Solar power plant in Minnesota, United States of America. Approximate location 45.4936, -94.1134.
SolarMinnesotaUnited States of America
Hartmann Project CSG is a 1 MW solar power plant in Minnesota, United States of America. It is operated by Hartmann Community Solar LLC. Based on its capacity (estimated), it can supply roughly 425 homes (estimated). It ranks #9507 of 9,833 United States of America power plants by installed capacity. Commissioned in 2020, it is around 6 years old — recently built. 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 warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 45.5°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 82% above 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: 90/100 — this site sits in the top 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 0.0% at warm-season highs here (estimate).

The #3027 largest solar power plant of 3283 in United States of America by capacity.
United States of America has 3283 solar power plants in this dataset, together about 37,970 MW of capacity.
