Acciona finishes in Chile the biggest PV plant in Latin America

Acciona Energía has begun the start-up phase of the ‘El Romero Solar’ photovoltaic solar plant, the biggest in Latin America with a maximum capacity of 246 MWp (196 MW rated power), just thirteen months after starting construction work. The company has also completed the assembly of the last sets of panels in the plant: 776,000 photovoltaic modules with a solar capture surface area of more than 1.5 million m2.

Located in the region of Atacama, Chile, the plant – 100% owned by Acciona – has already been connected to the Central Interconnected System (SIC) of that country, starting a process that will continue over the next weeks until the whole installation enters commercial service.


El Romero Solar is located in the municipality of Vallenar, around 645 km north of Santiago, with a surface area of 280 hectares in the Atacama Desert. It represents an investment of around 343 million dollars for Acciona. Once completed, it will produce around 500 GWh of clean energy per year, equivalent to the electricity demand of 240,000 Chilean homes, and avoid the emission of around 475,000 metric tons of CO2 from coal-fired power stations in the process.
