Stanlow Refinery power station — United Kingdom

Stanlow Refinery power station is a 200 MW gas power station in Cheshire West and Chester, United Kingdom. It is operated by Essar Oil (UK) Ltd. Based on its capacity (estimated), it can supply roughly 225k homes (estimated). It ranks #135 of 2,860 United Kingdom power plants by installed capacity. Commissioned in 2025, it is around 1 years old — recently built. In context, gas supplies about 31.1% of United Kingdom's electricity; the national grid averages 217 gCO₂/kWh (64.4% low-carbon) (2025).

In context: how this plant compares

At 200 MW, Stanlow Refinery power station is well above the median gas plant in United Kingdom (115 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

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 53.3°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 27% 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: 66/100 — 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 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.
