The story behind this New York renewable energy facility

New York has 142 hydropower plants in this category, and Granby, in Fulton, ranks #39 of 142 by the electricity it produced in 2024. It sits on the Oswego River, which supplies the moving water that turns its machinery.

Granby is a conventional hydroelectric plant, meaning it spins turbines with river flow, with no fuel burned. Owned by Erie Boulevard Hydropower LP, it began operating in 1983 and has 2 generators with a capacity of 10.0 MW. A megawatt (MW) is a measure of how much power a plant can deliver at once. It produced 35.6 gigawatt-hours in 2024, a gigawatt-hour being a large unit of electricity, enough to power about 3,600 homes.

Environmental impact

Produces electricity without burning fuel, which avoids roughly 14,000 metric tons of carbon dioxide a year compared with producing the same electricity from the national mix of power sources — about the same as not burning about 1,600,000 gallons of gasoline.*
