Rupert Cogen Project — United States of America

Rupert Cogen Project is a retired gas power station in Idaho, United States of America. Its current lifecycle status is “Retired” — so it is not yet, or no longer, generating at full output. It ranks #5577 of 10,884 United States of America power plants by installed capacity. 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).

In context: how this plant compares

At 10.4 MW, Rupert Cogen Project is below the median gas plant in United States of America (121.2 MW). Its lifecycle status is Retired; it no longer generates electricity. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
