Collective self-consumption

Collective Self-Consumption is understood to mean a group of at least two self-consumers organized into condominiums of buildings in horizontal property regime or not, or a group of self-consumers located in the same building or area of apartments or houses, in a close neighbourhood relationship, industrial, commercial or agricultural units, and other infrastructures located in a delimited area, which have ACUs.

See the Self-consumption and CER Manual and find out more about the Collective Self-consumption legislative guide.

In this scope, the management of self-consumption is guaranteed by:

Collective Self-Consumption Managing Entities (EGAC).
Renewable Energy Communities (REC).
Citizens' Energy Communities (CCE).

In the regime of collective self-consumption, the commercial relationship is ensured by these entities, namely the relationship with the grid operator for the purposes of payment of Grid Access tariffs for self-consumption through the public grid and also the relationship with the aggregator of surplus production for sale on the market.

In turn, the grid operator is responsible for providing data, resulting from the calculation of the energy to be shared by the associated Consumption Plant or Self-Consumption Plant in collective self-consumption, making the applicable invoices within the scope of the legislation and regulations in force, in accordance with the Self-Consumption of Electricity Regulations.

Collective Self-Consumption Process

Collective Self-Consumption has three distinct phases in which several interactions take place between DGEG and the grid operator:

With regard to the Registration, Cadastro, as well as the Certification phase, the process of Self-consumption follows the same procedures as for Individual Self-consumption. Visit the Individual Self-Consumption page and learn more about the topic.

Contracting

After certification by the DGEG and attribution of the collective self-consumption registration number, the EGAC establishes a contract for the use of grids with the RDC, in accordance with the RARI and the RRC, when the configuration of the installations participating in collective self-consumption results in the possibility of self-consumption occurring through the RESP.

In this context, EGAC will have to contact the grid operator to sign the Adhesion Contract for the Use of Grids, in the scope of the Regulation on Electricity Self-Consumption, which you can consult here.

The Network Use Agreement provides the general conditions for the Adhesion Contract for the Use of Networks (CUR) which may be consulted on the ERSE website and also the particular conditions, made available by the network operator in a contractual draft, which may be obtained by contacting apoio.autoconsumo@e-redes.pt.

Data

Energy data is made available to the different participants in the collective self-consumption process, as defined in the Self-Consumption of Electricity Regulations, which you can consult here.

IC/IPR/IA holders, suppliers, EGACs and RECs will have access to data availability on a daily, or daily/monthly basis, according to the image below.

Billing

Billing activity, with regard to access to the grid (RESP), may verify one of the following scenarios:

The energy consumed in the consumption facilities of the collectivity - produced by UPAC with use of the RESP - will be billed to the EGAC.
Energy consumed at the community's consumption facilities - produced by UPRACs not using the RESP - is not billed.
Energy consumed in community consumption facilities - not produced by the ACU but with the use of the RESP - will be invoiced to the Supplier.
The EGAC is thus responsible for paying the Grid Operator the Grid Access tariffs to be applied to self-consumption through the RESP, as defined in the Collective Self-Consumption Regulations.
EGACs will be invoiced according to calculations per Consumption Facility, considering the grid voltage level to which the ACUs that supplied the energy consumed are connected, with invoices being issued on a monthly basis and files being sent with the respective details.
