Detailed engineering Gathering System

Built by Geotérmica del Norte – GDN, a joint venture between Enel Green Power Chile and ENAP, the plant, which uses high enthaly technology to binary cycle, is the only operational geothermal power plant in South America and the highest altitude of its kind in the world, as it is located at 4,500 meters above sea level.

This plant has two units of installed capacity 24 MW each for a total of 48 MW of capacity and currently Enel is developing the 3rd part of the project, which is the installation of a third unit. In full operation, Cerro Pabellón is expected to be able to produce around 340 GWh per year, which is equivalent to the annual consumption needs of more than 165,000 Chilean households, avoiding the emission into the atmosphere of more than 166,000 tons of CO2 each year.

Pares&Alvarez developed the detailed engineering Gathering System of Cerro Pabellón 3, with scope of the disciplines civil structural, electrical and instrumental and control. The third unit is expected to start operation in 2021, as reported by Enel Greenpower website.
