The story behind this New York renewable energy facility
Out of 567 solar plants in New York’s clean-energy category, NSF Aurelius Site 4 LLC in Auburn, Cayuga County, ranks #229 by electricity produced in 2024. It uses solar photovoltaic technology, meaning panels that turn sunlight directly into electricity with no fuel burned. Its capacity is 4.9 MW, a megawatt being a measure of the most power it can send out at once.
In 2024 it produced 5.2 gigawatt-hours, a unit for large amounts of electricity, which is about 520 homes’ worth of yearly use. NSF Energy One LLC owns the site, and NYSEG delivers its power to customers. It began operating in 2024.
Environmental impact
Produces electricity without burning fuel, which avoids roughly 2,000 metric tons of carbon dioxide a year compared with producing the same electricity from the national mix of power sources — about the same as keeping about 780 tons of waste out of a landfill.*
