Solar power plant in Artigas, Uruguay. Approximate location -30.4214, -57.4574.
SolarArtigasUruguay
ALTO CIELO is a 20 MW solar power plant in Artigas, Uruguay. Based on its capacity (estimated), it can supply roughly 8,509 homes (estimated). It ranks #34 of 73 Uruguay power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 5.1% of Uruguay's electricity; the national grid averages 80 gCO₂/kWh (97.8% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 30.4°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 79% 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: 21/100 — 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 0.3% at warm-season highs here (estimate).
