Construction and commissioning are expected to take around 32 months, with the project intended to operate for approximately 25 years from a proposed start date of January 2028.
The referring entity is Hanworth BidCo Pty Ltd, acting as trustee for the Hanworth Bid Trust, with Octopus Australia holding an interest in the trust and Enervest managing development and approvals.
Octopus Australia is an energy fund manager and developer with a portfolio and pipeline exceeding AU$16 billion (US$11.52 billion) across wind, solar and battery storage projects in Australia.
As reported by Energy-Storage.news earlier this year, the company acquired the 4.8GWh battery storage project from Enervest. At the time, Octopus described it as Australia’s “largest planned BESS”.
The project is classified as State Significant Development (SSD) under New South Wales planning law, given its estimated capital investment of approximately AU$1.9 billion (US$1.24 billion), meaning the EPBC referral proceeds in parallel with a state-level environmental impact assessment.
