Cost-Share Accountability Act of 2025

This measure makes the Department of Energy share more information with the public about when it lowers or waives the “cost-share” that nonfederal partners would normally have to pay on federally funded energy projects. The agency must post reports that explain how often and why it used this power. The first report is due within 120 days after the law takes effect, and then at least every quarter after that. These reports must be publicly available, improving transparency around spending on energy research, testing, and early market projects .

Key points

• Who is affected: The Department of Energy and groups that receive DOE funding for research, development, demonstration, or early commercial projects (like companies, labs, and universities).
• What changes: DOE must regularly report, and make public, how it reduced or removed required nonfederal cost-sharing on these projects.
• When: The first public report is due within 120 days of enactment, then at least every quarter after that .
