Geramar II (Antiga Nova Olinda)

Geramar II (Antiga Nova Olinda) is a 166 MW oil power station in Maranhao, Brazil. Based on its capacity (estimated), it can supply roughly 124,567 homes (estimated). It ranks #166 of 2,549 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).

~326,989 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

Estimated, not measured: from installed capacity at a typical 30% load factor × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

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 3.5°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 100% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
