Two battery energy storage systems (BESS) developments from FRV Australia and AGL Energy, totalling 2,200MWh, have reached major milestones in Australia.
FRV Australia achieves grid connection for 200MWh Terang grid-forming BESS
FRV Australia connected its first battery energy storage system project to the grid, marking the energisation of the 100MW/200MWh Terang BESS in southwestern Victoria.
The project represents a major milestone for the company’s expansion into Australia’s energy storage sector and contributes to grid stabilisation efforts in the National Electricity Market (NEM).
The facility utilises intelligent algorithms to optimise performance while reducing demand peaks and supporting the transition toward a more sustainable electricity grid. Construction of the Terang BESS has reached near completion, with the project now entering the commissioning phase following successful grid connection.

Canadian Solar subsidiary e-STORAGE supplied the battery storage system for the Terang BESS, which marks FRV Australia’s first standalone storage project. The project will also benefit from Fluence’s Mosaic software optimisation for the 200MWh grid-forming BESS, enhancing operational efficiency and grid support capabilities.
The facility’s grid-forming capabilities enable it to provide essential system services while supporting grid stability during periods of high renewable energy penetration.
AGL commences construction on 500MW Tomago Battery Project
Meanwhile, AGL has commenced construction on its 500MW Tomago Battery Project in New South Wales following a groundbreaking ceremony attended by AGL CEO and managing director Damien Nicks, and chief operations and construction officer Matthew Currie.
Federal minister for climate change and energy Chris Bowen and the New South Wales minister for the Hunter Yasmin Catley also attended the ceremony alongside media representatives, local council members, community stakeholders and project partners.
The AU$800 million (US$516 million) grid-scale battery storage system, targeting operations in the second half of 2027, represents one of Australia’s largest BESS developments with 2,000MWh capacity designed to strengthen the state’s energy infrastructure.
AGL plans to begin operations at the Tomago Battery Project in the second half of 2027.
Fluence secured its biggest global contract for the 2,000MWh grid-forming battery energy storage system. Fluence said it would supply its Gridstack Pro for the utility-scale energy storage project.
Fluence launched the Gridstack series in 2020 and Gridstack Pro followed in 2023, which Fluence said at the time was aimed at the largest and most complicated projects its customers are undertaking.
Fluence has been contracted to construct the project and provide ongoing service and maintenance.
AGL previously secured regulatory approval for the 2,000MWh BESS development in November 2024, clearing the path for construction to commence.
The total construction cost of this grid-forming battery storage project is estimated to be approximately AU$800 million. Much like the Terang BESS, the Tomago Battery project will connect to the NEM.
AGL also has a target to add 12GW of renewables and firming to its portfolio by 2035.
