Gowanus Generating Station is a fuel oil and natural gas facility consisting of 32 simple cycle combustion turbine units situated equally across four generating barges located in Gowanus Bay in the borough of Brooklyn, New York City. The facility is one of the largest floating generating stations in the world. The site also includes approximately 25 acres of piers and submerged land.  The Gowanus Generating Sation is currently being expanded to provide another 100 megwatts of power, the expansion is known as the The South Pier Improvement Project (SPIP).

Nameplate Capacity: 640 MW
Primary Fuel Type: Distillate Fuel Oils and Natural Gas
Secondary Fuel Type: Kerosene and Distillate Fuel Oils
In Operation Since: 1971
