Gas power plant in Oregon, United States of America. Approximate location 42.1739, -121.8106.
GasOregonUnited States of AmericaCCGT · HRSGCO₂ measured
Klamath Cogeneration Plant is a 501.5 MW gas power station in Oregon, United States of America. It is operated by Klamath Energy LLC. Based on reported annual generation of 3,312 GWh, it can supply roughly 946k homes. It ranks #1218 of 10,884 United States of America power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its annual emissions of 100,828 t CO₂/yr (US EPA GHGRP) are equivalent to about 24k 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).

In context: how this plant compares
At 501.5 MW, Klamath Cogeneration Plant is well above the median gas plant in United States of America (121.2 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

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 42.2°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 44% 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: 77/100 — this site sits in the top third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
