Gas power plant in California, United States of America. Approximate location 39.1367, -121.6398.

GasCaliforniaUnited States of AmericaCO₂ reported

Yuba City Cogen Partners is a 49 MW gas power plant in California, United States of America. It is operated by Wellhead Energy LLC. Based on reported annual generation of 4 GWh, it can supply roughly 1,057 homes. It ranks #2805 of 9,833 United States of America power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. Its measured emissions of 72,508 t CO₂/yr (Climate TRACE) are equivalent to about 16,902 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 hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 39.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 51% 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: 29/100 — 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).
