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 11 states in October compared to last year. The largest declines were found in Delaware (down 6.8%), Maryland (down 4%), and Utah (down 3%). Thirty eight states and the District of Columbia increased revenue per kilowatthour compared to last year, led by California (up 13%), Virginia (up 10%), and Florida (up almost 10%).


Total average revenues per kilowatthour were up 3.3% to 10.48 cents in October compared to last year. The Industrial sector rose the most, up 3.3%. This was followed by the Residential and Commercial sectors, up by 3.0% and 2.6%, respectively. The Transportation sector dropped slightly, down 0.5%. Retail sales were down slightly for the month by 0.2%. The Transportation sector rose the highest of the four, growing by 2.2%. The Residential and Commercial sectors each grew slightly over their levels last October by 1.5% and 0.1%, respectively. Retail sales to the Industrial sector declined from last year, dropping 2.7%.

Retail sales



State retail sales volumes were down in 27 states in October compared to last year. Tennessee showed the largest year-over-year decline, down 7%. Indiana and Wyoming had the next largest declines, down 4.9% and 3.7%, respectively. Twenty three states and the District of Columbia had retail sales volume increases in October, led by Massachusetts (up over 12%), West Virginia (up 8%), and South Carolina (up 6.6%).


Heating Degree Days (HDD) were down in 11 states and the District of Columbia compared to last October. This occurred in California and throughout New England. The largest year-over-year decrease was found in New York. It had a decrease of 103 HDDs, an almost 36% drop. Rounding out the top 5 states with lower HDDs were New Hampshire (down almost 30%), Vermont (down 28%), Maine (down 23%), and Connecticut (down 22%). Twelve states, nearly all in the South, had an over 100% increase in HDDs from October 2016: Texas, Florida, Louisiana, Mississippi, Alabama, Arkansas, Oklahoma, Georgia, Kentucky, Tennessee, New Mexico, and South Carolina.
