Metlen Energy & Metals, the Greek industrial and energy group formerly known as Mytilineos, has inaugurated its 89-MW Dona Antonia solar farm in Chile’s Coquimbo region.
Dona Antonia Solar Farm Powers 77,000 Homes
Located on a 200-hectare private plot 14 kilometers north of Ovalle, the Dona Antonia solar farm is part of the Pro-Growth project portfolio for the Coquimbo Region. Equipped with 151,920 solar panels, it has the production capacity to power approximately 77,000 homes.

“This is our second park in Chile. We are making a huge contribution to the energy transition in the region and the country. The radiation conditions are exceptional in this area, with a robust transmission system and the willingness of the communities and authorities, which has allowed us to promote the local economy and foreign investment,” said Juan Pablo Toledo, Metlen country manager.
Construction on the project began in 2023, employing an average of over 400 workers. By the end of 2025, energy storage batteries will be added to optimize energy use by storing power generated during daylight hours.
“Chile is our platform for growth in Latin America and Doña Antonia is also an example of how we connect and work in coordination with local communities, to contribute to the sustainable development of the locations where we are present. Through the development of clean energy and adding the use of batteries, we will be able to inject more reliable energy into the system, avoiding inefficiencies.”
Metlen Invests $65 Million in Dona Antonia Project
Metlen invested USD 65 million (EUR 59.5 million) in the Dona Antonia project, which is the second of four solar projects in the company’s 588-MWp build-to-own portfolio in Chile.
The addition of Doña Antonia Park to the National Electric System brings the Coquimbo Region’s total to 61 photovoltaic projects with an installed capacity of 602 MW. As the largest park in the Limarí province north of Ovalle, it is the second of four Metlen facilities in Chile that will collectively contribute nearly 600 MW of clean energy.
Metlen’s $460 Million Solar Portfolio
Doña Antonia is one of four Metlen projects in Chile, representing a total investment of US$460 million. The portfolio includes the Willka project (109.2 MW), inaugurated last December, along with the Tocopilla park (227 MW) in María Elena and the Tamarico park (167 MW) in Vallenar—both scheduled to come online in 2024. All four solar farms have a power purchase agreement (PPA) with the Chilean utility Enel Generacion Chile.
