Utility Hydroelectric Generation by Size and County: 2023

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 or had no utility-scale hydroelectric power generation. Data is from 2023 and is current as of May 29, 2024.
