropriate safeguards provided by law (in accordance with Article 46 of the GDPR). When transferring data to third countries or international organizations based on appropriate safeguards, E-REDES will ensure additional measures to guarantee that personal data enjoy a level of protection essentially equivalent to that existing in the European Union.
E-REDES is responsible for the management and maintenance of the infrastructure in various areas, in coordination with the municipalities.

The Kristin Depression caused unprecedented damage on a large scale to different levels of the national electricity grid, simultaneously affecting several regions of the country, particularly the central region.
With more than 1 million customers without power at the peak of the storm and more than 6,000 km of network affected, the phenomenon caused severe destruction and damage to lines, poles, substations and other equipment essential to the supply of energy, which in many cases requires not only repairs but also the reconstruction of sections of the network.
The damage was recorded in several regions of the country, with the highest incidence in the central region, namely in the districts of Leiria, Santarém, Castelo Branco, and Coimbra.

The service is being restored in stages and varies depending on:
- the extent of the damage;
- accessibility to affected locations;
- weather conditions;
- the technical complexity of repairs.
Within the same region, there may be very different situations between localities.
Restoring power supply depends on several operational and safety factors.
In many places, before crews can repair the grid, trees or other debris must be removed, access must be ensured, and the safety of people and infrastructure must be assessed.
When damage is extensive, as is the case here, it may be necessary to rebuild parts of the network, which requires more time and resources. In addition, weather conditions can also affect the work and force its temporary suspension to protect crews and populations.
E-REDES mobilised a large-scale operation to respond to the damaged infrastructure and speed up the restoration of power.
Technical teams, specialised resources and temporary solutions have been mobilised to reduce the impact on the population.
Some of these measures include:
- More than 2,000 operational staff on the ground, reinforced by teams from different areas of Portugal and other countries;
- Use of drones and helicopters to identify damage in areas that are difficult to access;
- Installation of six mobile power stations and more than 500 generators to supply critical and priority areas;
- Laying of cables on the ground to replace sections with many destroyed poles, speeding up replacement.
- Tripled satellite communications capacity and Starlink kits installed in local operations to ensure continuous coordination.
E-REDES currently has 2,400 operational staff mobilised, 2,100 of whom are directly in the field, working on repairing assets, removing debris and vegetation, and transporting generators and materials needed for the technical work required to restore the electricity network as quickly and effectively as possible.
These workers were joined by a reinforcement contingent of 350 operational staff from Madeira, Spain, Italy, France, and Ireland. In addition, there are around 300 people in operation control centres, 100% dedicated to resolving this disaster, and all customer service operators in the contact centre. 
E-REDES has a team of outstanding professionals with whom it works in close collaboration and who are fully committed to restoring power in the areas affected by Storm Kristin.
The companies contracted by E-REDES are currently working closely together to restore normality as quickly and effectively as possible for those most affected by the power outage.
Depression Kristin had an unprecedented effect on the national electricity grid. The degree of predictability we had in light of the warnings issued was completely surpassed by the reality of the devastation the country faced. The storm caused extensive damage to the high, medium and low voltage networks, with 24 substations affected, more than 5,000 poles destroyed and more than 6,000 km of network damaged.
In view of the forecasts we had, E-REDES immediately and preventively activated the Operational Crisis Response Plan at the Disturbed level. On the 29th, a state of emergency was activated, mobilising an initial contingent of 1,200 operational staff, which was reinforced in the following days and now has more than 2,000 operational staff.
The electricity distribution network is designed, installed, and maintained in accordance with established safety rules, depending on the voltage level involved. In carrying out its activities, E-REDES strictly complies with the rules established by the legislator.
Classification as an exceptional event allows its consequences to be excluded when verifying compliance with service quality standards.
Events that cumulatively meet the following characteristics may be considered exceptional:
- Low probability of occurrence of the event or its consequences;
- Cause a significant decrease in the quality of service provided;
- It is not reasonable, in economic terms, for network operators, suppliers or, in the case of autonomous regions, producers to avoid all of its consequences;
- The event and its consequences are not attributable to network operators, suppliers or, in the case of autonomous regions, producers.
Considering that these conditions are met, E-REDES will process the request for classification of recent events as exceptional.
Due to the sudden increase in calls during the Kristin Depression, E-REDES exceptionally reinforced its customer service. All available teams were mobilised and service partners were reinforced. Informative messages were also created on the helpline to speed up call routing and prioritise fault reporting.
The effort significantly reduced average waiting times and increased the number of calls answered.
At the same time, informational notices (SMS) were sent to customers and digital channels (site, WhatsApp and Balcão Digital) were reinforced to facilitate the reporting of incidents and access to updated information.
You can quickly report power outages through E-REDES' digital channels, which have greater capacity during high traffic situations:
- WhatsApp: 913 846 398
- Site: www.e-redes.pt → option “I have no electricity”
- Fault Line: only to be used in emergencies in the most affected areas, due to the high volume of calls. 24-hour contact: 800 506 506

These channels were reinforced during the Kristin Depression to ensure faster responses and avoid prolonged waiting times.
