The turnkey project (EPC) is developed by a consortium led by the industrial company, in which Abengoa participates.

it’s about the first solar thermal power plant built in Latin America, more precisely in the town of María Elena, in the Atacama Desert, Chile, an area with one of the highest rates of solar radiation on the planet.

Cerro Dominador is a project of EIG Global Energy Partners. The technology to be used is thermal solar energy of the tower, which will reach a power of 110 MW.

You will work on an area of ​​approximately 146 hectares and will have 10,600 heliostats which will direct solar radiation to a receiver 252 meters high.

The solar energy of the thermal tower makes it possible to achieve a better efficiency relative to the parabolic hollow by reducing the path of the heat transfer fluid, the latter being molten salts.

The project will enable the production of clean energy in a manageable manner during 24 hours and will have a thermal storage capacity in molten salts of 17.5 hours.

Cerro Dominador will be able to avoid the emission of 640,000 tonnes of CO2 per year.

The creation of more than 1000 jobs in the area at its peak of construction to which the inhabitants of the municipalities of the region will have access in the first place.
