GasNevadaUnited States of America

Harry Allen is a 745 MW gas power station in Nevada, United States of America. It is operated by Nevada Power Co. Based on reported annual generation of 3,378 GWh, it can supply roughly 965,257 homes. It ranks #463 of 9,833 United States of America power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. 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).

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 cold desert climate (Köppen BWk) — Northern Hemisphere, latitude 36.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 50% 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: 29/100 — this site sits in the bottom 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 ~3% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
