Vena Energy has commenced construction on what will become one of the largest battery energy storage (BESS) systems in South Australia.
The 408 megawatt-hour (MWh) Tailem Bend 3 BESS will enhance grid stability and support the state’s transition to renewable energy and its goal of achieving net zero emissions by 2050.
Scheduled for commissioning in 2027, the project is Vena Energy’s third BESS project in Australia.
The development also marks the third phase of Vena Energy’s broader Tailem Bend energy precinct, following the delivery of the 127 MWdc Tailem Bend Solar Project in 2019 and the Tailem Bend 2 Hybrid Project, which added 118 MWdc of solar capacity in 2023 and a 41.5 MWh battery in 2024.
Owen Sela, Head of Australia at Vena Energy, said the Tailem Bend 3 BESS project underscores the company’s commitment to expanding grid-supporting storage across South Australia.
“The Tailem Bend 3 BESS represents a significant milestone in Vena Energy’s growth strategy and a major expansion of our energy storage capabilities,” he said.
“This 408 MWh system adds substantial storage capacity that will support South Australia’s world-leading renewable energy adoption, while aligning with our commitment to developing utility-scale renewable energy and storage assets that contribute to Australia’s clean energy transition.”
The BESS will deliver economic benefits to the region through construction jobs, supplier contracts and flow-on opportunities for local contractors and businesses.
Vena Energy will also prioritise local employment and training pathways for residents and First Nations communities.
