Do Atlântico is a 490 MW oil power station in Rio de Janeiro, Brazil. It is operated by Ternium Brasil Ltda. Based on its capacity (estimated), it can supply roughly 368k homes (estimated). It ranks #101 of 2,572 Brazil power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. Its modelled annual emissions are 1,516,570 t CO₂/yr (Climate TRACE), equivalent to about 354k cars driven for a year. In context, oil supplies about 1.7% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

At 490 MW, Do Atlântico is well above the median oil plant in Brazil (2 MW). Technically it is described as OCGT. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 22.9°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