Due to the extent of the damage caused by Storm Kristin, access to infrastructure is severely hampered by external factors such as blocked access routes, unstable weather conditions and large-scale damage requiring complete reconstruction of sections of the network.

The service is being restored in stages and varies depending on:
- the extent of the damage;
- accessibility to the affected locations;
- weather conditions;
- the technical complexity of the repairs.
Within the same region, there may be very different situations between localities.
The Kristin depression corresponds to an external event unrelated to electricity distribution activities, the effects of which could not be controlled or prevented by E-REDES. For this reason, E-REDES cannot be held liable for any damage or loss incurred.
If you still wish to receive this response in writing, please submit your request via this form.
The information is updated whenever necessary on E-REDES' official channels, including website and linkedin.
If you identify electrical infrastructure in this condition, stay away and report the situation immediately to E-REDES (800 506 506 or balcaodigital.e-redes.pt).
All reports will be duly recorded and followed up as quickly as possible, depending on resource management and the prioritisation of interventions.
No. There is no constraint in this regard.
The underground network has advantages, but also limitations:
Advantages
- Greater resilience to extreme weather events.
- Less exposure to fires and falling trees.
- Less visual impact.
Limitations:
- Significantly higher construction costs
- More complex and time-consuming works.
- Repairs are generally slower.
The network development plans (PDIRD-E 2024 and 2020) provide for the progressive reinforcement and modernisation of the network, including more underground solutions wherever technically appropriate and economically viable.
If there is no meter installed or there has never been an electricity contract, you must request a grid connection
If the premises already have an electricity meter installed, or if there has previously been an electricity supply contract at the location, you only need to sign a new electricity supply contract with the supplier of your choice.
If not, you must request a grid connection from E-REDES.

A grid connection request is the formal process through which a customer asks E-REDES to connect an installation to the electricity distribution network.
This request may be required for:
New installations or new constructions;
Increases in power capacity;
Modifications to an existing connection; and
Reconnection of existing installations.
The process generally involves a number of stages, including the submission of the request, technical assessment, payment of the applicable charges, issuance of a quotation (where applicable), execution of any required works, and the final connection of the installation to the electricity network.
There are different types of grid connections, depending on whether you are connecting a new installation, modifying an existing connection, or requiring a temporary or permanent electricity supply.
Connections for new installations
Grid connection for a single-family house
Grid connection for a business or commercial premises
Grid connection for a shared or collective installation (for example, apartment buildings)
Modifications to an existing connection
Power capacity increase: Required when the power you wish to contract exceeds the Maximum Admissible Power (PMA) of your installation. If the desired power is below the PMA, you should contact your electricity supplier instead.
Relocation of the delivery point: Typically involves moving the delivery point and meter location, usually from inside the property to an external location accessible from the public road.
Network diversion: Used to relocate existing network assets, such as poles, lines or other network infrastructure. A valid justification for the request must be provided.
Connections based on the duration of electricity supply
Construction connections: Provide a temporary electricity supply for construction works, either with or without a future permanent connection.
Event connections: Provide electricity for a specific event and only for the period required. These are commonly used for circuses, fairs, festivals, street performances and similar events.

Potential costs associated with the construction of exclusive-use or shared-use network elements, such as poles, cables or distribution cabinets, where required.
These charges are defined by the Energy Services Regulatory Authority (ERSE) and are updated annually.
The cost of the electrical project, where required, is not included in the simulator or connection quotation and remains the responsibility of the customer.
A simultaneity factor is a coefficient used in the design and sizing of electrical installations.
It represents the likelihood that all equipment connected to a circuit will operate simultaneously at their maximum power.
The simultaneity factor ranges from 0 to 1 and is established in accordance with the Technical Rules for Low-Voltage Electrical Installations (RTIEBT). It is used to determine the actual power demand expected from an installation, helping to ensure that electrical systems are sized appropriately and efficiently.
Yes, provided that a Third-Party Authorisation Declaration is submitted
A grid connection request may be submitted by another person on your behalf, provided that the request includes a duly completed and signed Third-Party Authorisation Declaration.
You can download the declaration here:

A permanent construction connection supplies electricity to an installation that will become permanent
A permanent construction connection is used to supply electricity to a construction project that will result in a permanent installation, such as:
A single-family house;
Commercial premises; or
Another permanent electricity installation.
A temporary construction connection supplies electricity to a temporary installation
A temporary construction connection is intended to provide electricity to temporary installations, such as:
Construction sites;
Site compounds;
Repair works; or
Equipment testing activities.
Once the works have been completed, the customer is responsible for removing the temporary service connection and any other components associated with the temporary supply.
Before submitting the request, check two requirements
The power required for the construction works cannot exceed the power intended for the final installation.
The type of grid connection (i.e. overhead or underground) and the number of phases of the service connection must be the same for both the construction supply and the final installation.
If you do not meet both requirements
You will need to submit two separate requests:
A temporary construction connection request to supply electricity during the works; and
A grid connection request corresponding to the final installation type (e.g. single-family house, commercial premises, or another type of installation).
