The story behind this New York renewable energy facility
New York has 142 hydropower plants in this category, and Dashville, on the Walkill River in Ulster County, ranks #107 of 142 by 2024 electricity produced. It began operating in 1920 and uses conventional hydroelectric technology, meaning river water spins turbines that turn generators, the machines that make electricity.
In 2024 it produced 9.0 gigawatt-hours, a gigawatt-hour being a large unit of electricity, which is about 900 homes’ worth. Its capacity is 4.8 MW, a megawatt being the most power it can deliver at one moment, spread across 2 generators. Water-powered generation is carbon-free and renewable.
Environmental impact
Produces electricity without burning fuel, which avoids roughly 3,500 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 3,600,000 pounds of coal.*
Nearby places worth exploring
Dashville sits in Ulster County, close to New Paltz, home to SUNY New Paltz, and the Shawangunk Mountains, where Mohonk Preserve and Minnewaska State Park draw hikers and climbers. Kingston’s waterfront and the town of Woodstock are also well-known county landmarks.
