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 29 states in July compared to last year. The largest declines were found in Nevada (down 10.9%), Mississippi (down nearly 10%), and Georgia (down 9.4%). Twenty states increased compared to last year, led by West Virginia (up 7.2%), Maine (up nearly 5.2%) and South Dakota (up 4.7%).

Total average revenues per kilowatthour were down 2.3% to 10.71 cents in July compared to last year. All sectors were down on the month, from a 7.4% drop in the Transportation sector to a 2.4% drop in the Residential sector. Retail sales were up slightly overall (2.0%) to 367,137 gigawatthours (GWh). The Residential, Commercial, and Transportation sectors showed slight gains of 5.9%, 0.6%, and 0.1%, respectively, while the Industrial sector showed a decline of 2.5%..

Retail sales

State retail sales volumes were down in 12 states in July compared to last year. Maine recorded the largest year-over-year decline, down 9.3%. Oregon, Washington, and California had the next largest declines, all down 6.9 - 5.2%. Thirty-eight states and the District of Columbia had retail sales volume increases in July, led by Colorado (up 7.8%), Arizona, and Michigan (both up 6.9%).

Cooling Degree Days (CDD) were higher across most of the country, up in 43 states and the District of Columbia compared to last July. The largest year-over-year increase was found in Michigan, followed by Alaska, New Mexico, Utah, and Wyoming in the Mountain West, and Maine in the Northeast. Eight states had less CDDs than last July, with these states largely found in the Pacific Northwest and upper Mountain West. Oregon had the largest CDD decrease of any state, followed by Washington, Hawaii, Idaho, North Dakota, and Montana.
