The Solar Shade Expansion Amendment Act of 2025 aims to enhance solar energy generation and provide shade in the District of Columbia by requiring the Department of Energy and Environment (DOEE) to conduct a feasibility study on installing solar canopies at a minimum of 20 locations. These locations will include District-owned properties, roadways, sidewalks, bike lanes, and private properties. The study, due by January 1, 2026, will assess the potential for solar energy generation, the benefits of shade, installation costs, and any legal or administrative barriers. It will also identify specific sites for solar canopy installation during Fiscal Year 2027.

Furthermore, the bill mandates that starting January 1, 2027, the District's capital improvement plan must include funding for solar canopies at identified locations, and DOEE is authorized to issue grants to private entities for solar canopy projects. An updated study is required by September 30, 2028, to evaluate the outcomes of installed canopies and recommend further installations and financial incentives. Beginning January 1, 2030, all new capital projects where feasible must include provisions for solar canopies.
