The Solar Shade Expansion Amendment Act of 2025 aims to enhance solar energy generation in the District of Columbia by requiring the Department of Energy and Environment (DOEE) to conduct a feasibility study on the installation of solar canopies at various locations. The study must analyze at least 20 sites, including public buildings, roadways, and private properties, and evaluate factors such as potential energy generation, benefits of shade, installation costs, and any legal barriers. The bill mandates that starting in Fiscal Year 2027, the District's capital improvement plan must include funding for solar canopies at identified locations, and it allows DOEE to issue grants to private entities for solar canopy projects.

Additionally, the legislation requires an updated study by September 30, 2028, to assess the outcomes of previously installed solar canopies and recommend further installations, financial incentives, and necessary regulatory changes. From January 1, 2030, all new capital projects that can accommodate solar canopies must include them in their design. This initiative is part of the District's broader commitment to transition to renewable energy sources and mitigate the impacts of climate change, particularly in light of recent extreme weather events.
