Sepé Tiaraju (Antiga Canoas)

Gas power plant in Rio Grande do Sul, Brazil. Approximate location -29.8724, -51.1374.

GasRio Grande do SulBrazilCO₂ reported

Sepé Tiaraju (Antiga Canoas) is a 249 MW gas power station in Rio Grande do Sul, Brazil. It is operated by Petróleo Brasileiro SA. Based on its capacity (estimated), it can supply roughly 279,994 homes (estimated). It ranks #115 of 2,549 Brazil power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its measured emissions of 51,133 t CO₂/yr (Climate TRACE) are equivalent to about 11,919 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).

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 humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 29.9°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 89% 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: 18/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

A gas turbine here also runs ~3% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
