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 15 states in December compared to last year. The largest declines were found in Louisiana (down 5%), Maryland (down almost 4%), and New Mexico (down almost 3%). Thirty five states and the District of Columbia increased revenue per kilowatthour compared to last year, led by Hawaii (up over 13%), Nevada, and Florida (both up about 9%).

Total average revenues per kilowatthour were up 1.7% to 10.26 cents in December compared to last year. The Residential and Commercial sectors both increased, rising 2.2% and 1.5%, respectively. The Industrial and Transportation sectors decreased, falling 0.6% and 1.8%, respectively. Retail sales were down overall, by 0.9% for the month. At the sector-level, the Residential sector rose by 0.4% and the Transportation sector increased 1.5%. The Commercial and Industrial sectors both saw declines in retail sales compared to the previous December, down 1.3% and 2.4%, respectively.

Retail sales

State retail sales volumes were down in 29 states in December compared to last year. Hawaii showed the largest year-over-year decline, down by almost 8%. Indiana and Washington had the next largest declines, down 7% and 6%, respectively. Twenty one states and the District of Columbia had retail sales volume increases in December, led by Massachusetts (up almost 13%), New Hampshire (up almost 9%), and Rhode Island (up nearly 8%).

Heating Degree Days (HDD) were down in 20 states compared to last December. The largest decreases occurred in the West, with California having the largest percentage decrease of 29%. Alaska and Oregon had the next largest percent decreases, down 21% and 15%, respectively. Twenty nine states and the District of Columbia had growth in HDDs in December. Florida had the largest percentage increase from the previous year (up 134%), albeit the state accumulates a lower number of HDDs as the heating requirements are much lower than the rest of the country due to the state’s year-round warm temperatures. Louisiana and Alabama had the next largest percentage increases, at 34% and 22%, respectively.
