Acciona-Abengoa team to build Cerro Dominador solar thermal plant in Chile


A consortium formed by Spanish companies Abengoa and Acciona has signed a contract to complete the construction of the Cerro Dominador solar thermal plant in Chile.

As leader of the consortium, Acciona will have a 51% stake and be responsible for building the 110MW solar thermal plant with Abengoa technology.

Touted be the first of its kind in Latin America, the solar thermal plant will join the 100MW photovoltaic plant built by Abengoa, which has been in commercial operation since February 2018.

Both will form a renewable energy complex with a total capacity of 210MW and the first to combine both technologies in South America.

The project will generate clean energy and supply it 24 hours a day due to its thermal storage system. The 146-hectare solar field comprises 10,600 heliostats that will concentrate solar radiation onto a receiver located 252m high.

Work is expected to commence in July 2018 as Cerro Dominador, a company owned by funds managed by EIG Global Energy Partners, closed the financing of the project last May with a consortium of national and international banks and obtained the Notice to Proceed by the consortium.

The Cerro Dominador complex is located in the commune of MarĂ­a Elena, in the Atacama Desert, in the Antofagasta Region, which has one of the highest solar radiation rates in the world.

The clean energy produced by the solar thermal plant will prevent 640,000 tonnes of CO2 emissions per year. The complex will deliver clean energy through 15-year energy purchase agreements with distribution companies signed in 2014.

More than 1,000 jobs will be created during the peak of construction of the plant.

Abengoa will be the technological partner of the engineering and construction project.

Currently, the firm is the technology partner and participates in the construction of phase IV of the largest solar complex in the world in Dubai, the Mohammed bin Rashid Al Maktoum Solar Park, owned by Dubai Electricity and Water Authority (DEWA).
