ORNL develops interactive charts of annual and monthly plant-level hydropower generation over time using historical data from the Energy Information Administration (EIA). Select a state on the map to drill down to plant-level summaries. Please note: EIA data used for calculating historical trends includes records of hydropower and pumped storage generation and excludes any plants not currently online. Charts were excluded for power plants lacking sufficient historical data for calculating statistics (i.e., containing more than 50% of EIA records between 2002–2013).