If you meet both requirements, contact a qualified technician first

Before submitting a compensation claim, follow these 3 important steps
1. Carefully identify all electrical and non-electrical damages
A compensation claim can only be submitted once, which means that additional damages cannot normally be added after the claim has been submitted.
For this reason, you should identify all damages resulting from the incident before starting the claim process.
2. Check your equipment and keep any damaged items
Test your equipment to determine which items are no longer working.
Any damaged equipment, together with any associated parts or components, should be retained until the claim process has been fully concluded.
3. Arrange for damaged equipment to be repaired
You should seek to repair any damaged equipment as soon as possible, particularly equipment that is essential to your daily activities, such as:
Water heaters;
Storage water heaters;
Refrigerators;
Cookers;
Ceramic or induction hobs.
E-REDES recommends contacting a qualified repair technician and requesting a technical report containing:
The make, model, serial number and age of the equipment;
The cause of the fault;
The components that have been damaged;
Whether the equipment can be repaired and, if not, the reason why.
If the equipment can be repaired
Keep both the repair invoice and the technical report. If E-REDES accepts responsibility for the damages, these documents will be required as part of the compensation assessment.
If the equipment is essential and cannot be repaired
If the equipment is essential for daily use, cannot be repaired, and you are unable to wait for E-REDES’ decision, you may purchase a replacement item and retain the purchase invoice.
If compensation is approved, reimbursement will be based on the value of an equivalent replacement, meaning equipment with similar characteristics to the damaged item, even if you choose to buy a higher-specification model.
You can report damages to E-REDES by submitting a claim through the Compensation Claims Form available on the E-REDES Digital Counter.
When submitting your claim, you should provide all available information relating to the incident and the damages suffered. If more than one item has been damaged, ensure that all affected equipment and losses are included in the submission.
After the claim is submitted, E-REDES will assess whether it is responsible for the incident and will communicate its decision within 15 working days. If responsibility is accepted, you will be informed of the next steps in the compensation process.
If you are still waiting for E-REDES' response, check the status through the Digital Counter
To track the status of your claim, access the Requests area available in the E-REDES Digital Counter and in the E-REDES Digital App, and select "Faults and Interventions" from the side menu.
If your claim has already been forwarded, check the UON Consulting portal
Once your case has been transferred to UON Consulting, you can follow its progress through the UON Consulting Claims Portal.
To do so, you must register on the portal and create a personal account. After registration, you will be able to consult your claim online. Alternatively, you may contact UON Consulting by telephone on +351 210 328 824.
Whenever you contact UON Consulting regarding your claim, please quote the claim reference number shown in the "Contact" field at the top of the first page of the communication received from E-REDES.
If your claim was submitted through an insurance company
If the damages were reported through an insurance company, all communications between UON Consulting and the claimant will be managed through that insurer. In such cases, you should contact your insurance company directly for updates on the claim.
E-REDES will send its response within a maximum of 15 working days
After you submit your compensation claim, E-REDES has up to 15 working days to assess whether it was responsible for the incident that caused the reported damage and to communicate its decision by email or letter.
If E-REDES accepts responsibility, the response will indicate which damages can be compensated and explain the next steps in the process. If any reported damages cannot be accepted, the reasons will also be provided.
If E-REDES concludes that it is not responsible, you will receive a clear explanation of why the reported damages cannot be compensated.
The time required to assess compensation varies depending on several factors
The time needed to determine the compensation amount depends on factors such as:
Whether a technical inspection of the damaged equipment is required;
The repair timeframe, which may vary depending on the availability of spare parts or repair services;
The submission of any additional documentation requested by UON Consulting.
To avoid delays, submit any requested documentation within 15 working days
If UON Consulting requests additional documents to support the assessment of your claim, these should be provided within 15 working days of the request.
If the requested documentation is not submitted within this period, the claim file will be closed and will only be reopened once the required documentation has been received.
Compensation will be based on the documents submitted or the outcome of an inspection
The amount of compensation will be calculated based on the supporting evidence you provide, such as:
Photographs;
Repair quotations;
Repair invoices; and/or
Other relevant documentation.
Where applicable, the compensation amount may also be determined based on the findings of a technical inspection or assessment.
Compensation will be paid either by bank transfer or cheque.
Yes, but your compensation will never exceed the repair cost
If E-REDES accepts responsibility for the damage and the equipment is considered repairable, the compensation amount will be based on the cost of the repair, not on the cost of purchasing a replacement.
You are therefore free to purchase a new item if you wish. However, the amount reimbursed by E-REDES will not exceed the cost that would have been incurred to repair the damaged equipment.
Keep the damaged equipment until the claim is closed
Please remember to retain all damaged equipment until the compensation process has been fully concluded, as it may be necessary for assessment or verification purposes.
Keep all documents and damaged equipment until the end of the process
Damaged equipment, technical reports, repair invoices and purchase invoices may be required as part of the assessment of your compensation claim.
For this reason, you should retain all damaged equipment and supporting documentation until your claim has been fully concluded.
Send the signed compensation receipts to UON Consulting
Once the damage assessment has been completed, you will receive a second communication containing the results of the evaluation, together with a discharge receipt (compensation receipt) for each damaged item included in your claim.
