HydroQuebecCanada

Lac-Robertson is a 22 MW hydro power plant in Quebec, Canada. It is operated by Hydro-Québec. Based on its capacity (estimated), it can supply roughly 22,025 homes (estimated). It ranks #507 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).

Local climate & thermal context

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 51.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 148% 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: 98/100 — 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.
