A solar-plus-storage project combining 300kW of PV and a 2MWh battery energy storage system (BESS) has been installed in the Polynesian archipelago nation of Tonga.

The first utility-scale battery project in Tonga officially opened today at an event attended by the South Pacific Kingdom’s prime minister.

French renewable power producer and developer Akuo Energy has commissioned a 29.2MWh battery energy storage system (BESS) in Tonga, several weeks after powering up a 19MWh project in Martinique.
