Global Power Generation selects Hithium to supply 421 MWh BESS for Fraser Coast solar-plus-storage project in Australia

Type: Supply Agreement · Technology: Hybrid · Country: Australia · Capacity: 421 MWh · Announced: 2026-08-12

Global Power Generation (GPG), a unit of Spain’s NATURGY Group, awarded a supply contract to China’s Hithium for a 421 MWh battery energy storage system (BESS) as part of the Fraser Coast hybrid solar-plus-storage project in Queensland, Australia. The BESS will consist of 84 liquid-cooled units with grid-forming capabilities and will be AC-coupled to the 33kV switchgear of a 330 MW solar PV plant, enabling charging from both the solar plant and the grid. The system will provide energy arbitrage and Frequency Control Ancillary Services (FCAS) for grid support, with an expected operational flexibility to generate additional revenues. This marks Hithium’s first agreement with GPG, though the supplier already has multiple active projects in Australia’s expanding battery storage market. GPG operates nearly 19 GW of renewable and fossil-based generation globally, with NATURGY owning 75% of GPG and Kuwait Investment Authority holding the remaining 25%.
