As energy demand in New York increases, our conventional generation plants are more important than ever to provide safe, reliable power to New Yorkers. 

Through National Grid Generation (GENCO) we safely and efficiently operate conventional generation assets that are vital to security of supply in the Northeastern United States and keep the lights on for two million people on Long Island.

We operate three large steam turbine generating plants in the Long Island generation fleet – Barrett, Port Jefferson, and Northport. In total, the fleet capacity is around 3.8GW, which is about 65% of the peak generating capacity on Long Island. We also own and maintain two large-scale battery energy storage systems, one in East Hampton and one in Montauk, as well as a 23MW solar farm in Riverhead.
