Perth company wins switchyard works for Collie battery

Collie battery

As announced by the Western Australian Government here.

Synergy has awarded the switchyard works, worth about $50 million, to Perth-based company SCEE Electrical as part of the Collie battery energy storage system project.

The award is a variation to a balance of plant contract and is for SCEE Electrical to deliver a 330kV switchyard, substation, and supporting ancillary buildings and equipment for the project.

The switchyard will connect the Collie battery to Western Power’s network to support renewable energy integration and grid stability.

The project works include the supply, installation and commissioning of 330kV transformers, circuit breakers, surge arrestors, current/voltage transformers and a control room.

On 2 May 2024, Synergy announced SCEE Electrical was awarded a $160 million contract for the balance of plant works at the Collie battery. This includes installing and commissioning about 640 battery container units and 160 inverters.

The 500 megawatt/2000 megawatt hour Collie battery is due to be completed late in 2025. It will be one of the biggest battery energy storage systems in Australia.

Battery energy storage systems collect excess energy from rooftop solar and wind farms during the day and release it when needed in the evening and at peak times.

With State-owned coal-fired power stations due to be retired by 2030, the WA Government has committed $2.3 billion for Synergy to deliver new battery storage.