This document confirms your acceptance of the proposed compensation amount. To receive payment, you must sign the receipts and return them to UON Consulting.
Sign and return the receipts as soon as you receive them
Discharge receipts are issued as compensation amounts are determined. Therefore, if part of your claim is still under assessment, you do not need to wait for the entire process to be completed before receiving compensation for the items already evaluated.
To help speed up the payment process, you should return each signed receipt as it is received, ideally within 5 working days.
The first step to becoming an electricity producer is to obtain a Grid Injection Capacity Reservation Title (Título de Reserva de Capacidade de Injeção na RESP).
This title grants the right to use a specific grid injection point in the Public Electricity Service Network (RESP), with the capacity allocated to the applicant.
Once the capacity reservation title has been obtained, the applicant must obtain a prior control title, which depends on the characteristics of the installation:
Prior Registration (Registo Prévio) for small production units with an installed capacity of up to 1 MW;
Production Licence (Licença de Produção) for installations with an installed capacity of more than 1 MW.
For a step-by-step guide to the process, please consult the E-REDES section on Procedures for the Assessment of Grid Capacity Reception or Injection Requests.
Once you have obtained the capacity reservation title and the prior control title, you must submit a grid connection request to the Public Electricity Service Network (RESP).
The following information is required:
Location plan of the generating facility;
Copy of the Prior Registration, Production Licence, or equivalent authorisation;
Technical Data Sheet (Ficha de Caracterização) of the request.
For more information on the connection process, please consult the RESP Connection Process section, which sets out the steps required for your cogeneration installation to become operational.
Cogeneration is a technology that increases the efficiency of energy resource conversion while simultaneously reducing emissions and operating costs.
Cogeneration refers to the simultaneous production, within an integrated process, of thermal energy and electrical energy or, where applicable, mechanical energy.
The main benefits of cogeneration include:
-Lower electricity and thermal energy production costs;
-Avoidance of electricity transmission and distribution costs;
-Higher overall energy efficiency;
-Reduced pollutant emissions.
These advantages make cogeneration an efficient and sustainable solution for energy production.
The first step to becoming a cogenerator is to obtain an allocation of grid injection capacity reservation.
To apply for a capacity reservation, please follow the steps described in the Capacity Reservation Allocation section of the E-REDES website.
For more information, please consult the Capacity Reservation Allocation section on the E-REDES website.
Once you have obtained your Production Licence or submitted the Prior Communication, you should follow the steps outlined by E-REDES in the RESP Connection Process section.
Completing these steps is necessary for your cogeneration installation to become operational.
Your remuneration scheme may fall under either the Special Scheme or the General Scheme, depending on the characteristics of your cogeneration installation.
Special Scheme
Applies to cogeneration facilities:
With an injection capacity of 20 MW or less; and
Where the prior control title was obtained after the allocation of energy injection capacity into the grid.
General Scheme
Applies to cogeneration facilities that do not meet the conditions of the Special Scheme.
For further information about the Special and General remuneration schemes, please consult the E-REDES page on Remuneration Scheme Modalities.
A standalone energy storage facility is an energy storage system that uses batteries and operates independently from any electricity generation facility or consumption installation.
The storage system is connected to the grid and is capable of injecting energy into the network.
It holds its own installation licence, separate from any generating plant or consumer installation.
For more information, please consult the Energy Storage section.
Co-located storage or hybridisation with a storage unit refers to an energy storage system installed at the same location as a consumption installation or a power generation facility.
It is associated with a generating plant and shares the same grid connection point as the main installation.
Its main purposes are:
To store energy produced by the generating plant to which it is connected;
To support the management of energy production, helping to avoid curtailment or energy losses.
For more information, please consult the Energy Storage section.
The process for connecting an energy storage facility to the grid is the same as the process applicable to electricity generation installations.
Because an energy storage facility injects electricity into the grid, its connection process is similar to that of a generating plant.
Step 1: Obtain a Grid Injection Capacity Reservation Title (TRC)
The first step is to obtain a Grid Injection Capacity Reservation Title (Título de Reserva de Capacidade de Injeção na RESP).
This title grants the right to use a specific injection point in the Public Electricity Service Network (RESP), with the capacity allocated to the applicant.
Step 2: Obtain the required prior authorisation
After obtaining the capacity reservation title, the applicant must obtain the relevant prior authorisation title, depending on the characteristics of the installation:
Prior Registration (Registo Prévio) for installations with an installed capacity of up to 1 MW;
Production Licence (Licença de Produção) for installations with an installed capacity above 1 MW.
Step 3: Submit the grid connection request
Once the capacity reservation title and the prior authorisation title have been obtained, the applicant must submit the grid connection request to the RESP.
The following documentation is required:
Location plan of the installation;
Copy of the Prior Registration, Production Licence, or equivalent authorisation;
Technical Data Sheet (Ficha de Caracterização) of the request.
For additional information on the connection process, please consult the section dedicated to electricity generation, as the process follows the same steps.
You may also consult the section dedicated to energy storage for further details.
