OtherRio de JaneiroBrazilCO₂ reported
GNA I power station is a 1,330 MW other power station in Rio de Janeiro, Brazil. It is operated by SPIC Brasil SA. Based on its capacity (estimated), it can supply roughly 998,640 homes (estimated). It ranks #21 of 2,549 Brazil power plants by installed capacity. Its measured emissions of 1,259,744 t CO₂/yr (Climate TRACE) are equivalent to about 293,647 cars driven for a year. In context, the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

This other plant generates electricity for the grid. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 21.8°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 100% 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: 13/100 — 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.
