WILLIAM ARJONA — Brazil

WILLIAM ARJONA is a 190 MW gas power station in Mato Grosso do Sul, Brazil. Based on its capacity (estimated), it can supply roughly 214k homes (estimated). It ranks #206 of 2,572 Brazil power plants by installed capacity. Its modelled annual emissions are 323,090 t CO₂/yr (Climate TRACE), equivalent to about 75k 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 190 MW, WILLIAM ARJONA is well above the median gas plant in Brazil (100.2 MW). 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 tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 20.5°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.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
