Jupiá (Eng° Souza Dias) — Brazil

Jupiá (Eng° Souza Dias) is a 1,551.2 MW hydro power station in Mato Grosso do Sul, Brazil. It is operated by CTG Brasil [100%]. Based on its capacity (estimated), it can supply roughly 1.6 million homes (estimated). It ranks #29 of 2,572 Brazil power plants by installed capacity. Commissioned in 1969, it is around 57 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 51.8% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

In context: how this plant compares

At 1,551.2 MW, Jupiá (Eng° Souza Dias) is well above the median hydro plant in Brazil (11.5 MW). Technically it is described as run-of-river. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

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

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 20.8°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.
