Jemeppe-sur-Sambre power station — Belgium

Jemeppe-sur-Sambre power station is a 106 MW gas power station in Namur, Belgium. It is operated by Luminus NV/SA [100%]. Based on its capacity (estimated), it can supply roughly 119k homes (estimated). It ranks #36 of 95 Belgium power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. Its annual emissions of 70,278 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 16k cars driven for a year. In context, gas supplies about 21.5% of Belgium's electricity; the national grid averages 150 gCO₂/kWh (72.0% low-carbon) (2025).

In context: how this plant compares

At 106 MW, Jemeppe-sur-Sambre power station is below the median gas plant in Belgium (128 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Siemens Energy: SGT5-4000F. 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.

Climate zone & how it works

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 50.4°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).

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.
