Technology group Wärtsilä will deliver the fourth stage of the Eraring battery facility at Origin Energy’s Eraring Power Station in New South Wales.
The expansion adds 360MWh of new energy storage capacity to the project, bringing the total capacity of the Eraring battery to 700MW/3,160MWh.

This will make it the largest battery project in Australia and one of the largest in the world. The extension will also allow the Eraring battery to provide increased capacity to help balance the grid as renewable generation grows and coal-fired plants retire.
The Eraring battery connects to Australia’s National Electricity Market (NEM) and provides critical grid services, including frequency control, firming capacity, and system strength support, that enhance system security and reliability as variable renewable energy supply increases.
Stage 4 will utilise Wärtsilä’s fully integrated, modular, and compact Quantum energy storage system. The project is supported by a multi-term service agreement, ensuring long-term reliability and optimal system efficiency.
Wärtsilä president energy storage and EVP Tamara de Gruyter said, “This extension marks another important milestone in Wärtsilä’s path towards enabling a secure, renewable energy future in Australia and around the world.
“Alongside Origin, we are setting a new global benchmark for large-scale energy storage with one of the largest and most advanced battery energy storage facilities in the world.”

Origin selected Wärtsilä for Stage 1 of the project in 2023, and for Stages 2 and 3 in 2024.
The Stage 4 extension will commence in December 2025 and is expected to be completed by early 2027.
