Vale do Rosário

Biomass power plant in Sao Paulo, Brazil. Approximate location -20.6158, -48.0004.

BiomassSao PauloBrazil

Vale do Rosário is a 97 MW biomass power plant in Sao Paulo, Brazil. Based on its capacity (estimated), it can supply roughly 134k homes (estimated). It ranks #319 of 2,572 Brazil power plants by installed capacity. Commissioned in 1994, it is around 32 years old — long-established. In context, biomass supplies about 7.3% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

Data provenance

The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

In context: how this plant compares

At 97 MW, Vale do Rosário is well above the median biomass plant in Brazil (15 MW). Biomass plants burn organic material such as wood, residues or waste-derived fuel to raise steam; they are dispatchable and counted as low-carbon where the feedstock is sustainably sourced.

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

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 20.6°S — which shapes how much energy it can produce and how its output varies through the year.

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

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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
