OilNew YorkUnited States of AmericaCO₂ reported
Holtsville is a 567 MW oil power station in New York, United States of America. It is operated by National Grid Generation LLC. Based on reported annual generation of 20 GWh, it can supply roughly 5,628 homes. It ranks #660 of 9,833 United States of America power plants by installed capacity. Commissioned in 1974, it is around 52 years old — an older, legacy facility. Its measured emissions of 19,891 t CO₂/yr (US EPA GHGRP) are equivalent to about 4,637 cars driven for a year. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.8°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 15% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 58/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
