SEC’s giant battery now powering Victoria
06 December 2025
SEC has marked a significant milestone today with its giant 600-megawatt battery project in Plumpton now powering Victorian homes and businesses, storing energy and feeding it back into the grid in time for the start of summer.
The Melbourne Renewable Energy Hub is one of the biggest batteries in the world, capable of supplying electricity to up to 200,000 homes during Victoria’s evening peak demand period.
Co-owned by SEC and Equis Australia, the Hub has a storage capacity of 1.6 gigawatt hours and will help accelerate the State’s energy transition. Strategically positioned at the confluence of several of Victoria's critical transmission routes, the Hub will strengthen our electricity network and unlock capacity for more renewable energy.
SEC CEO Chris Miller said the Melbourne Renewable Energy Hub was SEC’s first investment and is designed to add significant storage capability to our transitioning power system.
“The Hub will soak up excess wind and solar power during the daytime and shift that energy to the evening peaks when we need it most,” Mr Miller said.
“SEC's $245 million investment was pivotal to the project's delivery, enabling construction to begin and allowing one of the project's three big batteries to be upscaled from two to four hours of storage. I commend our partner, Equis Australia, together with all suppliers, contractors and delivery partners who worked tirelessly to deliver the Hub to market – on time and on budget.”
The Hub has created work and training opportunities for more than 1,200 people. Around 20% of the total working hours on the project were performed by over 70 trainees and apprentices.
The project prioritised local businesses, with more than a dozen Melbourne-based companies providing services and supplies such as electrical works, civil construction, traffic management, landscaping and construction materials.
Equis Managing Director David Russell said: “Today’s milestone shows that when industry and government work together, we can deliver complex, large-scale infrastructure that strengthens the grid, creates jobs, and helps reduce power prices for consumers.”
The Melbourne Renewable Energy Hub was the first investment from SEC's initial $1 billion towards building 4.5 gigawatts of new renewable energy and storage projects – helping to accelerate the energy transition and bring down the cost of energy for Victorians.
