When added to the site’s existing 10.2MWac/12.9MWh BESS, the augmentation will bring the total on-site battery storage system to 15MWac/32.7MWh.

The original Palau Solar project was inaugurated in June 2023 as the largest solar-plus-storage facility in the Western Pacific at the time, pairing a 15.28MWp solar PV facility with the 12.9MWh BESS under a long-term power supply agreement with PPUC.

Located on Babeldaob, Palau’s largest island, the US$29 million project was designed to supply around a quarter of the country’s electricity demand and to contribute to Palau’s nationally determined contribution under the Paris Agreement.

The AIFFP provided the initial financing for the project, a US$18 million loan and US$4 million grant extended to SPPP, and is now backing its expansion.

The facility was developed with German EPC contractor Juwi Renewable Energies, with DNV serving as owner’s engineer, and uses First Solar PV modules, SAFT batteries and SMA inverters.
