ACCIONA Energía (Sarriguren, Spain) has begun the start-up phase of the ‘El Romero Solar’ solar photovoltaic (PV) plant, the biggest in Latin America with a maximum capacity of 246 MW (196 MW rated power), just thirteen months after starting construction work.

The company has also completed the assembly of the last sets of PV panels in the plant: 776,000 photovoltaic modules with a solar capture surface area of more than 1.5 million square meters.

Located in the region of Atacama, Chile, the PV 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.

500 GWh of solar power expected anually

It represents an investment of around USD 343 million for ACCIONA, the company notes. Once completed, it will produce around 500 GWh of solar power per year, equivalent to the electricity demand of 240,000 Chilean homes.

ACCIONA Energía Chile General Manager José Ignacio Escobar expressed his satisfaction at having completed the installation of the photovoltaic panels in the plant and its grid connection in just thirteen months, two less than the initial timescale contained in the construction plan.

In a recent tender in Mexico ACCIONA Energía was awarded 478 GWh, allowing it to build the Puerto Libertad photovoltaic complex in Sonora.
