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 13 states in November compared to last year. The largest declines were found in Maine (down almost 18%), Maryland (down 4%), and Missouri (down 2%). Thirty six states and the District of Columbia increased revenue per kilowatthour compared to last year, led by Nevada (up almost 15%), Oklahoma, and Florida (both up 11).


Total average revenues per kilowatthour were up 2.8% to 10.38 cents in November compared to last year. All four sectors rose slightly, with the Transportation sector rising the most at 2.9%. The Residential, Commercial, and Industrial sectors each rose 2.0%, 2.2%, and 2.0%, respectively. Retail sales were up slightly by 0.6% for the month. The Residential sector rose the highest of the four sectors, growing by 4.6%. The Transportation sector followed with a growth of 1.1%. The Industrial and Commercial sectors each dropped from their levels last November, by 2.9% and 0.3%, respectively.

Retail sales



State retail sales volumes were down in 15 states in November compared to last year. Texas showed the largest year-over-year decline, down 4.1%. Tennessee and Arizona had the next largest declines, down 3.4% and 3.3%, respectively. Thirty five states and the District of Columbia had retail sales volume increases in November, led by Massachusetts (up 17.9%) and Maine (up 8.7%).


Heating Degree Days (HDD) were down in 6 states compared to last November. The largest decreases occurred in the Southwest, where Arizona dropped by 122 HDDs, an over 64% decrease. Likewise, New Mexico went down by 124 HDDs, a 23% decline. The third state in the top 3 was Florida. It had 20 less HDDs in November 2017, a 45% decline. Rounding out the top 5 states with lower HDDs were California and Nevada, both down almost 10% and 9%, respectively. Forty three states and the District of Columbia had increases in HDDs in November. The top seven states, which each had an over 30% increase in HDDs, were all located in the upper Mid-West: North Dakota (up 50.5%), Minnesota (up 44.6%), Iowa and Wisconsin (both up 39%), Illinois (up 34%), Montana (up 31%), and Michigan (up 30%).
