The story behind this New York renewable energy facility
New York has 142 hydropower plants in this category, and Kosterville, in Lyonsdale, sits at #137 of 142 by 2024 electricity produced. It’s a conventional hydroelectric plant, meaning it uses river water flowing through turbines to spin generators, and it draws from the Moose River.
It began operating in 1955 and has two generators with a capacity of 1.0 MW, the most power it can produce at one moment. In 2024 it produced 2.3 gigawatt-hours, a unit for large amounts of electricity, which is about 230 homes’ worth. Northbrook Lyons Falls LLC owns it, and the power is carbon-free.
Environmental impact
Produces electricity without burning fuel, which avoids roughly 890 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 340 tons of waste out of a landfill.*
