Welcome to the  California Energy Almanac

California Electricity Producers

California is the most populous state in the nation and the world's eighth largest economy. The state depends upon energy to meet the everyday needs of consumers and power economic growth. To ensure that the state's energy is safe, affordable, reliable, and clean, California has established regulatory oversight for the public and private companies that own and operate our energy supply.
The Energy Commission Siting main page provides current policies, data, and project information.

Electric Utility Companies

California is served by about 81 loadserving entities (LSEs). These are broken down as:

  • Investor-Owned Utilities - 6
  • Electricity Service Providers - 22

Power Plants

In 2014, California companies produced about 68 percent of its electricity from power plants located within our state and from plants that are outside of the state but owned by California utilities. The total electricity imported from the Pacific Northwest and Pacific Southwest, not counting California-owned plants, was 94,360 gigawatt-hours.

The installed capacity of the 1,051 in-state power plants (greater than 0.1 megawatts - MW) totals 86,883 MW. These plants produced 198,908 gigawatt-hours of electricity in 2014.
