Cerro Dominador project is a 210MW hybrid concentrated solar power (CSP) and photovoltaic (PV) power complex under construction on a 1,000ha-site, approximately 60km away from Calama at Maria Elena in the Atacama Desert, Chile.
Construction on the $1.4bn project, which consists of a 100MW PV plant and 110MW CSP plant, was started in 2014.
The PV plant was commissioned in February 2018, while the Cerro Dominador CSP plant, the first solar thermal power project in Latin America, is expected to commence operation by the end of 2019.
