ABB supplied central inverters to 246 MW Chilean solar plant


Swiss power electronics specialist ABB has confirmed that it suppled its central inverter solutions to the 246 MWp El Romero Solar Plant, located in Chile’s Atacama Desert and brought online in late 2016 by Spanish EPC Acciona.

Located 645 km north of Santiago, the El Romero PV plant is one of the largest in Latin America and sits in the driest region on the planet. These harsh conditions prompted Acciona to source an inverter solution developed with such dryness in mind.

ABB’s PVS800-IS inverter stations have low auxiliary power consumption and can be easily plugged into to a medium voltage transformer station. Inside each 3.6 MW inverter station are two to three central inverters, monitoring software and air filtration systems. Notably, the ABB SafePlus CCV Sf6 insulated compact switchgear and ABB power plant controller ensure continuous power supply to a local data center – critical for installations situated in such remote regions.

“The El Romero Solar Plant was a huge feat of engineering in hostile conditions, that saw ABB work closely with Acciona to install solar solutions that provide 100% of the data center’s clean energy,” said ABB’s product marketing director for solar in Spain, Alfredo Diez-Hochleitner.
