How are these residential prices measured?
EIA divides residential electricity sales revenue by electricity sold. This represents the average across households and providers in the reported area, rather than a specific utility rate plan. Monthly observations may be revised.
County, city and political district boundaries do not define utility territories. The U.S. local lookup identifies possible providers by address and ZIP; its utility prices are dated 2024 averages.
