~78,840 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

18,378passenger cars driven for a year
10,282homes' yearly energy use
1,314,000tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 30% load factor × a typical oil emission factor (~750 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 oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a subtropical highland climate (Köppen Cwb) — Southern Hemisphere, latitude 18.8°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 88% 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.
