[Australia; 8 December 2025] – Vena Energy, the renewable energy arm of Vena Group and a major green energy solutions provider across the Asia-Pacific region, has commenced construction of a 408 Megawatt-hour (MWh) Battery Energy Storage System (BESS) in Tailem Bend, South Australia, marking a significant expansion of its operations in the region.
Scheduled for commissioning in 2027, the Tailem Bend 3 BESS will become one of the largest battery storage projects in South Australia, supporting the state’s transition to renewable energy and its goal of achieving net zero emissions by 2050.
The BESS will enhance grid stability by storing excess generation and dispatching power during periods of high demand, improving system reliability and contributing to a more resilient and sustainable energy system.
Owen Sela, Head of Australia at Vena Energy, said the 408 MWh Tailem Bend 3 BESS will be Vena Energy’s third energy storage project in Australia, underscoring the Group’s continued expansion of grid-supporting storage across the region.
“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.”
This development marks the third phase of Vena Energy’s broader Tailem Bend energy precinct. It follows the successful 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.
Construction of the Tailem Bend 3 BESS will create new job opportunities, with Vena Energy committed to maximising local employment and training pathways for residents and First Nations communities. The project will also contribute to economic growth in the Tailem Bend region and surrounding areas through procurement of local goods and services.
“We have built strong relationships with the Tailem Bend community through our previous projects over the years, focusing on local partnerships and employment opportunities. Working closely with community stakeholders has been essential to our approach, and we will continue this collaboration as we progress the project,” Owen said.
