Public Lighting – An Instrument of Citizenship

Lighting consumes about 15% of all electricity worldwide and plays a major role in our lives – whether it is lighting buildings in the service and housing sector, industrial lighting, decorative lighting, special lighting and signage. or at the level of Public Lighting – also called “PL”.

National Energy Strategy 2020 

In 2014, the European Union defined the 40-27-27 Strategy with the goal of reducing greenhouse gas (GHG) emissions by 40% of 1990 levels, reducing energy consumption by 27%, and achieving 27% of energy consumption from renewable sources by 2030. 

In this sense, Portugal has framed measures and guidelines in the National Strategy for Energy 2020 (ENE 2020) and in the National Action Plan for Energy Efficiency (PNAEE), and a new period is approaching where the new defined goals will have to be considered, with possible energy efficiency measures to be adopted at the level of Public Lighting.

Technology - the future of LED

New public lighting technologies make it possible to provide visual comfort, safety for people and property, and reduced maintenance needs, in an increasingly sustainable way.

The revolution in solid-state lighting (LED) has led to a reduction in consumption, an increase in equipment efficiency and a reduction in the cost of LED luminaires.

These technologies make it possible to control the luminous flux according to the needs of each moment, as well as improving the direction of that flux, minimising waste and light pollution.  

Another relevant aspect is the physiological response to light, an issue that directly influences our well-being and aims to minimise the impact of artificial light on human health. There are efficient LED technology solutions with a colour temperature that ensure not only good colour rendering, but also avoid negative effects on health. 

The new public lighting systems can also provide new services, where each luminaire has a unique identification and is integrated into an intelligent network that manages the lighting (luminous flux variation, fault detection, predictive maintenance, and biodynamic colour temperature control).

Populations and Local Authorities  

The national energy policy includes ambitious goals for increasing energy efficiency in consumption, to which public lighting can make a significant contribution.   

Public lighting is an asset with great visibility and social impact on Local Authorities and Communities, so the measures adopted are another important step in the partnership between E-REDES and municipalities in terms of energy efficiency programmes with a strong impact on the environment.  

Our aim is to provide Energy Efficiency services, focused on reducing consumption in Public Lighting in municipalities, promoting a reduction in electricity consumption and CO2 emissions. 

E-REDES' investment plan envisages that by the end of 2027, in the absence of additional forms of financing or regulatory changes, the public lighting network will be 100% LED.

Protocols with Municipalities 


E-REDES and the National Association of Portuguese Municipalities (ANMP) agreed to an amendment of Annex I to the contract for the concession of electricity distribution in LV, which allowed the introduction of the LED luminaire as a commonly used material in public lighting. This addendum to the current municipal electricity distribution concession contracts has already been signed and is in effect in almost all municipalities of mainland Portugal.  

Under Annex I to that contract, more than 80 LED luminaire models are eligible for installation on PL networks. 

Under the agreement, priority will be given to the creation of new street lighting networks to replace mercury vapour luminaires and obsolete equipment.

An initiative that reinforces the focus on energy efficiency and intelligent network management, with a clear improvement in the quality of service, in an area of activity that is the exclusive responsibility of the municipalities.

LED technology is now an integral part of E-REDES' business, accounting for around 57% of the 3.2 million luminaires in the Public Lighting network. The growth of this technology will continue over the next few years, incorporating new market trends such as real-time control and monitoring, combined with new network supervision technologies.

Have you detected a malfunction?

  1. If you have spotted a street lamp with a bulb that has stopped working, an intermittent light or even an unlit street, you should inform E-REDES so that the malfunction can be rectified as soon as possible. You can do it simply and quickly on our website or in the E-REDES app. 

    By detecting and reporting these types of malfunctions and problems, you are contributing to a more efficient and safe public lighting network and the well-being of all citizens. 

    If you wish to request the installation of new public lighting fixtures, you should address your request to the local authority (Municipality or Parish Council), as it is the responsibility of the Municipality to define the number of lighting fixtures to be installed and responsible for carrying out the necessary diligences with E-REDES.
