WindIdahoUnited States of America

Hammett Hill Windfarm is a 23 MW wind power plant in Idaho, United States of America. It is operated by Aegis Renewables LLC. Based on reported annual generation of 52 GWh, it can supply roughly 14,771 homes. It ranks #3532 of 9,833 United States of America power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 10.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer Mediterranean continental climate (Köppen Dsb) — Northern Hemisphere, latitude 43.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 20% 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: 62/100 — this site sits in the mid 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.
