Castle River is a 44 MW wind power plant in Alberta, Canada. It is operated by Vision Quest (TransAlta). Based on its capacity (estimated), it can supply roughly 37k homes (estimated). It ranks #446 of 1,211 Canada power plants by installed capacity. Commissioned in 1997, it is around 29 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 7.9% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

At 44 MW, Castle River is well above the median wind plant in Canada (24 MW). Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 49.5°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 100% 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: 94/100 — 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #94 largest wind power plant of 241 in Canada by capacity.
Canada has 241 wind power plants in this dataset, together about 12,127 MW of capacity.
