Wolfskill Energy Center

Gas power plant in California, United States of America. Approximate location 38.2285, -122.0752.

GasCaliforniaUnited States of AmericaCO₂ reported

Wolfskill Energy Center is a 47 MW gas power plant in California, United States of America. It is operated by Gilroy Energy Center LLC. Based on reported annual generation of 7 GWh, it can supply roughly 2,000 homes. It ranks #2855 of 9,833 United States of America power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. Its measured emissions of 3,471 t CO₂/yr (Climate TRACE) are equivalent to about 809 cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 38.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 47% 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: 30/100 — this site sits in the bottom 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.

A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
