Australia's Largest Grid-Scale Battery Project in Victoria Advances Clean Energy Goals

Australia is advancing its clean energy goals with the Mortlake Battery Energy Storage System (BESS) in Victoria. This project, one of the largest grid-scale batteries in the state, will support grid stability and facilitate greater integration of renewable energy. AusNet, Victoria's largest diversified energy networks business, is delivering the transmission connection, with Siemens supplying two state-of-the-art 500 kV transformers.

The Mortlake BESS, once operational, will have a 300 megawatt capacity and a 650 megawatt-hour facility, sufficient to power around 135,000 households. The project requires two highly critical power transformers, designed, manufactured, delivered, and installed by Siemens on a demanding timeline. These transformers will convert stored battery energy into high-voltage electricity, enabling its seamless transmission through the national grid.

The transformers, engineered for cycling and dynamic loading, feature thermally upgraded insulation and advanced cooling technologies. This ensures superior thermal performance, crucial for the project's success. The country's investment in large-scale energy storage, like the Mortlake BESS, is part of its strategy to capture clean energy and deliver it reliably during peak demand. Australia aims to achieve net-zero emissions by 2050, with over 35% of its electricity already generated from renewable sources.

The Mortlake BESS connection is a significant milestone in Australia's clean energy journey. It enables deeper integration of renewables and reinforces grid stability, supporting the country's ambitious climate goals. Siemens' transformers, tailored to meet the project's demanding timeline and performance requirements, play a pivotal role in this landmark project.
