Solar power plant in Jujuy, Argentina. Approximate location -23.8, -66.8.
SolarJujuyArgentinaPV
Cauchari is a 300 MW solar power station in Jujuy, Argentina. It is operated by Jujuy Energía y Minería Sociedad Estado (JEMSE) [100%]. Based on its capacity (estimated), it can supply roughly 128k homes (estimated). It ranks #42 of 275 Argentina 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 3.4% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

At 300 MW, Cauchari is well above the median solar plant in Argentina (30 MW). Technically it is described as PV. Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a polar tundra climate (Köppen ET) — Southern Hemisphere, latitude 23.8°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 59% 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: 83/100 — this site sits in the top third of the power plants we cover by heating degree-days.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with heat / UV the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #1 largest solar power plant of 7 in Argentina by capacity.
Argentina has 7 solar power plants in this dataset, together about 540 MW of capacity.
