In 2018, wind energy generated within California totaled 14,244 gigawatt-hours (GWh) or 7.3 percent of the in-state total power generation. Wind energy power plants generating in California during at least part of the year had a total capacity of 6,004 megawatts.
Note: Listings that show “CAISO In-State Wind Generation” indicate an estimate has been used in place of WPRS (Wind Performance Reporting System) data. WPRS came into effect for the 2014 calendar year. Starting in 2015, CAISO generation data may be published as a preliminary estimate until validated WPRS data becomes available. The CAISO estimates do not always carry the source county data so the default is “ALL” to refer to counties in California.
