Rocky Mountain Institute
GovernmentRocky Mountain Institute (RMI) is an independent nonprofit focused on accelerating the clean energy transition. Through its Utility Transition Hub, RMI publishes financial and operational data on US regulated electric utilities, including rate-of-return metrics, debt and equity structures, and capacity ownership by state. The organization synthesizes regulatory filings from FERC and the EIA to make utility investment trends visible to policymakers, regulators, investors, and advocates. RMI's research highlights the tension between utilities' emissions commitments and their continued investment in fossil fuel infrastructure, and explores policy levers like federal tax incentives and state regulatory reforms to align utility business models with decarbonization goals.
Pinned datasets
RMI Utility Transition Hub - Utility State Map
Most people think of electricity as local, but many utilities operate across multiple states. If you want to know which states a utility actually generates power in, where it buys or controls plants, and how much electricity it's selling in each place, this is the data. It covers 20 years, so you can see which utilities have grown into new states or shrunk their footprint.
US Electric Utility Parent-Company Crosswalk
When you pay your electric bill, the company taking your money might be owned by a larger parent company that owns dozens of other utilities across the country. This dataset is the map that connects those dots. Look up a utility by its name or ID, and find out who really owns it, whether they trade on the stock market, and what other utilities they run. Useful if you're tracking corporate consolidation in the energy sector, looking at investment exposure to utility companies, or trying to understand who controls the grid in your region.
US Utility Debt, Equity & Rate-of-Return Financials
Electric utilities borrow money and raise capital to build power plants and infrastructure. Regulators set rules about how much debt and equity each utility can use, and what return on that equity they're allowed to earn. This dataset shows you the actual numbers for each utility: how much debt and equity they carry, what they're allowed to earn, what they actually earned, and what their customers are paying for. It's the financial backbone of how electricity rates are determined.
