Atlântica IV — Brazil

Atlântica IV is a 30 MW wind power plant in Rio Grande do Sul, Brazil. Based on its capacity (estimated), it can supply roughly 26k homes (estimated). It ranks #609 of 2,572 Brazil power plants by installed capacity. Commissioned in 2014, it is around 12 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).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 120 MW for Atlântica wind farm, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares

At 30 MW, Atlântica IV is well above the median wind plant in Brazil (27.2 MW). 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

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 30.3°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 86% 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: 19/100 — 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.

Site climate & environmental severity

This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

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.
