Energy Transition

SOLIS3, the Solar Platform of Lisbon, is a free web tool developed by Lisbon’s Environment and Energy Agency, Lisboa E-Nova, to inform and educate people about solar energy. It assists citizens to determine the solar energy potential of their building; estimating its revenues; and provides a step-by-step checklist for implementation. In the future, the agency intends to leverage this platform further to establish a one-stop-shop for solar projects.

Commissioning a 2 MW municipal solar power plant in 2020 is one of the most strategic projects for Lisbon - one of Europe’s cities with the most sunlight hours - to take advantage of solar energy. This municipal investment will be used to charge the public e-fleet of buses and waste management vehicles.

Local solar energy production will also greatly benefit from implementing Citizen Energy Communities and Renewable Energy Communities following transposition of the EU Electricity and Renewable Energies Directives into national legislation.

New opportunities are emerging to empower citizens in the energy transition movement. The municipality is presently drafting a strategy for its own buildings to take full advantage of available roof areas.

Along with other new projects, Lisbon’s energy landscape will change in the coming years.

The new 2 MW photovoltaic (PV) power plant at the Carnide Cemetery, currently under procurement, was initially intended to feed the municipal e-Bus fleet. Now its scope is increasing - under new selfconsumption legislation in place since January 2020 - to provide for municipal-level consumption clusters in buildings and other key facilities, such as the lighting system in the city’s tunnels. In 2020 this will be limited by legislation; and increased in 2021 towards establishing a Lisbon-city energy community. Simultaneously, taking advantage of the new legal framework, a new model is being tested to support vulnerable consumers in social housing through a “solar social tariff”. Consumers will be grouped together at building level to produce in-building and off-building PV electricity; and from 2021 the concept will be fully integrated in the municipal energy community.
