Electricity Monthly Update
With Data for December 2013 | Release Date: Feb. 21, 2014 | Next Release Date: Mar. 21, 2014
End Use: December 2013
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
In December, the vast majority of US states, 41 out of 50, had average revenue per kWh figures higher than last December. Rhode Island (up 33.5%), Massachusetts (up 21.5%) and Idaho (up 13.8%) had the highest increases. Only nine states had average revenue per kilowatt figures lower than they recorded last December, led by West Virginia and Tennessee with decreases of more than five percent.
Retail Service by Customer Sector
Average Revenues/Sales (¢/kWh) Retail Sales (1000s MWh) End-use sector December 2013 Change from December 2012 December 2013 Change from December 2012 Year to Date Residential 11.72 0.9% 128,357 12.4% 1,391,090 Commercial 9.98 1.7% 108,849 4.5% 1,338,448 Industrial 6.62 1.5% 76,205 -2.8% 954,725 Transportation 10.17 -1.1% 665 7.5% 7,525 Total 9.88 2.5% 314,076 5.6% 3,691,789

Total average revenues per kilowatthour averaged 9.88 cents in December, up slightly from November's 9.83 cent average and an increase of 2.5 percent from last December. The commercial sector had the largest increase from last year, 1.7 percent, followed by the industrial (1.5%) and residential (0.9%) sectors. The transportation sector, a small component of total, was down 1.1% from last December.
Total retail sales volumes increased 5.6 percent from last December to 314,076 GWh. This is largely due to the much colder weather most of the country experienced this December. The residential sector, most sensitive to low temperatures, had a 12.4 percent increase in retail sales volumes from last December while commercial sector volumes rose 4.5 percent. The industrial sector, much more immune to changes in temperature, was down 2.8 percent from last December.
Electric industry retail sales volumes rose in all but four states in December relative to one year ago. Texas, Arkansas, South Dakota and Oregon all had retail sales volume increases higher than 10 percent from last year. Only Kentucky, Alaska, Massachusetts, and Hawaii had lower retail sales volumes this December compared to last December.
Kentucky's sales volumes continue to be significantly lower than previous years' levels due to the closure of United States Enrichment Corporation's Paducah Gaseous Diffusion Plant in Paducah, KY. This facility was a large consumer of electric power and its absence makes a noticeable difference in Kentucky's retail sales volumes.
This December saw the arrival of cold winter weather across much of the country, especially when compared to a mild December 2012. Only Florida, California, and Alaska had lower heating degree day (HDD) totals this December than last year. The colder weather relative to last year was most pronounced in the South and Midwest as Texas, Louisiana, Illinois, Mississippi, Wisconsin, Arkansas, Oklahoma, Missouri, Indiana, and Michigan all had increases of more than 30% HDDs compared to last December.
Relative to long-term normal levels (see the second tab), most states in the Southeast and Mid-Atlantic regions were actually warmer than normal, though cooler than in 2012.
