The story behind this New York renewable energy facility

Of New York’s 142 hydropower plants, Eagle in Croghan ranks #42 by the electricity it produced in 2024. It sits on the Beaver River and uses conventional hydroelectric technology, meaning river water spins turbines to make power. Erie Boulevard Hydropower LP owns it, and it has been operating since 1914.

Its four generators can produce up to 6.0 MW, a measure of the most power the plant can deliver at once. In 2024 it generated 29.3 gigawatt-hours, a unit of energy equal to about 2,900 homes’ yearly electricity use. The plant is served by National Grid.

Environmental impact

Produces electricity without burning fuel, which avoids roughly 11,000 metric tons of carbon dioxide a year compared with producing the same electricity from the national mix of power sources — about the same as keeping about 4,400 tons of waste out of a landfill.*

Nearby places worth exploring
