A consortium formed by Acciona and Abengoa has signed the contract to complete the construction of the Cerro Dominador concentrated solar power (CSP) plant in Chile. The consortium, led by AccionaIndustrial with a 51% stake, will be responsible for building the 110 MW CSP plant with Abengoa technology, making it the first in Latin America.

The CSP plant tower will join the 100 MW photovoltaic plant already in operation, built by Abengoa, which has been in commercial service since February 2018. It will be part of a renewable energy complex with a total capacity of 210 MW and the first to combine both technologies anywhere on the continent.

This project will be able to generate clean energy, manageable for 24 hours, with a 17.5 hour thermal storage capacity based on molten salts. The 146-hectare solar field has 10,600 heliostats that direct solar radiation to a receiver located at a height of 252 metres.

Work is expected to resume this month, with Cerro Dominador, a company owned by funds managed by EIG Global Energy Partners, securing project financing in May with a consortium of national and international banks, and with the Acciona Industrial and Abengoa consortium receiving the notice to proceed.

The Cerro Dominador complex is located in the town of María Elena, in the Atacama Desert, in the Region of Antofagasta, an area with one of the highest solar radiation indexes in the world. The CSP plant to be built by Acciona and Abengoa will produce clean energy and prevent the emission of 640,000 tonnes of CO2 into the atmosphere each year. The complex will prevent the emission of a total of 870,000 tonnes of carbon dioxide annually, and will supply clean energy through 15-year energy purchase agreements signed with distributors in 2014.

Construction of the Cerro Dominador CSP plant will make a significant contribution to the local economy, creating more than 1,000 jobs in the area during the construction peak, with priority given to residents from the region’s municipalities.

Cerro Dominador selected the Acciona Industrial and Abengoa consortium because of its proven experience of developing and executing solar thermal projects around the world.

Acciona has built 10 solar thermal power plants globally, with a total capacity of 624 MW. The 100 MW Kathu plant, in South Africa is currently under construction. Cerro Dominador is the fifth solar thermal power plant built by the company outside of Spain.

Abengoa will be the technology partner for the engineering and construction project, contributing its know-how in the construction of CSP plants, with over 30 years of experience developing and constructing plants with an installed power of 2.6 GW around the world, currently representing 38% of the global installed capacity. It is currently the technology partner for construction of phase IV of the Mohammed bin Rashid Al Maktoum Solar Park, owned by the Dubai Electricity and Water Authority (DEWA), the world’s largest solar complex, located in Dubai.
