Solar power plant in Ontario, Canada. Approximate location 44.2904, -76.9257.
SolarOntarioCanadaPV
First Light I is a 9 MW solar power plant in Ontario, Canada. It is operated by Sunedison / Skypower Ltd. Based on its capacity (estimated), it can supply roughly 3.9k homes (estimated). It ranks #816 of 1,211 Canada power plants by installed capacity. Commissioned in 2009, it is around 17 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).

At 9 MW, First Light I is around 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.

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 44.3°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 70% 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: 86/100 — 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.
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.
The #109 largest solar power plant of 143 in Canada by capacity.
Canada has 143 solar power plants in this dataset, together about 1,823 MW of capacity.
