WindCaliforniaUnited States of America

Ridgetop is a 47 MW wind power plant in California, United States of America. It is operated by Terra-Gen Operating Co-Wind. Based on reported annual generation of 134 GWh, it can supply roughly 38,257 homes. It ranks #2857 of 9,833 United States of America power plants by installed capacity. Commissioned in 1994, it is around 32 years old — long-established. 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 35.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 29% below 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: 38/100 — 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.
