Chile Largest CSP Project in Pictures: Cerro Dominador [PV: 100 MW | CSP: 110 MW with 17.5 hours of storage]

5th September 2018

Cerro Dominador Project is located near the city of Calama in Northern Chile. It comprises a 100 MW CSP plant with 17.5 hours of thermal storage and a 100 MW PV Plant.

Overcoming initial difficulties, Cerro Dominador recently closed $758 million in financing. The project is expected to be operational in December 2019.

According to the developer, the project will generate 1500 jobs during construction and create opportunities for knowledge transfer.
