GasArizonaUnited States of AmericaCO₂ reported

Sundance is a 605 MW gas power station in Arizona, United States of America. It is operated by Arizona Public Service Co. Based on reported annual generation of 303 GWh, it can supply roughly 86,628 homes. It ranks #613 of 9,833 United States of America power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its measured emissions of 287,951 t CO₂/yr (US EPA GHGRP) are equivalent to about 67,121 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 desert climate (Köppen BWh) — Northern Hemisphere, latitude 32.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 71% 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: 23/100 — 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 ~4% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
