Roswell Solar LLC is a 70 MW solar power plant in New Mexico, United States of America. It is operated by Roswell Solar LLC. Based on reported annual generation of 164 GWh, it can supply roughly 47,000 homes. It ranks #2393 of 9,833 United States of America power plants by installed capacity. Commissioned in 2016, it is around 10 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).

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 33.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 27% 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: 39/100 — this site sits in the mid 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 0.7% at warm-season highs here (estimate).
