GasCaliforniaUnited States of AmericaCO₂ reported

Cymric 31X Cogen is a 7 MW gas power plant in California, United States of America. It is operated by Chevron USA Inc. Based on reported annual generation of 45 GWh, it can supply roughly 12,800 homes. It ranks #5177 of 9,833 United States of America power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. Its measured emissions of 18,021 t CO₂/yr (Climate TRACE) are equivalent to about 4,201 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 35.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 48% 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 ~1% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
