Rotterdam Capelle (RoCa) power station — Netherlands

Rotterdam Capelle (RoCa) power station is a 268 MW gas power station in Zuid-Holland, Netherlands. It is operated by Uniper SE [100%]. Based on its capacity (estimated), it can supply roughly 302k homes (estimated). It ranks #26 of 119 Netherlands power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. Its annual emissions of 139,467 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 33k cars driven for a year. In context, gas supplies about 34.9% of Netherlands's electricity; the national grid averages 254 gCO₂/kWh (54.2% low-carbon) (2025).

In context: how this plant compares

At 268 MW, Rotterdam Capelle (RoCa) power station is well above the median gas plant in Netherlands (120 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.

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 52.0°N — which shapes how much energy it can produce and how its output varies through the year.

Site climate & environmental severity

This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), 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.
