John S Rainey is a 1,102 MW gas power station in South Carolina, United States of America. It is operated by South Carolina Public Service Authority. Based on reported annual generation of 5,582 GWh, it can supply roughly 1,594,857 homes. It ranks #275 of 9,833 United States of America power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its measured emissions of 2,632,605 t CO₂/yr (US EPA GHGRP) are equivalent to about 613,661 cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.3°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 38% below 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: 35/100 — 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.
A gas turbine here also runs ~1% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
