The El Romero project included the installation of 60 ABB PVS800-IS inverter stations, each rated at 3.6MW. These inverters are plug-and-play solutions that are designed for multi-MW PV power stations.

Covering 280 hectares of land, the El Romero solar plant is reportedly the largest PV project of its kind in Latin America. The installation generates 493 GWh of clean energy per year — the electrical demand equivalent of 240,000 homes.

Alfredo Diez-Hochleitner, ABB’s product marketing director for solar in Spain, said: “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. We are proud of our ongoing investment in energy efficient solar technology that can operate in the most challenging environments, together with our ability to work closely with our partners to develop bespoke solutions, which has created an outstanding solar plant for the future.”
