In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2] According to the International Hydropower Association, the United States is the 3rd largest producer of hydroelectric power in the world in 2021 after Brazil and China. [3] Total installed capacity for 2020 was 102.8 GW.
The average cost of electricity from a hydro plant larger than 10 megawatts is 3 to 5 U.S. cents per kilowatt-hour. [48] Hydroelectric plants have long economic lives, with some plants still in service after 50–100 years. [49] Operating labor cost is also usually low, as plants are automated and have few personnel on site during normal operation.

Hydro excludes pumped storage (not an energy source, used by all sources, other than hydro). Total includes net imports. 2021 and 2022 data is from Electric Power Annual 2022; The following tables summarize the electrical energy generated by fuel source for the United States. Electric Power Annual [11] for 2022 data.
"Economic dispatch" (low market price) is the most common, [4] often coinciding with the low marginal cost of hydropower, solar and wind power. [ 5 ] Curtailment is a loss of potentially useful energy, and may impact power purchase agreements .
