Gas power plant in Arizona, United States of America. Approximate location 31.3635, -110.9313.

GasArizonaUnited States of AmericaCO₂ reported

Valencia is a 108 MW gas power station in Arizona, United States of America. It is operated by UNS Electric Inc. Based on reported annual generation of 27 GWh, it can supply roughly 7,828 homes. It ranks #1838 of 9,833 United States of America power plants by installed capacity. Commissioned in 1997, it is around 29 years old — long-established. Its measured emissions of 78,468 t CO₂/yr (Climate TRACE) are equivalent to about 18,291 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 31.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 52% 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: 28/100 — 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).