Keeping vegetation under control near homes and infrastructure helps prevent the spread of fire.
This includes:
-Clearing brush and dry vegetation;
-Ensuring safety distances around buildings;
-Avoiding the accumulation of flammable materials.
These precautions can make all the difference in the event of a fire.
The use of fire must comply with specific rules and, in many cases, requires authorization.
Before conducting a burn, it is important to:
-Check the fire risk level;
-Adhere to the authorized time periods;
-Monitor the operation until it is complete.
Without these precautions, the risk of ignition increases.
Some equipment emits sparks or heat that can start fires.
To reduce this risk:
-Avoid using machinery on days when the risk is highest;
-Make sure the equipment is in good working order;
-Be mindful of wind and temperature.
When the risk is high, even the slightest oversight can be critical.
Everyday activities can cause fires.
It is important to:
-Use grills only in designated areas;
-Never leave embers unattended;
-Do not throw cigarette butts on the ground.
Most fires start as a result of preventable behavior.

(i) Applicants seeking qualification under Qualification Programme 01/SQF/2021 may, for the purpose of meeting the minimum requirements regarding the number of qualified electricians for the PTS + LV Works + Metering asset class/group, present the number of technicians indicated in Annex 1 holding qualification certificates corresponding to a TET-BT-Networks course with a duration of less than 119 hours, provided that the companies demonstrate or declare that these technicians have at least two (2) years of experience in the role and have not interrupted their TET-BT-Networks activities for a period exceeding six (6) months.
(ii) With regard to the specific chainsaw operator training requirement, technicians holding training of less than sixteen (16) hours will be accepted, provided that the applicant companies demonstrate or declare that these technicians have at least one (1) year of experience in the role.
No. It is not necessary to repeat this information in the other tabs. It is sufficient to identify the TET Manager in the “Specific Information - Networks” tab.
It refers to the date of the TET HV, TET MV and TET LVW training, as applicable.
This information may be entered in the “Chainsaw Operator Training” column, by renaming the column to “Chainsaw Operator Training / MV Cabinet Works”.
The Contracting Authority provides the ESPD with the sections applicable to it already completed, namely:
a) Part I (Information concerning the procurement procedure and the contracting authority).
b) Part III (Grounds for exclusion), including any additional exclusion grounds applicable in Portugal, where relevant.
c) Part IV (Selection criteria), where applicable.
The economic operator must then complete the remaining sections of the ESPD that relate to its own information, namely:
a) Part II (Information concerning the economic operator).
b) Part III (Grounds for exclusion).
c) Part IV (Selection criteria), where applicable.
d) Part V (Reduction of the number of qualified candidates), where applicable.
e) Part VI (Concluding statements).
The main form corresponds to the application page available on the platform and must be completed at the time of submission. There is no separate document available for download or printing.
Once all the required information has been entered into the platform, applicants must submit the form, after which the information will be recorded in the system.
This Qualification System does not provide for the establishment of objective and non-discriminatory criteria or rules aimed at limiting the number of candidates to be invited to tender. Therefore, all qualified entities will be invited to participate in the relevant procurement procedures. As such, Part V of the ESPD is not applicable in this context.
All documents submitted as part of the Qualification Request must be drafted in Portuguese, which shall also be the language used in all procurement procedures carried out under this Qualification System.
Where documents are, by their nature or origin, issued in a foreign language, the applicant must provide a duly certified translation into Portuguese together with the original document.
This declaration, along with any other required declarations, must be submitted through the supplier’s registration area within the Supplier Registration System (SRF), available at Supplier Registration System (SRF).
The information provided in the SRF will then be transferred to the qualification application during its preparation and submission process.
The submission of a Motor Vehicle Third-Party Liability Insurance policy is not mandatory.
The submission of the list of completed works is not mandatory.
For the purposes of qualification under 01/SQF/2021, the BTN Energy Metering – Connections training course, with a duration of 9 days and including 10 hours of TET training, is not considered adequate.
Only technicians holding full TET/BT training (119 hours) will be considered.
As stated in point (e) of Section 2.1 of Annex I of the Qualification Programme, applicants must ensure that all personnel whose roles require specific certification (including TET, HV Cabinet Works, MV Cabinet Works, Metering Teams, Optical Fibre Splicers, Chainsaw Operators, Working at Height, and others) are able to provide the relevant certificates issued by accredited training providers.
Accordingly, applicants must provide evidence that Optical Fibre Splicers have completed specific Optical Fibre Splicing training delivered by a recognised training provider.
An applicant may only obtain qualification in one Qualification Category and must expressly select that category when submitting the qualification request. Failure to do so will result in the exclusion of the application.
The assessment of each qualification request is carried out independently for each Qualification Category. Therefore, the outcome of the assessment applies solely to the category for which the applicant submitted its application.
Accordingly, if an application for the Networks 1 Qualification Category is deemed “Not Qualified”, the applicant may submit a new application for the Networks 2 Qualification Category, should it wish to do so. Under no circumstances will E-REDES consider an application submitted for Networks 1 as eligible for assessment under Networks 2.
