The system features grid-forming capabilities and will provide energy arbitrage and frequency control ancillary services (FCAS).

A larger hybrid development already under construction

The battery storage system forms part of GPG’s broader Fraser Coast Hybrid Project, which entered construction in July 2026 near the township of Brooweena, roughly 50km south-west of Maryborough.

The 330MW solar-plus-storage development is GPG’s largest renewable energy project in Australia, backed by more than €300 million (US$342 million) of investment and a ten-year power purchase agreement (PPA).

The project cleared federal environmental assessment under the Environment Protection and Biodiversity Conservation (EPBC) Act in late 2025, with commercial operations targeted for 2028 and grid connection via a 275kV line to Powerlink’s Teebar Substation.
