Gas power plant in Maryland, United States of America. Approximate location 39.0, -77.0939.
GasMarylandUnited States of AmericaCO₂ modelled
NIH Cogeneration Facility is a 28 MW gas power plant in Maryland, United States of America. It is operated by Power Choice/Pepco Energy Serv. Based on reported annual generation of 164 GWh, it can supply roughly 47k homes. It ranks #4324 of 10,884 United States of America power plants by installed capacity. Commissioned in 2018, it is around 8 years old — recently built. Its modelled annual emissions are 73,692 t CO₂/yr (Climate TRACE), equivalent to about 17k 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 28 MW, NIH Cogeneration Facility is below the median gas plant in United States of America (121.2 MW). 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 39.0°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 7% 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: 47/100 — this site sits in the mid 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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
