The CEC addresses barriers to accessing renewable energy in urban environments, particularly for residents who do not have access to private rooftop PV systems. It also supports citizen participation in the energy transition while helping reduce energy costs and increasing awareness of energy consumption and electricity billing. Photovoltaic panels are installed on publicly owned rooftops by the municipal utility company. The electricity generated is shared among households and SMEs located within a 2 km radius of each installation. Citizens participate through agreements for a defined share of the installed PV capacity, typically corresponding to 1 kWp per household, through a fixed annual contribution. In return, the electricity generated from this allocation is deducted directly from their electricity bills. The CEC also includes the development of operational guidelines and awareness-raising activities to support the establishment and long-term operation of urban energy communities.
