The Self-Consumption Production Unit at the Wastewater Treatment Plant (WWTP) of Sobreiras consists of 635 photovoltaic panels that produce clean energy to power the WWTP’s operations.
These panels have a capacity of 387 kilowatt-peak (KWp) and an estimated production of 619 megawatt-hours (MWh) per year, representing savings of around 80.000 euros per year on the energy bill.
The unit covers the administrative building and the roof of the WWTP’s treatment facilities, with a total installation area of 1.715 m².
This project is a clear example of how the city’s electrical infrastructure is being modernised to promote renewable energy production and reduce Porto’s environmental footprint, in line with the Pacto do Porto para o Clima 2030.
