Solar power plant in Arizona, United States of America. Approximate location 32.9774, -113.4945.
SolarArizonaUnited States of America
Agua Caliente Solar Project is a 348 MW solar power station in Arizona, United States of America. It is operated by Agua Caliente Solar. Based on reported annual generation of 716 GWh, it can supply roughly 204,628 homes. It ranks #883 of 9,833 United States of America power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 8.6% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 33.0°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 81% 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: 20/100 — 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.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 3.3% at warm-season highs here (estimate).
