Electricity Monthly Update

With Data for September 2020 Release Date: November 24, 2020 Next Release Date: December 24, 2020

End Use: September 2020

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

Average revenue per kilowatthour figures decreased in twenty-one states and the District of Columbia in September compared to last year. The largest decline was found in Missouri, down by almost 6%. Twenty-eight states increased revenue per kilowatthour compared to last year, led by New Mexico (up over 13%). One state, Kentucky, had no change from last September.