Notwithstanding the above, applicants that obtain qualification under the Networks 1 Qualification Category will automatically be considered qualified under the Networks 2 Qualification Category.
The qualification system documents can be accessed through the following path:
E-REDES website; Customers and Partners; Suppliers; Qualification Systems; Documentation / Qualification Systems; Consult
You may also access the platform directly via the following link: https://edpartners.miisy.eu/sqf/do/public/links/eredes
Once on the platform, search for 01/SQF/2021 to view the relevant qualification system documentation.
If you are already registered in the system with an “Elementary” or “Basic” registration level, you must send an email to qualificacao.fornecedores@e-redes.pt requesting an upgrade to the “Advanced” registration level in order to be able to submit a qualification application.
Yes. Applicants must be registered in the Supplier Registration System (SRF), available at Supplier Registration System.
Registration in the SRF is free of charge for all entities wishing to register.
Yes. There is also Qualification System 05/SQF/2014, which applies to individual Work Classes (CO), allowing applicants to select the specific Work Class for which they wish to obtain qualification.
In addition, Qualification System 13/SQF/2013 applies to work carried out in Substations, covering both electrical installation and civil construction activities.
For qualification under Qualification Programme No. 01/SQF/2021, within the Networks 2 Qualification Category, applicants must comply with the requirements set out in Annex I of the Qualification Programme, specifically those applicable to the Networks 2 Qualification Category and, in particular, to the HV/MV Asset Class / Work Group.
The minimum human resource requirements are: 20 HV/MV electricians; and Optical Fibre Splicer; as defined in the above-mentioned Annex.
In addition, applicants must also comply with the requirements established for the remaining asset classes/work groups set out in that Annex.
For the purposes of calculating the number of technicians to be considered for qualification, Sections 2.2.1 (Networks 1 Category) and 2.2.2 (Networks 2 Category) of Annex I to the Qualification Programme specify the required quantities by Asset Class / Work Group, as well as the training certificates that must be provided for the indicated personnel. At this stage, no distinction is made by individual Work Class.
Example:
Networks 1 Qualification Category
Asset Class / Work Group: PTS + LV + Metering
2 (two) Engineers
85 (eighty-five) Electricians
1 (one) technician holding an “MV Cabinets” certificate
In addition, all operatives must hold a TET LV certification, meaning that all 85 (eighty-five) electricians must be certified in TET LV.
For the purpose of submitting a qualification application, consortiums or joint ventures are not required to be registered as a separate entity in the Supplier Registration System (SRF).
However, the registration requirement remains mandatory for each individual entity that forms part of the consortium or joint venture.
There is no restriction on the separate participation of economic operators belonging to the same corporate group within this Qualification System, whether participating individually or as part of a consortium.
Accordingly, economic operators belonging to the same corporate group may, at any time, submit a qualification application either individually or as members of a consortium, provided that they meet all the qualification requirements set out in the relevant Qualification Programme.
With regard to the two Qualification Categories, the following should be noted:
Regardless of the Qualification Category selected (Networks 1 or Networks 2), applicants, whether acting individually or as part of a consortium, must obtain qualification across all asset class groups specified in the Qualification Programme.
The types of works and services to be carried out under future contracts are, as a general rule, similar in both Qualification Categories.
Applicants that obtain qualification under the Networks 1 Qualification Category will automatically be considered qualified under the Networks 2 Qualification Category. Conversely, applicants qualified under the Networks 2 Qualification Category will be qualified only for that category.
The main differences between the two categories relate to the specific qualification requirements that applicants must meet, as set out throughout the Qualification Programme, particularly in Section 9. The qualification requirements for Networks 1 are substantially more demanding than those applicable to Networks 2.
For information purposes, Section 1.6 of the Qualification Programme sets out certain rules and conditions applicable to future procurement procedures depending on the Qualification Category. In particular, it highlights the possibility of creating different groups of lots according to the Qualification Categories (Networks 1 and Networks 2). It is anticipated that the annual value of each contract awarded under the Networks 2 Qualification Category will be less than €7,000,000 (seven million euros).

To become a self-consumer, follow the steps below:
Step 1: Identify your self-consumption profile
The first step is to determine the generation capacity you intend to install based on your electricity consumption. You should also decide whether you want to generate electricity solely for your own use or whether you also intend to export surplus electricity to the grid and/or sell it.
Step 2: Contact a certified installer
The certified installer will help assess the characteristics of your installation and guide you throughout the process.
You can find a list of certified installers on the Directorate-General for Energy and Geology (DGEG) website.
Step 3: Register with the Directorate-General for Energy and Geology (DGEG)
If you intend to export or sell surplus electricity to the grid, or if your installed capacity exceeds 700 W, you must register through the DGEG Self-Consumption Portal.
To complete your registration, you will need the following information:
Your Delivery Point Code (CPE), which can be found on your electricity bill;
The taxpayer identification number (TIN) associated with your electricity supply contract;
The details of the certified installer responsible for your application;
The technical specifications of your installation, as provided by your certified installer.
Step 4: E-REDES will assess your application
Once you have registered on the DGEG portal, E-REDES will be notified and will assess the technical feasibility of your application. If all requirements are met, your application will be approved.
