The story behind this New York renewable energy facility
New York has 567 solar plants in this category, and Glen Mary 1 in Tioga ranks #69 of 567 by 2024 electricity produced. Its solar photovoltaic panels (flat panels that turn sunlight directly into electricity) began operating in 2021. The plant is owned by Generate Capital and connects to the NYSEG system.
Its capacity is 4.9 MW, a megawatt being a measure of the most power it can deliver at one moment. Over a year it produced 8.2 gigawatt-hours, a unit for large amounts of electricity, which is about 820 homes’ worth of use. Like all solar, it makes power without burning fuel.
Environmental impact
Produces electricity without burning fuel, which avoids roughly 3,200 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 3,300,000 pounds of coal.*
