Geramar II (Antiga Tocantinópolis) power station is a 165.3 MW oil power station in Maranhão, Brazil. It is operated by Eneva SA [50%]; Geradora de Energia do Maranhão SA [50%]. Based on its capacity (estimated), it can supply roughly 124k homes (estimated). It ranks #226 of 2,572 Brazil power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. In context, oil supplies about 1.7% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

At 165.3 MW, Geramar II (Antiga Tocantinópolis) power station is well above the median oil plant in Brazil (2.4 MW). Technically it is described as Engine. 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 3.6°S — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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 corrosive environment (estimated ISO 9223 class C4 — High), 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 #23 largest oil power plant of 645 in Brazil by capacity.
Brazil has 645 oil power plants in this dataset, together about 11,544 MW of capacity.
