DIESEL ENAEX (CUMMINS-DEUTZ)

DIESEL ENAEX (CUMMINS-DEUTZ) is a 3 MW oil power plant in Antofagasta, Chile. It is operated by ENAEX. Based on its capacity (estimated), it can supply roughly 2,027 homes (estimated). It ranks #270 of 315 Chile power plants by installed capacity. In context, oil supplies about 0.6% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

~5,322 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

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 cold desert climate (Köppen BWk) — Southern Hemisphere, latitude 23.1°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 81% 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: 20/100 — 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.
