In the town of Maizières-lès-Metz in the Moselle region of France, the housing association Batigère Habitat is launching its first Citizen Community for Self-Consumption (CCD'A) project. This initiative involves the installation of 354 photovoltaic panels on a housing complex that includes 126 social housing units. The project, funded with 33,000 euros by the association Sol Solidaire, features a rooftop power plant with a capacity of 161 kWc. This system is expected to generate electricity primarily for common areas within the housing complex and for individual residences, potentially reducing annual energy costs for households by between 75 and 220 euros. A key feature of the project is its solidarity component. Any surplus electricity generated by the solar panels will be directed to a household managed by AMLI, an organization that supports isolated individuals by providing housing, care, and well-being services. This initiative not only aims to reduce energy bills but also encourages a local model of energy sharing and raises awareness about more responsible energy use among residents. The project is considered experimental and is intended to serve as a model for similar initiatives in the future. It also includes plans to "maximize" the use of the solar equipment by utilizing the last surplus electricity to power building entrances in neighboring structures. This approach could allow the citizen self-consumption community to expand and include other tenants living in nearby buildings. By combining renewable energy production with community solidarity, the project in Maizières-lès-Metz represents an innovative approach to sustainable living. It highlights the potential for local energy solutions that benefit both residents and those in need, while also promoting awareness and responsible consumption practices.
