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 “IP”.

National Energy Strategy 2020

In 2014, the European Union defined the “Strategy 40-27-27” with the aim of reducing by 4030 and 1990 figures, reducing greenhouse gas (GHG) emissions by 40% and reducing consumption by 27%. 27% of the energy consumed is from renewable sources.

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

Who manages Public Lighting?

EDP ​​Distribuição is the concessionaire of the distribution of low voltage electricity in the 278 municipalities of mainland Portugal, on an exclusive basis.

The implementation, conservation and management of the IP networks is the responsibility of the municipalities, but, under the terms of the concession agreements for the low voltage electricity distribution networks (BT), the municipalities delegated this responsibility to the concessionaire - EDP Distribuição.

However, the management of public lighting (definition of lighting levels and times, type and number of lamps and lamps in service) remains the responsibility of municipalities.

What is street lighting?

Public Lighting is considered to be the lighting installed on public roads with the function of providing the minimum levels of illuminance, luminance and uniformity necessary for the movement and safety of persons and goods.

Technology - the future of LED

New street lighting technologies make it possible to provide conditions of visual comfort, safety of people and property, and reduced maintenance needs in an increasingly sustainable manner.

The revolution in solid-state lighting (LED) has enormous potential for dramatically reducing energy consumption, with cost savings and a doubling of performance expected to reach 200 lm / W (lumen / Watt) in luminaires by 2025.

These technologies allow the control of the luminous flux according to the needs of the moment, as well as improve the directionality of the flux, minimizing waste and light pollution.

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

New street lighting systems can also provide new services where each luminaire is uniquely identifiable and integrated into an intelligent network that manages lighting (luminous flux variation, fault detection, predictive maintenance, and biodynamic color temperature control). ).

Populations and Municipalities

National energy policy has ambitious targets for increasing energy efficiency in consumption, to which street lighting can make a significant contribution.

Public lighting is a highly visible and socially impacting asset in the Municipalities and Communities, so the measures adopted constitute another important step in the partnership between EDP Distribuição and the municipalities in terms of energy efficiency programs and with a strong impact in the area. environmental.

Our goal is to provide Energy Efficiency services, focused on reducing public lighting consumption in the municipalities, promoting the reduction of electricity consumption and CO2 emissions.

By the end of 2020, EDP Distribuição has an ongoing campaign to install 143,428 LED luminaries throughout the country, with a total investment of 18 million euros. Thanks to this investment, it will be possible to reduce more than 11 thousand tons of carbon dioxide (CO2) emissions into the atmosphere.

Who should I go to when I have problems with Street Lighting?

If you have detected a street lamp that has a burnt out lamp, a flashing light or even a dim street, you should inform EDP Distribuição so that the anomaly is corrected as soon as possible. You can do it simply and quickly on our website or in the EDP Distribuição app.

By detecting and reporting these types of malfunctions and problems, you are contributing to a more efficient and safe street 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 (City Council or Parish Council), as it is the responsibility of the City Council to define the number of lighting fixtures to be installed. , being responsible for developing the necessary diligences with EDP Distribuição.

Protocols with Municipalities

EDP ​​Distribuição 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 BT, 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 IP networks.

Under the agreement, priority will be given to the creation of new street lighting networks to replace mercury vapor lamps 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.


Although 78% of existing luminaires are still sodium vapor (about 3 million), LED is the emerging and future technology. Despite representing only 15% of the public lighting park, it is expected to grow between 6 and 8% per year.

EDP ​​Distribuição conducted, in 2017, a study in several regions of the country, with two components: psychosocial and luminotechnical, covering different types of populations (urban, rural, coastal and interior), thus ensuring a national representation for a better understanding of impact of this new technology on citizens' daily lives.
