Jesus Soares Pereira (Antiga Vale do Açú) — Brazil

Jesus Soares Pereira (Antiga Vale do Açú) is a 323 MW gas power station in Rio Grande do Norte, Brazil. It is operated by Petróleo Brasileiro SA. Based on its capacity (estimated), it can supply roughly 364k homes (estimated). It ranks #147 of 2,572 Brazil power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. Its modelled annual emissions are 549,240 t CO₂/yr (Climate TRACE), equivalent to about 128k 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 323 MW, Jesus Soares Pereira (Antiga Vale do Açú) is well above the median gas plant in Brazil (100.2 MW). Technically it is described as OCGT. 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.

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 hot semi-arid steppe climate (Köppen BSh) — Southern Hemisphere, latitude 5.4°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 ~8% 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

This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

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.
