Lisbon City Council is preparing to modernize 22% of the city's public lighting network with LED technology and a remote management system, expecting to save 70% of energy consumption and save €1.8 million per year.

Lisbon has around 72,000 public lighting points, which consume 53.5 Gwh (gigawatt-hours) of energy per year. The city's lighting infrastructure corresponds to about 75% of the annual electricity bill consumed by the Chamber. To save this cost and the environment, the municipality is preparing to modernize 16,135 luminaires with LED technology and an internet-connected management system. With this first intervention in 22% of the public lighting network, it expects to save €1.8 million per year. In the future, the plan is to modernize the remaining network.
In order to implement this measure of energy efficiency and savings for the municipality's accounts, the Lisbon City Council will enter into a contract with an energy supply company, to be selected by tender, to Energy Efficiency Management Contract (CGEE), similar to what 57 other national municipalities already have or are also doing, such as Palmela, Seixal, Barreiro, Montijo, Moita and Setúbal.
This contract, which will last for 16 years and represents a total investment of approximately €21.2 million, will enable Lisbon City Council to receive a "turnkey solution" for 22% of its public lighting network. In addition to the replacement of these light points with LED lamps, a remote management system for the modernized luminaires will also be installed, with a view to reducing the number of luminaires. smart-cityThis allows for a digital infrastructure control center that communicates with the infrastructure.

According to the municipality, "this investment will result in electricity savings of around 70%" and it is estimated that it will translate, "after amortization of the investment and payment of the service" 456 per year for Lisbon City Council. The investment, to be borne by the energy company selected in the tender to be launched, will be based on a logic of sharing the savings obtained. That is, the energy company will modernize the light points and install the management system and, over the 16 years of the contract, will share with the City Council a remuneration corresponding to 25% of the amount of energy saved.

"Public lighting is an important public service provided by the Municipality of Lisbon to the community, being the component with the greatest expression in terms of its electricity consumption, representing about 75% of the total and being, therefore, a priority area for action to reduce energy consumption and carbon intensity of municipal activities“, points out the municipality in the proposal that was discussed at the Executive meeting. "In Lisbon's public lighting (IP) network, which consists of around 72,000 light points, lighting technologies prevail that no longer guarantee energy or light performance at the level of efficiency currently possible and desirable."'
The numbers
72,000 light points throughout the city of Lisbon, consuming 53.5 Gwh (gigawatt-hours) of electricity per year;
The city's public lighting network accounts for 75% of the annual electricity bill consumed by Lisbon City Council;
Of these, 16,135 light points will be modernized with LED technology and remote management system, corresponding to 22% of the total public lighting network, consuming 16.019 MWh per year (about 30% of total consumption) and an expense of €2.643 million for the Chamber;
This modernization will save around 70% of electrical power, allowing an annual reduction in electricity consumption and cost of approximately 11 MWh and 1.824 million euros.

It was carried out by Lisboa E-Nova, Lisbon's energy and environment agency, an audit of the public lighting network in "a set of pilot areas in the city" with the aim of "characterize the energy consumption in lighting systems, having identified a total of 16,135 conventional luminaires, representing 22% of the Lisbon public lighting park, which can be replaced by LED technology".
This audit estimates that the average consumption of these luminaires is 16.019 MWh per year, which represents an annual expense for the municipality's coffers of EUR 2.643 million. It is expected that, with this intervention alone, 22% of the city's total lighting (which represents almost 30% of the current total consumption) will be replaced. a decrease in the power consumed by 70%, which will represent, over the life of the contract to be concluded, an annual reduction in consumption and cost of electricity of approximately 11 MWh and EUR 1.824 million respectively.

The more than 16,000 luminaires to be replaced and modernized will be throughout the city, in locations and axes identified in the audit. The first step towards the realization of this project was the recent approval by the Executive of a proposal that will allow the launch of the tender through which the supplier of the Energy Efficiency Management Contract will be found. - This approval was achieved with the votes in favor of the PSD/CDS-PP leadership, which governs the city without an absolute majority, and the PS, the abstention of Livre and Cidadãos Por Lisboa, and the votes against of PCP and BE. The proposal will now have to go to the Municipal Assembly, where it is also expected to be approved.
For Carlos Moedas, Mayor of Lisbon, this step is important for the city's carbon neutrality in 2030. "The Municipality of Lisbon is committed to the city's energy transition and to the implementation of policies and concrete actions that will allow it to achieve climate neutrality by 2030. The energy requalification of the public lighting network is a very relevant measure to achieve this goal and to make Lisbon a more sustainable city".it said in a statement.
