GasIndianaUnited States of America

Gary Works is a 161 MW gas power station in Indiana, United States of America. It is operated by United States Steel-Gary. Based on reported annual generation of 1,233 GWh, it can supply roughly 352,171 homes. It ranks #1460 of 9,833 United States of America power plants by installed capacity. Commissioned in 1997, it is around 29 years old — long-established. 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 facility's annual emissions are roughly equivalent to:

114,928passenger cars driven for a year
64,298homes' yearly energy use
8,217,333tree seedlings grown 10 years to absorb it

Estimated, not measured: from reported annual generation × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 41.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 34% 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: 71/100 — this site sits in the top 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 ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
