HydroNew HampshireUnited States of America

S C Moore is a 191 MW hydro power station in New Hampshire, United States of America. It is operated by Great River Hydro LLC. Based on reported annual generation of 336 GWh, it can supply roughly 96,057 homes. It ranks #1326 of 9,833 United States of America power plants by installed capacity. Commissioned in 1957, it is around 69 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 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.

Heating degree-days here run 87% 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: 91/100 — 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.
