Solar power plant in Ontario, Canada. Approximate location 43.9294, -78.5454.

SolarOntarioCanadaPV

HPG Site A is a 2 MW solar power plant in Ontario, Canada. It is operated by Potentia Solar 14 LP. Based on its capacity (estimated), it can supply roughly 850 homes (estimated). It ranks #1122 of 1,211 Canada power plants by installed capacity. Commissioned in 2016, it is around 10 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 1.6% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

In context: how this plant compares

At 2 MW, HPG Site A is below the median solar plant in Canada (10 MW). Technically it is described as PV. Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.

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

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 43.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 59% 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: 83/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (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

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 thermal cycling 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.
