Victorian households are set to benefit from a substantial strengthening of the state’s energy grid, with the State Electricity Commission (SEC) confirming a significant $43 million investment in the new Baranduda Electrical Energy Reserve. Announced on September 16, 2026, this strategic move secures a minority stake and a 15-year power purchase agreement for 50% of the output from the massive 400-megawatt (MW) / 1.86-gigawatt-hour (GWh) battery energy storage system (BESS).
The Baranduda battery, slated to commence construction in November 2026 and become operational by late 2028, is positioned to play a critical role in stabilising Victoria’s energy supply, particularly as older coal-fired power stations approach retirement. Located strategically near Wodonga, adjacent to the Wodonga Terminal Station and the vital Victoria–NSW electricity interconnector, the project aims to store abundant renewable energy and dispatch it during peak demand periods, effectively powering over 200,000 Victorian homes through the evening.
SEC’s Strategic Investment and Grid Resilience
The SEC’s $43 million commitment marks a significant step in the Victorian Government’s re-establishment of public ownership in the energy sector. This investment, alongside partners Aware Super and Birdwood, represents the first public-private partnership between the Carroll Labor government and a superannuation fund to deliver a renewable energy project in Victoria. The long-term power purchase agreement ensures that a substantial portion of the battery’s output will directly support Victorian Government and commercial customers, with the remainder available to the broader electricity market.
“This big battery will be able to power more than 200,000 Victorian homes through the evening peak while creating around 150 jobs during construction,” said Minister for Energy and Resources Jaclyn Symes.
The Baranduda Electrical Energy Reserve is designed with a 4.65-hour duration, positioning it, at least for now, as the longest-duration battery storage system in Victoria. This extended capacity is crucial for providing sustained power during periods when renewable generation, such as solar, is unavailable, and demand remains high. The project will consist of four independent 100 MW units, enhancing its operational flexibility and reliability.
Economic and Environmental Benefits for Victorians
Beyond bolstering grid stability, the Baranduda BESS is expected to deliver tangible economic and environmental benefits. The construction phase alone is projected to create approximately 150 jobs, with further ongoing roles once the facility is operational. For consumers, the ability to store cheaper renewable energy and release it during high-demand times is anticipated to help alleviate upward pressure on electricity prices, contributing to lower energy costs for households and businesses across the state.

The deployment of large-scale battery storage like Baranduda is fundamental to Victoria’s ambitious renewable energy targets. By integrating more intermittent renewable sources into the grid, these batteries reduce reliance on fossil fuel generation, thereby cutting carbon emissions. They also enhance grid resilience, offering a robust safeguard against potential power outages and supporting the overall reliability of the electricity network.

The Role of Large-Scale Batteries in Australia’s Energy Future
The Baranduda project is part of a broader national trend towards significant investment in large-scale battery storage. These systems are crucial for managing the influx of rooftop solar and other renewable energy sources, preventing curtailment, and ensuring a stable, reliable power supply. They also facilitate the growth of Virtual Power Plants (VPPs), which aggregate distributed energy resources to provide grid services, offering further opportunities for consumers to participate and save.
