Our most ambitious project to date is the Battery Energy Storage System (BESS) for the NSW Government’s Waratah Super Battery Project, developed and operated by Akaysha Energy.

CPP is responsible for the installation of the BESS, as well as the design and construction of the associated balance of plant works, including grid connections—delivering a comprehensive, end-to-end contribution to this landmark initiative. The Waratah Super Battery Project’s BESS is the world’s most powerful battery—a transformative energy solution designed to bolster grid stability and energy reliability for New South Wales.

At the heart of the project is the System Integrity Protection Scheme (SIPS) Control System, operated by Transgrid, which uses advanced detection technology to monitor network contingencies and faults.

CPP’s role has been instrumental in realising the technical backbone of the project, overseeing the design and construction of vital infrastructure. This includes not only the 850 MW BESS, but also a new 330 kV substation and an overhead line connecting to the Munmorah Substation.

Additional milestones include the construction of 12 ring main unit (RMU) buildings, three switchgear buildings, and a dedicated control building—each a testament to the project’s scale and complexity.

CPP scope of works:

• Design and engineering
• Procurement
• Manufacturing
• Construction
• Commissioning
