Cost-Share Accountability Act of 2025

The Cost-Share Accountability Act of 2025 requires the Department of Energy to publicly report on its use of authority under the Energy Policy Act of 2005 to reduce or eliminate cost-sharing requirements for energy projects. Specifically, the department must submit an initial report within 120 days of the law's enactment and then quarterly reports detailing these actions to Congress. These reports will be provided to the House and Senate committees overseeing energy and appropriations, and made publicly available online. The bill does not change cost-sharing rules but adds transparency about when waivers occur.
