Lumea, part of the Transgrid Group, and AGL have marked a significant milestone in the construction of the Liddell Battery Energy Storage System (BESS) in New South Wales. The project has received two 330/33kV transformers, each weighing 254 tonnes, transported from the Port of Newcastle to Muswellbrook.

The 500MW, two-hour duration BESS is being developed at the former Liddell Power Station site in the Hunter region. It is designed to store excess renewable energy and deliver grid stability by dispatching stored energy during peak demand periods.

Craig Stallan, Executive General Manager at Lumea, emphasized the importance of the transformers in enabling the battery to safely connect to the grid and support the increasing share of renewables in NSW. The project currently employs approximately 147 people, with first operations targeted for early 2026.

Johan Myburgh, General Manager of Construction at AGL, noted steady progress and the critical role the battery will play in delivering clean, reliable power for the state.

Lumea is providing end-to-end support including design, delivery, and commissioning of grid connection infrastructure, working closely with the Australian Energy Market Operator (AEMO) and AGL.

Once operational, the Liddell BESS will contribute significantly to a cleaner and more resilient energy future in New South Wales.
