Hydro power plant in Alaska, Canada. Approximate location 52.9345, -132.1282.
HydroAlaskaCanada
Moresby Lake is a 6 MW hydro power plant in Alaska, Canada. It is operated by Atlantic Power Corp. Based on its capacity (estimated), it can supply roughly 6,006 homes (estimated). It ranks #879 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 subpolar oceanic climate (Köppen Cfc) — Northern Hemisphere, latitude 52.9°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 69% 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.
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.