You will then receive a communication from E-REDES containing a link that allows you to track the progress of your application.
Step 5: Wait for your meter to be checked
E-REDES will verify that your electricity meter is suitable for self-consumption. If necessary, it will be reconfigured or replaced at no cost to you.
Step 6: Certify your installation
If your installed capacity exceeds 30 kW, your self-consumption generation installation must be certified by DGEG. Certification requires a prior inspection, which may be carried out by DGEG or by another accredited inspection body.
A list of accredited inspection bodies is available on the DGEG website.
Step 7: Start consuming the electricity you generate and sell any surplus
Once your meter is ready and your installation has been certified (where applicable), you can begin generating and consuming your own electricity.
Any surplus electricity that you do not consume may be exported to the grid or sold to an electricity supplier. For more information, see the FAQ: "How can I export electricity to the grid or sell it to an electricity supplier?"
Step 8: Access your information through the Digital Service Portal
You can view information about your self-consumption installation, including your electricity consumption and the energy exported to the grid, through the E-REDES Digital Service Portal.
Step 9: If your installed capacity exceeds 4 kW, you will need an additional meter
In addition to the electricity meter installed by E-REDES, you must also install a totalising meter, which measures the total electricity generated by your installation. The installation of this meter is your responsibility.
The applicable requirements depend on the installed capacity of the self-consumption generation unit (UPAC):
UPACs with an installed capacity of up to 700 W, with no export of surplus electricity to the grid, do not require registration.
UPACs with an installed capacity between 700 W and 30 kW require a prior notification.
UPACs with an installed capacity between 30 kW and 1 MW require an operating certificate.
UPACs with an installed capacity exceeding 1 MW require both a generation licence and an operating licence.
To become a self-consumer, your installation must include the following equipment:
Renewable energy generation unit (UPAC)
Metering equipment:
Bidirectional meter – measures both the electricity consumed by your installation and the surplus electricity exported to the grid. This meter is the responsibility of E-REDES. If your current meter is not suitable for self-consumption, E-REDES will replace or reconfigure it at no cost to you.
Totalising meter and GSM SIM card – If your installed capacity exceeds 4 kW, you must install an additional meter (a totalising meter), which is the responsibility of the self-consumer and measures the total electricity generated by the UPAC. You will also need a GSM SIM card and a telecommunications modem to enable remote data collection, meter reading and monitoring.
Battery energy storage system (optional) – stores surplus electricity for use at a later time.
Interface protection relay / homopolar protection (required for installations with an installed capacity above 250 kW) – ensures the fast, effective and automatic disconnection of the installation from the electricity distribution network when required.
The totalising meter measures the total electricity generated by the generation unit.
You must install a totalising meter if the installed capacity of your generation unit exceeds 4 kW.
You are responsible for the installation and maintenance
The installation and maintenance of the totalising meter, the telecommunications modem, and the GSM SIM card (the SIM card associated with the meter that enables remote data collection) are the responsibility of the self-consumer, including all associated costs.
The GSM SIM card must meet the following requirements:
Support Circuit Switched Data (CSD) communications;
Be configured to receive incoming calls only (no outgoing calls);
Have the PIN code disabled;
Be an M2M (Machine-to-Machine) SIM card supporting OTA (Over-the-Air) and STK (SIM Toolkit) technologies;
Include a minimum data allowance of 250 MB.
Please refer to the list of totalising meters approved for self-consumption.
Register your GSM SIM card details on the DGEG portal
You must register the details of your GSM SIM card on the Directorate-General for Energy and Geology (DGEG) portal.
This step is essential if you wish to sell surplus electricity, as this is only possible once the totalising meter has been integrated into the E-REDES metering system.
You can start using the electricity you generate once the self-consumption process has been completed.
At the end of the self-consumption process, you will receive a communication from E-REDES confirming that your application has been completed. This communication will also include your Production Delivery Point Code (Production CPE).
From that moment onwards, you can begin consuming the electricity you generate and, where applicable, export any surplus electricity to the grid..
If you generate more electricity than you consume, the surplus can be exported to the grid or sold to an electricity supplier.
If your solar panels generate more electricity than your installation consumes, the surplus electricity will be exported to the electricity distribution grid.
If you wish to sell your surplus electricity, you must enter into a surplus electricity purchase agreement with an electricity supplier.
Request the cancellation of your current generation installation and register on the DGEG Self-Consumption Portal.
To convert your existing generation installation to self-consumption, you must:
Request the Directorate-General for Energy and Geology (DGEG) to cancel the registration of your existing small-scale generation, microgeneration or minigeneration installation.
Register on the DGEG Self-Consumption Portal.
Adapt your installation to comply with the technical requirements for self-consumption.
Yes, provided that your contracted capacity is equal to or greater than the installed capacity of your generation unit.
If your contracted capacity is lower than the installed capacity of your self-consumption generation unit (UPAC), there is a risk that the electricity generated will exceed the capacity supported by the meter.
In such cases, the electricity supply may be automatically disconnected as a protective measure to ensure the safe operation of the electricity network.
