Mira Loma Peaker

Gas power plant in California, United States of America. Approximate location 34.0053, -117.5604.

GasCaliforniaUnited States of AmericaCO₂ reported

Mira Loma Peaker is a 50 MW gas power plant in California, United States of America. It is operated by Southern California Edison Co. Based on reported annual generation of 17 GWh, it can supply roughly 4,742 homes. It ranks #2777 of 9,833 United States of America power plants by installed capacity. Commissioned in 2007, it is around 19 years old — relatively modern. Its measured emissions of 5,491 t CO₂/yr (Climate TRACE) are equivalent to about 1,280 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 34.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 70% 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: 24/100 — 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 ~2% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
