Scotford Air Liquide — Canada

Scotford Air Liquide is a 80 MW gas power plant in Alberta, Canada. It is operated by ATCO. Based on its capacity (estimated), it can supply roughly 90k homes (estimated). It ranks #328 of 1,210 Canada power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. In context, gas supplies about 17.8% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

In context: how this plant compares

At 80 MW, Scotford Air Liquide is below the median gas plant in Canada (170 MW). 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.

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 warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 53.8°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 132% 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: 97/100 — this site sits in the top 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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling 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.
