Electricity data by division
The United States is divided into nine divisions by the U.S. Census Bureau. The Edison Electric Institute, or EEI, provides weekly electricity production data by division across the US.
The chart below shows the weekly electricity output and week-over-week changes in production levels.
Production in each division
For the week ended January 2, 2015, each of the divisions across the US reported an increase in electricity production on a week-over-week basis.
The South Central and Pacific Northwest divisions saw the highest jump in week-over-week electricity production. Electricity production surged by 14% in each of the two regions. American Electric Power Company (AEP) and IDACORP, Inc. (IDA) have respectively significant operations in the South Central and Pacific Northwest regions.
After the South Central and Pacific Northwest divisions, the Rocky Mountain region showed the strongest weekly growth in electricity production. It increased by 11% for the week ended January 2, 2015. Xcel Energy (XEL) and MDU Resources Group (MDU) have operations in some of the states within the Rocky Mountain region of the United States.
