Sethelec D'Arles power station is a 44 MW gas power plant in Provence-Alpes-Côte d'Azur, France. It is operated by ENGIE SA [100%]. Based on its capacity (estimated), it can supply roughly 50k homes (estimated). It ranks #196 of 2,216 France power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its annual emissions of 305 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 71 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).

At 44 MW, Sethelec D'Arles 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.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 43.7°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #28 largest gas power plant of 34 in France by capacity.
France has 34 gas power plants in this dataset, together about 7,707 MW of capacity.
