The BILL Drivers Act directs the Energy Information Administration (EIA) to analyze and report on what is driving electricity cost increases for residential customers and small businesses across all states. The analysis must break down electricity bills into specific cost components including generation costs, transmission and distribution expenses, taxes and fees, and state policy costs like renewable energy requirements, with comparisons made across the preceding seven-year period. The EIA must complete this analysis within 180 days of the bill's enactment and publish the results in a consumer-friendly format on both the EIA and Federal Energy Regulatory Commission websites. The bill uses existing data sources and requires the Federal Energy Regulatory Commission to provide technical assistance, while explicitly stating that nothing in the law changes how utilities set rates or alters their ratemaking authority.
