Method and sources

Prices are average retail prices from the U.S. Energy Information Administration's monthly survey of electricity sales (EIA-861M): each customer class's revenue divided by its sales, in cents per kilowatt-hour. They are averages across every customer in the class, not a tariff and not a bill. Year-on-year changes compare the same calendar month, so seasonality cancels. The rate-class gaps compare 12-month average prices for the same reason. EIA revises recent months, and revisions are carried into the next edition. Every figure matches Edition 2 of Electricity Prices by State, and this page updates with each new edition.
