RWE Strengthens Australia Renewable Energy Portfolio with Commissioning Completion of Limondale Battery Storage System

RWE Strengthens Australia Renewable Energy Portfolio with Commissioning Completion of Limondale Battery Storage System

(IN BRIEF) RWE has received approval from the Australian Energy Market Operator and Transgrid to move the Limondale Battery Energy Storage System into full operations, making it Australia’s first eight-hour battery operating at full capacity and the longest-duration battery currently in service in the country. The 50 MW/400 MWh system, located beside RWE’s Limondale Solar Farm near Balranald in southern New South Wales, consists of 144 Tesla Megapacks and is registered to charge at 100 MW and discharge at 50 MW for more than eight hours. Following successful grid compliance and performance testing, the battery will help reduce network pressure during peak demand, improve grid flexibility and support a more secure electricity system. The project was developed in response to the New South Wales Government’s Electricity Infrastructure Roadmap and was the first to receive a Long Duration Storage Long-Term Energy Service Agreement under ASL’s first tender. RWE partnered with Tesla, Beon Energy Solutions, Lumea and Transgrid to deliver the project, which forms part of the company’s broader battery storage growth strategy across Australia, Europe and the United States.

(PRESS RELEASE) ESSEN, 27-May-2026 — /EuropaWire/ — RWE has received official approval to move the Limondale Battery Energy Storage System from commissioning into full commercial operations, marking a major milestone for long-duration energy storage in Australia.

The sign-off from the Australian Energy Market Operator and transmission network service provider Transgrid allows RWE to operate Australia’s first eight-hour battery energy storage system at full capacity. Located near Balranald in southern New South Wales, the Limondale BESS is currently the longest-duration battery operating in Australia.

The 50-megawatt/400-megawatt hour battery system consists of 144 Tesla Megapacks. It is uniquely registered to charge at 100 megawatts and discharge at 50 megawatts, enabling it to deliver its registered maximum discharge output for more than eight hours. This gives the project a storage capacity of at least 400 megawatt hours.

Following commissioning, Limondale BESS successfully completed grid compliance and performance testing, demonstrating its ability to operate safely and reliably at maximum capacity. The battery is located next to RWE’s Limondale Solar Farm and is designed to help reduce network pressures during periods of peak electricity demand, supporting a more flexible, secure and resilient power system.

Sopna Sury, CEO of RWE Renewables Europe & Australia, said RWE is proud to deliver Limondale BESS, describing the project as a groundbreaking development for battery storage in Australia. She noted that the system marks a significant step in the growth of long-duration energy storage and will help strengthen grid stability, support secure energy supply and enable more efficient use of renewable energy.

Sury also thanked the RWE team, project partners, the New South Wales government and AEMO for their collaboration in bringing the project safely into operation.

The project was sized for eight hours in response to the New South Wales Government’s Electricity Infrastructure Roadmap. It was also the first project to receive a Long Duration Storage Long-Term Energy Service Agreement under the first tender conducted by ASL, a subsidiary of AEMO. The award highlighted the importance of early investment in long-duration storage projects and recognised Limondale BESS as a key asset supporting the state’s energy transition and the integration of renewable energy sources.

RWE worked with Tesla, Beon Energy Solutions, Lumea and Transgrid to deliver the project.

Australia is one of RWE’s focus markets, and the company has been active in the country since 2013. In 2021, RWE commissioned the Limondale Solar Farm in Balranald, New South Wales. The 314 MWac solar farm comprises 872,000 panels and produces enough electricity to supply around 105,000 homes each year.

RWE’s Australian team is developing a wider portfolio of wind, solar and battery storage projects across the country, supported by the company’s global renewable energy expertise. The company’s Theodore Wind Farm in Queensland, planned with a capacity of around 1 GW, has received Development Approval and is progressing through the federal EPBC process.

Globally, RWE develops, builds and operates battery storage systems across the United States, Europe and Australia. The company currently operates battery storage systems with a total capacity of 1.7 GW, with a further approximately 2.5 GW under construction. Battery storage remains an important part of RWE’s growth strategy as the company plans to significantly expand its storage capacity worldwide.
