Electricity prices in Iowa over time

Each year is the simple mean of its monthly prices. EIA's own annual average weights each month by sales, so it can differ slightly.

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.
