The story behind this New York renewable energy facility

Of the 142 hydropower plants in New York’s clean-energy category, Stewarts Bridge in Corinth ranks #10 by electricity produced in 2024. It sits on the Sacandaga River and has run since 1952, using two generators to turn flowing water into power.

In 2024 it produced 132.7 gigawatt-hours (a unit for measuring large amounts of electricity), which is about 13,000 homes’ yearly use. Its capacity, the most it can produce at one moment, is 38.5 MW (megawatts, a measure of instantaneous power). It is a conventional hydroelectric plant, meaning river water spins turbines to make electricity.

Environmental impact

Produces electricity without burning fuel, which avoids roughly 51,000 metric tons of carbon dioxide a year compared with producing the same electricity from the national mix of power sources — about the same as the carbon absorbed by about 53,000 acres of forest in a year.*

Nearby places worth exploring
