Solvay Chalampe power station is a 20 MW gas power plant in Grand Est, France. It is operated by Solvay NV [100%]. Based on its capacity (estimated), it can supply roughly 23k homes (estimated). It ranks #364 of 2,216 France power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its annual emissions of 215,987 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 50k cars driven for a year. In context, gas supplies about 3.0% of France's electricity; the national grid averages 41 gCO₂/kWh (94.9% low-carbon) (2025).

In context: how this plant compares
At 20 MW, Solvay Chalampe power station is below the median gas plant in France (87.2 MW). Technically it is described as OCGT. 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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 47.8°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 20% 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: 61/100 — 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 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.
