Tambaqui power station — Brazil

Tambaqui power station is a 143.3 MW other power station in Amazonas, Brazil. It is operated by Âmbar Energia SA. Based on its capacity (estimated), it can supply roughly 108k homes (estimated). It ranks #246 of 2,572 Brazil power plants by installed capacity. Its modelled annual emissions are 331,270 t CO₂/yr (Climate TRACE), equivalent to about 77k cars driven for a year. In context, the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

Local climate & thermal context

This other plant generates electricity for the grid. It sits in a tropical monsoon climate (Köppen Am) — Southern Hemisphere, latitude 3.1°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.

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.
