GasIdahoUnited States of AmericaCO₂ reported

Rathdrum Power LLC is a 302 MW gas power station in Idaho, United States of America. It is operated by Rathdrum Operating Services Co. Inc.. Based on reported annual generation of 1,801 GWh, it can supply roughly 514,685 homes. It ranks #941 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 695,632 t CO₂/yr (US EPA GHGRP) are equivalent to about 162,152 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).

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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 47.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 49% 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: 79/100 — 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).
