Installed In-State Electric Generation Capacity by Fuel Type

* Note: Operational capacity as of December 31 of each year. Does not include plants that retired within the year.



Data based on CEC-1304 QFER Database as of May 8, 2018.

Capacities for all categories excluding wind are as of Hour Ending 24, December 31 of each year. Wind capacities are total for plants operating during the year; wind capacity at end of year capacity may be different.

These tables and corresponding charts are provided to show the total installed electric generation nameplate capacity of all power plants one megawatt (MW) and larger located within California, and the corresponding generation from these resources. The data is collected under the authority of the California Code of Regulations, Title 20, Division 2, Chapter 3, Section 1304(a)(1)-(2).

The information in these charts and tables is based on metering at each power plant site and, therefore, does not account for the 7-8 percent (typical) loss attributed to transmission for delivery to the customer's meter. In addition, the information includes both non-retail sales (for example, water delivery) and retail sales. Thus, the information cannot be used to determine progress toward the Renewable Portfolio Standard. Also, the information does not include power plants with a nameplate capacity of less than one megawatt (1 MW) such as rooftop solar installations, other small distributed generation, backup power generators, or imported energy from surrounding control areas. Data is subject to change based on revisions and quality control checks.
