The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
The series of storms that battered California caused a lot of damage, but they also will provide a boost in clean hydroelectric power this summer and recharge California's depleted groundwater basins.
California in-state electricity generation by source 2001-2020 (ignores imports which made up 32% of demand in 2018, but varies by year) - 2012 is when San Onofre Nuclear Generating Station shutdown; 2017 & 2019 were high rainfall years California electricity production by type showing seasonal variation in generation
Castaic Power Plant, the largest pumped-storage power station in California. Pumped-storage hydroelectricity is important means of large-scale grid energy storage that helps improve the daily capacity factor of California's electricity generation system. This is a list of all operational pumped-storage power stations in California.
California electricity production by type. California produces more renewable energy than any other state in the United States except Texas. [1] In 2018, California ranked first in the nation as a producer of electricity from solar, geothermal, and biomass resources and fourth in the nation in conventional hydroelectric power generation.

The vast majority of the water arrives as winter rain between December and April, with a smaller, less reliable amount furnished by snowmelt and groundwater through June. Scott Dam, which forms Lake Pillsbury, has a total storage capacity of 74,993 acre-feet (92,503,000 m 3). Project regulations require that the gates at Scott Dam be opened ...
The Big Creek Project was the vision of California engineer John S. Eastwood, who first surveyed the upper San Joaquin River system in the late 1880s and mapped potential sites for reservoirs and hydroelectric plants. In 1895, Eastwood became chief engineer at the San Joaquin Electric Company which made an effort to develop a hydroelectric ...
The Upper American River Project (UARP) is a hydroelectric system operated by the Sacramento Municipal Utility District (SMUD) of Sacramento, California in the United States. The system consists of 11 dams and eight powerhouses that tap the upper tributaries of the American River drainage in the Sierra Nevada for power generation.
