Through the cross-border AQUALITRANS II project, 242 photovoltaic panels were installed in 2023 at the Freixo Wastewater Treatment Plant (WWTP), distributed across the administrative building and the building where water pre-treatment is carried out.
The Self-Consumption Production Unit, with a total implementation area of 619 m2, has an installed capacity of 133 kWp and an annual production of 178 MWh, which has enabled a reduction of approximately 4% in the WWTP’s energy consumption.
This project contributes to the decarbonisation target set for 2030 by the Municipality, within the framework of the Pacto do Porto para o Clima.
AQUALITRANS II is a cooperation initiative between Portugal and Spain, led by the Instituto Tecnológico da Galiza (ITG), which aims to improve management and promote the efficient use of energy in the wastewater treatment sector (WWTP). Augas de Galicia, Instituto Galego de Energia (INEGA), the Instituto de Ciência e Inovação em Engenharia Mecânica e Engenharia Industrial (INEGI) and Águas e Energia do Porto are also participating in this project.
