Cerro Chato I (Antiga Coxilha Negra V) is a 30 MW wind power plant in Rivera, Brazil. It is operated by CGT Eletrosul [100%]. Based on its capacity (estimated), it can supply roughly 26k homes (estimated). It ranks #638 of 2,572 Brazil power plants by installed capacity. Commissioned in 2012, it is around 14 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 15.7% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

At 30 MW, Cerro Chato I (Antiga Coxilha Negra V) is well above the median wind plant in Brazil (27 MW). Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 30.8°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 74% 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: 22/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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 #71 largest wind power plant of 412 in Brazil by capacity.
Brazil has 412 wind power plants in this dataset, together about 10,300 MW of capacity.
