Electricity Monthly Update

With Data for September 2022 Release Date: November 23, 2022 Next Release Date: December 22, 2022

End Use: September 2022

Retail rates/prices and consumption

In this section, we look at what electricity costs and how much is purchased. Charges for retail electric service are based primarily on rates approved by state regulators. However, a number of states have allowed retail marketers to compete to serve customers and these competitive retail suppliers offer electricity at a market-based price.

EIA does not directly collect retail electricity rates or prices. However, using data collected on retail sales revenues and volumes, we calculate average retail revenues per kWh as a proxy for retail rates and prices. Retail sales volumes are presented as a proxy for end-use electricity consumption.

Average revenue per kWh by state

Forty-seven states and the District of Columbia saw increased revenue per kilowatt-hour (kWh) compared to last September. The largest percent increase was in New Hampshire, up 39.2%, followed by Nevada, up 37.3%, and Hawaii up 36.2%. Average revenue per kWh figures decreased in three states in September compared to last year. The largest decline was found in North Dakota, down 5.9%, followed by Alaska, down 2.8%, and South Dakota, down 0.8%. In the contiguous US, New Hampshire, California, and Connecticut had the highest average revenues at 24.67, 24.34, and 23.34 cents per kWh, respectively.
