Australia, Victoria: The State Electricity Commission’s (SEC) Melbourne Renewable Energy Hub (MREH) has reached a major milestone, with the third and final transformer for its 600 MW battery energy storage system now delivered to site.
Following the arrival of the first two units in January 2025, this marks a key step toward the project’s completion and expected launch in late 2025. The transformers are essential components, enabling efficient two-way energy flow between the BESS and the transmission grid while minimizing energy loss over long distances.
Once fully connected, the system will be able to store and discharge up to 1.6 GWh of electricity, enough to power 200,000 Victorian homes during peak times.
The MREH comprises three major battery components:
- A1 and A2 (200 MW / 400 MWh each) made up of 110 battery units apiece
- A3 (200 MW / 800 MWh) comprised of 224 units
Together, they form one of Australia’s largest battery projects, co-owned by SEC and Equis Australia. The site is designed with advanced inverter technology to support voltage and frequency on the grid, replacing lost system inertia as coal-fired stations retire.
With approval for expansion up to 2.4 GWh, the Melbourne Renewable Energy Hub is poised to play a central role in strengthening Victoria’s clean energy future.
