Andes IIb, LATAM’s largest battery project. It is a 180 MWp PV+ESS and 116 MW/560 MWh ESSS project located in Calama, Antofagasta, Chile.
Andes Solar II B will be the most efficient solar farm in the world. Located in the Antofagasta Region, it integrates 180 MWp of PV and will have an integrated battery system providing 116 MW.
The 116 MW of batteries that, together with Fluence, will form part of this project, make it the largest battery storage system in Latin America, capable of supplying energy to the grid for 5 hours.
This initiative was the first solar farm in Chile to be integrated with lithium batteries using DC coupling technology supplied by eks Energy.
The project was built using our HybridSystem solution: AMPS and PPC technology from eks Energy; which allowed solar power to be injected into the system during the night.
Andes Solar IIb consists of a total of 46 AMPS using the latest tri-level technology, allowing voltages of 1550 Vdc at full power. In the medium voltage transformation stage, a 5600 kW transformer was used, allowing two AMPS to be connected to each other, reducing cost overruns.
