Customer counts are electric meters (accounts), not people. One utility can report several kinds of service in the same state: bundled service, delivery only or energy only.

Frequently asked questions

How do I find my electric utility?
Open your county or city page on this site. It lists every utility that reports serving that county to EIA. Your bill or meter also shows the utility name.
What is the difference between an investor-owned utility, a cooperative and a municipal utility?
Investor-owned utilities are companies owned by shareholders and regulated by a state commission. Cooperatives are owned by their members, often in rural areas. Municipal utilities are run by a city or town. Some states also have public power districts and federal power agencies.
What is a retail power marketer?
In states with retail choice, customers can buy electricity from a retail supplier while the local utility still delivers it. Those suppliers report energy sales to EIA but do not own the wires.
