Hydro power plant in Quebec, Canada. Approximate location 53.7323, -78.5712.
HydroQuebecCanada
La Grande-1 is a 1,436 MW hydro power station in Quebec, Canada. It is operated by Hydro-Québec. Based on its capacity (estimated), it can supply roughly 1,437,641 homes (estimated). It ranks #18 of 1,159 Canada power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 52.8% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 53.7°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 202% 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: 100/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #12 largest hydro power plant of 556 in Canada by capacity.
Canada has 556 hydro power plants in this dataset, together about 80,683 MW of capacity.
