The story behind this New York power plant
New York has 46 oil-fired plants in this category, and South Hampton in Southampton, Suffolk County, ranks #22 of 46 by 2024 electricity produced. It is a standby plant, meaning it sits ready for times when the grid needs extra help rather than running day in and day out.
The plant is owned by National Grid Generation LLC and began operating in 1963. It has one generator that burns distillate fuel oil, a light liquid fuel similar to heating oil, and it can supply up to 11.5 MW, a measure of the most power it can deliver at one moment. Its value is being available when called upon.
