In 2020, hydro-produced electricity used by California totaled nearly 21,414 gigawatt-hours (GWh),or 11.22 percent of California's in-state generation portfolio. A total of 274 hydroelectric facilities with an installed capacity of 14,042 megawatts (MW). The amount of hydroelectricity produced varies each year and is largely dependent on snowmelt runoff and rainfall. The annual average hydroelectric generation from 1983 through 2020 is 34,132.5 GWh.

Hydro facilities in California fall into one of two categories. Facilities smaller than 30 MW capacity are generally considered an eligible renewable energy resource and are referred to as small hydro. These small hydro facilities must be certified for the net MWh to count according to renewable energy portfolio standards. There are a few cases where some hydro facilities larger than 30 MW may also be eligible under specific eligibility criteria. All other hydro facilities are referred to as large hydro.

One of those hydro facilities is the Edward Hyatt Power Plant on Oroville Dam, pictured on the right. According to the Calif. Dept. of Water Resources, the "Hyatt Power Plant was constructed in the bedrock below Lake Oroville. A cavern the size of two football fields was dug out to house the facility." The Hyatt Power Plant is a large hydro facility and is part of California's State Water Project, which is the largest state-built water and power development and conveyance system in the United States. Hyatt is the fourth largest energy producer of all the hydroelectric facilities in California.
