As of 2023, Cerro Pabellón is the only geothermal power plant in the country, the first in South America, and the highest-altitude plant of its kind in the world, at 4,500 metres above sea level. The facility, inaugurated in September 2017, is located in the Atacama Desert, in the Ollagüe district of Antofagasta Region. It is composed of two units with a gross installed capacity of 24 MW each, for a total capacity of 48 MW; a third, 33 MW unit will be built. It will be able to produce around 340 GWh per year once fully operational. Cerro Pabellón is owned by Geotérmica del Norte, a joint venture between Enel Green Power Chile —the local unit of the Italian corporation Enel— and Chilean state-owned oil and gas company Enap.
