Shoreham Solar Commons is located in Brookhaven, New York, about 60 miles east of Manhattan, on the site of the former Tallgrass Golf Course.
It was placed into service July 1, and the Long Island Power Authority is purchasing the power under a 20-year agreement.
"As we continue to provide affordable, renewable energy to customers across the United States, we are especially pleased our first renewables project in New York helps meet the sustainability goals and energy needs of LIPA's customers and offers economic benefits to the local community," said Rob Caldwell, president, Duke Energy Renewables and Distributed Energy Technology.
The project is expected to generate between $700,000 and $900,000 in annual tax revenue. The energy produced is estimated to displace 29,000 tons of greenhouse gas emissions annually and create nearly 1 million MWh of renewable energy over its lifetime.
