CoalBuenos Aires F.D.Argentina

COSTANERA is a 1,982 MW coal power station in Buenos Aires F.D., Argentina. It is operated by ENDESA COSTANERA. Based on its capacity (estimated), it can supply roughly 2,480,581 homes (estimated). It ranks #1 of 236 Argentina power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. In context, coal supplies about 1.8% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:

2,023,785passenger cars driven for a year
1,132,243homes' yearly energy use
144,700,600tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 34.6°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 61% 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: 26/100 — 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.
