Steven's Croft — United Kingdom

Steven's Croft is a 50 MW cogeneration power plant in Scotland, United Kingdom. It is operated by E.ON (formerly Powergen). Based on its capacity (estimated), it can supply roughly 63k homes (estimated). It ranks #254 of 2,860 United Kingdom power plants by installed capacity. Its annual emissions of 396,862 t CO₂/yr (EU ETS) are equivalent to about 93k cars driven for a year. In context, the national grid averages 217 gCO₂/kWh (64.4% low-carbon) (2025).

Local climate & thermal context

This cogeneration plant produces electricity and useful heat together for higher fuel efficiency. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 55.2°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 42% 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: 76/100 — this site sits in the top third of the power plants we cover by heating degree-days.

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 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.