Follow these steps to set up a collective self-consumption scheme.
Step 1: Identify the participants and appoint the Energy Community Manager
Any type of premises can participate in a collective self-consumption scheme or energy community, including detached houses, apartment buildings, condominiums and business premises.
The first step is to appoint a representative, known as the Collective Self-Consumption Management Entity (EGAC), which will be responsible for managing the energy community.
Step 2: Register the energy community on the DGEG Portal
The EGAC must register the collective self-consumption scheme or energy community on the Directorate-General for Energy and Geology (DGEG) portal, identifying the role of each installation within the community (consumer, producer, or both).
The registration may also include generation installations that have not yet been built but are intended to become part of the community.
Step 3: Network capacity assessment
DGEG will assess the proximity of the different members of the community, while E-REDES will evaluate whether the electricity distribution network has sufficient capacity to support the collective self-consumption scheme.
E-REDES will also determine whether use of the Public Electricity Network (RESP) is required, enabling the export of electricity to the grid and the sharing of electricity generated by the community members.
Step 4: Track the progress of the application
Throughout the process, the EGAC can monitor the progress of the application through the DGEG portal, while each member can track the status of their own installation through the E-REDES Digital Service Portal.
Step 5: Meter verification
E-REDES will verify that the electricity meters are suitable for self-consumption. Where necessary, E-REDES will replace or reconfigure the meters accordingly.
The producer is responsible for ensuring that any metering equipment not owned by E-REDES complies with the applicable technical requirements.
Step 6: Obtain certification for the energy community
The EGAC must apply to DGEG for certification of the collective self-consumption scheme or energy community.
Once certified, the community will be officially recognised and energy sharing will begin based on a predefined sharing coefficient, which determines how the electricity generated is allocated among community members.
Step 7: Update the sharing coefficient
If the EGAC wishes to change the predefined sharing coefficient, it must notify E-REDES through the Self-Consumption Manager area available on the E-REDES website.
Step 8: Use the Public Electricity Network (RESP)
If, during the assessment process, E-REDES determines that use of the Public Electricity Network (RESP) is required, the EGAC must enter into a network use agreement with E-REDES through the Self-Consumption Manager area.
Step 9: Access information through the Digital Service Portal
To monitor information about your installation, including your electricity consumption and electricity exported to the grid, you can access the E-REDES Digital Service Portal or use the E-REDES Digital mobile app.
A step-by-step guide is also available.
The Sharing Coefficient defines how the electricity generated is allocated among the members of a collective self-consumption scheme or energy community.
Each participant's Sharing Coefficient is defined when the collective self-consumption scheme or energy community is registered and is initially calculated in proportion to their electricity consumption.
Once the energy community has been certified and has entered into operation, the Collective Self-Consumption Management Entity (EGAC) may update the Sharing Coefficients.
The Sharing Coefficient can be changed
If the EGAC wishes to modify the predefined Sharing Coefficients, it must notify E-REDES through the Self-Consumption Manager area.
Report the meter issue through the Contact Us section.
If your electricity meter is not working properly—for example, if the display is blank or the meter has been damaged or vandalised—please report the issue.
To do so, go to the Contact Us section, select Meters – My meter is not working properly, and choose the option that best matches your situation.
In the message field, describe the problem and, if possible, attach a photograph of the meter.
Contact a qualified technician registered with the Directorate-General for Energy and Geology (DGEG).
Before submitting your request, contact a qualified technician (or electrician) registered with DGEG. The technician will help you prepare the required documentation and submit your application.
Gather the required documents
To request the relocation of your delivery point, you will need the following:

E-REDES is responsible for managing, maintaining and replacing electricity meters and may replace your meter without requesting your prior authorisation.
If your meter is not accessible from the public highway, you must ensure that our technical team has access to the installation.
Yes. It is normal for a newly installed meter not to start at zero.
A newly installed electricity meter may already display a reading greater than zero. This is normal.
During the installation, the technician records the reading displayed on the meter, which is used as the initial meter reading for billing purposes.
It is the maximum electrical load that can be used simultaneously.
The Maximum Admissible Capacity (PMA) is the maximum amount of electrical power that can be used simultaneously in an installation without causing the main circuit breaker to trip.
You can view it in the Digital Service Portal
You can check your PMA under Site Details in the E-REDES Digital Service Portal or in the E-REDES Digital app.
The amount payable is calculated using either recorded or estimated electricity consumption, depending on the data available.
Where reliable electricity consumption records are available—that is, records that accurately reflect the electricity consumed during the period in which the irregularity occurred—we use those records to calculate the amount payable.
Where reliable consumption records are not available, we estimate the electricity consumed during that period in order to calculate the amount payable.
We considered the period between the date on which the irregularity was identified and the date on which it was rectified.
To determine the start date, one of the following may be used:
The day following the last meter inspection at which no irregularity was identified;
The date on which a change in the electricity consumption pattern was identified;
A date within the previous three years, in accordance with the applicable regulations.
The end date is the day immediately preceding the rectification of the irregularity affecting the meter.
Explain why you disagree through the Contact Us section.
