Fluence and AGL sign deal to deliver the 500 MW / 2000 MWh Tomago Battery Energy Storage System in Australia

MELBOURNE, Australia, July 31, 2025 (GLOBE NEWSWIRE) — Fluence Energy, Inc. (“Fluence”) (NASDAQ: FLNC), a global market leader delivering intelligent energy storage, services, and asset optimization software, today announced that Fluence has been selected by AGL to deliver the 500 MW / 2000 MWh Tomago Battery Energy Storage System (BESS) in Newcastle, New South Wales, Australia. The deal is Fluence’s largest project transaction globally, one of the largest energy storage transactions by MWh in the Australian National Energy Market (NEM) to date, and marks 5 GWh of projects by Fluence in Australia.

The Tomago BESS will be the third grid-scale battery storage system Fluence will deliver for AGL, having completed the 50 MWh Broken Hill BESS and currently constructing the 1000 MWh Liddell BESS.

The Tomago BESS project will use Fluence’s Gridstack Pro™, a utility-scale energy storage product with optimized design and flexibility and will provide grid-forming capability to improve grid reliability. AGL has contracted Fluence to construct the project and provide ongoing service and maintenance.

“We are honored to be selected by AGL and partner with them on the Tomago BESS project. This project strongly demonstrates our ongoing commitment to support AGL in their ambitious plan to deploy large-scale battery storage systems for a renewable energy future across Australia. Australia remains one of the most important storage markets globally, experiencing significant growth as the country accelerates its transition to renewable energy sources,” said Jan Teichmann, SVP & President, APAC.

“Our team takes great pride in continuing our partnership with AGL to meet the challenges of Australia’s energy transition. The Tomago BESS is a testament to the strength of Fluence’s full scope project deployment expertise in Australia and the products we offer to this market,” said Jason Beer, General Manager, Fluence Australia.

“We are pleased to continue our partnership with Fluence as the battery energy storage provider for the Tomago Battery. This project builds on the work we have done together for AGL’s Broken Hill and Liddell batteries,” said AGL Chief Operating Officer, Markus Brokhof.

Fluence has a strong track record in Australia, with four storage systems currently in operation, another two expected to enter into operation in the next few months, and several BESS projects currently under construction.
