To require a report on Puerto Rico's progress toward rebuilding the electric grid and detailing the efforts the Federal Government is undertaking to expedite such rebuilding, and for other purposes.

HR 3878 requires the Secretary of Energy, with federal agency and Puerto Rico government input, to submit a detailed report to Congress within 180 days of enactment. The report must analyze Puerto Rico's electric grid rebuilding progress, including priority projects, funding allocation and disbursement, federal efforts to speed up work, and accountability measures for grid rebuilding. It also mandates an analysis of the Financial Oversight Board's role, recommendations to reduce outages, and a plan to expedite rebuilding within three months of the report's submission. This bill directly affects federal agencies (Energy, FEMA, HUD), Puerto Rico's government, and the Puerto Rico Electric Power Authority by requiring transparency and coordination on grid recovery. The report will be submitted to specific congressional committees focused on energy, natural resources, and infrastructure.
