GasIdahoUnited States of America
Evander Andrews Power Complex is a 271 MW gas power station in Idaho, United States of America. It is operated by Idaho Power Co. Based on reported annual generation of 295 GWh, it can supply roughly 84,228 homes. It ranks #1030 of 9,833 United States of America power plants by installed capacity. Commissioned in 2005, it is around 21 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).

This facility's annual emissions are roughly equivalent to:
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.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 43.2°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 26% 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: 66/100 — 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 ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #613 largest gas power plant of 1818 in United States of America by capacity.
United States of America has 1818 gas power plants in this dataset, together about 546,436 MW of capacity.
