Harvesting the sun's energy

With 64 MW of peak power, Usya is the third large photovoltaic plant that ACCIONA has built in the Atacama desert, one of the places with the highest solar radiation in the planet.

Located in the Calama commune, Antofagasta region, the Usya plant annually generate emission-free energy estimated at 146 gigawatt hours (GWh), equivalent to the electricity demand of some 70,000 Chilean homes.


The new photovoltaic installation has 187,200 modules installed on fixed structures, covering an area of some 105 hectares.


Around 400 people have worked in the phase of greatest construction activity of the project. After its entry into operation, the new plant avoids the annual emission of about 141,000 equivalent tons in coal plants.
