Baixada Fluminense

Gas power plant in Rio de Janeiro, Brazil. Approximate location -22.723437, -43.642327.

GasRio de JaneiroBrazilCCGT · HRSGCO₂ modelled

Baixada Fluminense is a 530 MW gas power station in Rio de Janeiro, Brazil. It is operated by Petróleo Brasileiro SA. Based on its capacity (estimated), it can supply roughly 597k homes (estimated). It ranks #93 of 2,572 Brazil power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. Its modelled annual emissions are 639,010 t CO₂/yr (Climate TRACE), equivalent to about 149k cars driven for a year. In context, gas supplies about 7.3% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

In context: how this plant compares

At 530 MW, Baixada Fluminense is well above the median gas plant in Brazil (100 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

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

~639,010 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

149kpassenger cars driven for a year
83khomes' yearly energy use
11 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 22.7°S — which shapes how much energy it can produce and how its output varies through the year.

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.

A gas turbine here also runs ~6% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

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

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.
