GreenPoint Energy and Gunvor Group have signed a long‑term offtake agreement that secures revenue for the Koolunga battery energy storage system. The battery, to be built near Brinkworth in South Australia, will provide 200 MW of storage capacity and up to 800 MWh of discharge capability. Construction is slated to begin soon with commissioning expected in early 2028, and the facility will connect to the grid via a 275 kV transmission line at the Brinkworth Substation. The deal gives Gunvor a firm renewable power product to supply AI‑focused data centre operator Firmus Technologies, supporting the growing demand for reliable, firmed electricity in the digital infrastructure sector.
