Most U.S. Hydropower Capacity Is In The West
More than half of U.S. hydropower capacity for electricity generation is concentrated in Washington, California, and Oregon. Washington has the most hydroelectric generating capacity of any state and is the site of the Grand Coulee Dam, the largest hydropower facility in the United States. New York has the largest hydroelectric capacity of all states east of the Mississippi River, followed by Alabama.
Most hydropower is produced at large facilities built by the federal government. The West has many of the largest hydropower dams. Many smaller facilities also operate around the country.
