MAJOR NEW BATTERY POWERS UP TO STRENGTHEN AUSTRALIA’S GRID

Melbourne, Victoria - 6 December 2025 - Equis Australia (Equis) and SEC have officially switchedon the $1.1 billion Melbourne Renewable Energy Hub, marking a major milestonein Australia’s energy transition.

Located in Melbourne’swest, it is one of Australia’s largest grid-scale battery energy storagesystems, capable of delivering energy on demand to power 200,000 homes duringthe evening peak period, drawing on 600 megawatts of capacity and 1.6 gigawatthours of storage.

Equis ManagingDirector David Russell said the project was central to Victoria’s renewableenergy future.

“Melbourne RenewableEnergy Hub is our first project to go live in Australia and the Equis team havedelivered a world-leading project on schedule and on budget,” said Mr Russell.

“Our engineersdesigned a world-first underground 500kV cable connecting a BESS into existinggas-insulated grid infrastructure, our investment team secured a landmark $400mdebt package and it has been impressive to watch the project take shape fromNotice to Proceed in December 2023, installation of 444 Tesla megapacks andthree Toshiba 500kV HV transformers.

“Today’s milestoneshows that when industry and government work together, we can deliver complex,large-scale infrastructure that strengthens the grid, creates jobs, and helpsreduce power prices for consumers.”

Melbourne RenewableEnergy Hub achieved successful registration to the grid for all three batterysystems in parallel., a significant achievement.

SEC CEO Chris Miller said storage is critical forVictoria’s energy transition.

“SEC's $245 million investment was pivotal to theproject's delivery, enabling construction to begin and allowing one of theproject's three big batteries to be upscaled from two to four hours of storage,”he said.

Construction of Melbourne Renewable Energy Hub began in 2024 and finished on schedule, creatingwork and training opportunities for more than 1,200 people, including over 70 traineesand apprentices.

MREH is positioned where Victoria’s criticaltransmission routes join to support the Melbourne metropolitan load and is theonly BESS in Victoria capable of supporting three Victorian Renewable EnergyZones.

Equis Managing Director David Russell said the Melbourne Renewable Energy Hub combinescutting-edge battery technology with Australian engineering expertise, settinga benchmark for speed, quality, and community benefit in energy storagedelivery.
