Perth-based company SCEE Electrical has been awarded a $50 million contract to construct the switchyard works for Synergy’s Collie battery project.
This contract is in addition to the $160 million worth of civil, electrical, and major equipment installation works that SCEE Electrical is already undertaking for the project.
The new scope of work includes the construction of a 330-kilovolt switchyard, substation, and support ancillary buildings and equipment to connect the Collie battery to Western Power’s network.
This development marks a significant step forward in the construction of one of the world’s largest battery energy storage systems.
The Collie battery, with a capacity of 500 megawatts and 2000 megawatt-hours, is scheduled for completion in late 2025.
It will play a crucial role in Western Australia’s transition to renewable energy by collecting excess energy from rooftop solar and wind farms during the day and releasing it during peak demand periods.
This project is part of the WA government’s $2.3 billion commitment to Synergy for the development of new battery storage systems.
These systems are designed to support renewable energy integration and maintain grid stability as the state plans to retire its coal-fired power stations by 2030.
Acting Energy Minister Dr Tony Buti expressed his satisfaction with the project’s progress, stating: “The Cook government is committed to building one of the biggest battery systems in the world, and it’s great news that a Perth-based company is playing a leading role in bringing this project to fruition.”
Collie MLA Jodie Hanns emphasised the project’s significance for the local community: “Collie will continue to play a vital role in the energy system for decades to come, having powered WA for over a century.”
The Collie battery project represents a major step in Western Australia’s sustainable energy future, promising to deliver better energy outcomes for households and businesses while supporting local jobs and the economy.
