Utility Hydroelectric Generation by Size and County: 2024

Energy generation data and map are from the California Energy Commission for all power plants that have a nameplate capacity of 1MW or more. Hydroelectric plants are designated as a renewable energy source if their nameplate capacity is 30MW or less. Counties without symbols either did not report data, had no utility-scale hydroelectric power generation, or generation rounded to 0. Generation was rounded to nearest whole number. Data is from 2024. Projection: NAD 1983 (2011) California (Teale) Albers (Meters). For more information, contact John Hingtgen at [phone].
