Hydro power plant in Montana, United States of America. Approximate location 46.649, -111.7279.

HydroMontanaUnited States of America

Canyon Ferry is a 50 MW hydro power plant in Montana, United States of America. It is operated by U S Bureau of Reclamation. Based on reported annual generation of 369 GWh, it can supply roughly 105,400 homes. It ranks #2770 of 9,833 United States of America power plants by installed capacity. Commissioned in 1954, it is around 72 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 5.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 46.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 68% 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.
