Porsud I power station is a 115.9 MW gas power station in Rio de Janeiro, Brazil. It is operated by Karpowership Brasil Energia Ltda. Based on its capacity (estimated), it can supply roughly 131k homes (estimated). It ranks #288 of 2,572 Brazil power plants by installed capacity. Commissioned in 2022, it is around 4 years old — recently built. Its modelled annual emissions are 197,070 t CO₂/yr (Climate TRACE), equivalent to about 46k 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).

At 115.9 MW, Porsud I power station is well above the median gas plant in Brazil (100.2 MW). Technically it is described as Engine. 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.

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 22.9°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.
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.
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.
