Iracema is a 14 MW biomass power plant in Sao Paulo, Brazil. It is operated by São Martinho SA. Based on its capacity (estimated), it can supply roughly 19k homes (estimated). It ranks #1227 of 2,572 Brazil power plants by installed capacity. Commissioned in 1905, it is around 121 years old — an older, legacy facility. In context, biomass 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 14 MW, Iracema is around 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 humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 22.6°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 97% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 15/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

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.
