Northport Power Station
fuel oil and natural gas power plant in Northport, New York
The Northport Power Station, known as “The Stacks” by the locals, is the largest power generation facility on Long Island. It is a natural gas and conventional oil electric power generating station located on the North Shore of Long Island in Fort Salonga, New York. The facility was built by the Long Island Lighting Company (LILCO) in stages between 1967 and 1977, and since August 2007 it has been owned and operated by National Grid USA. The plant's electric output is distributed by Long Island Power Authority (LIPA).
In 2010, National Grid filed a lawsuit against the Town of Huntington to challenge the station's property tax levy, which at $80 million made it the most taxed building in the United States. In September 2020, a settlement for a tax reduction on the facility was reached.
Description
Northport Power Station is the largest power generation facility on Long Island. As of 2021, Northport Power Station consists of four steam turbine units with a nameplate capacity of 387.0 MW each, as well as one gas turbine unit with a nameplate capacity of 16.0 MW, for a total of 1564 MW. In 2020, the steam turbine units together generated 2950.6 GWh of energy, which was about 29% of all locally generated power on Long Island that year, while the gas turbine unit was unused. All units are primarily fueled by natural gas, although the steam units have the capability to burn fuel oil as well.
The four enormous smoke stacks are a defining landmark of Northport and can be seen from up to 36 miles away atop East Rock in New Haven, Connecticut, across the Long Island Sound. At 620 ft (190 m), they are the tallest freestanding structures on Long Island.
