The order is by residential customers in California. Each figure is for all customers of the utility in California. EIA has no figure for one county. A small utility files a short form with totals only, so it has no residential price.

Revenue for all sectors of the small utilities that file the short form, 2024:

  • Lathrop Irrigation District: 22.03 cents per kWh
  • Port of Stockton: 15.52 cents per kWh

Average price of electricity to ultimate consumers represents the cost per unit of electricity sold and is calculated by dividing electric revenue from ultimate consumers by the corresponding sales of electricity.

The average price of electricity to ultimate consumers reported in this publication by sector represents a weighted average of consumer revenue and sales, and does not equal the per kWh rate charged by the electric power industry participant to the individual consumers.

In plain words: the average price is revenue divided by sales. It is not the rate on a rate schedule. The annual figures on this page are for 2024. Monthly data through .
