Contracts awarded for Australia’s largest SPS rollout


From July 2021, 98 stand-alone power systems (SPS) will be rolled out across WA’s network marking Australia’s largest single rollout of SPS.

The units will provide a more reliable, greener power supply to residents across the South West Interconnected System including: Kalbarri, Three Springs, Merredin, Jerramungup and Rocky Gully.

The successful WA contractors are: Hybrid Systems, BayWa r.e. Solar Systems, Balance Utility Solutions and AGL Energy Services – who are working with Bunbury subcontractor Positive Off-Grid Solutions.

SPS are a more efficient option than traditional poles and wires in supplying electricity to regional households and businesses. The units typically include solar panels, a battery and, where required, a back-up generator.

The 98 units will replace around 330km of overhead powerlines, which would have needed to be replaced at a significant cost. They will also improve land amenity for farmers and reduce bushfire risk.

“Through the McGowan Government’s Energy Transformation Strategy, we’re revolutionising the way we deliver and provide energy to Western Australian homes,” Johnson said.

“Stand-alone power systems are an excellent alternative for regional customers and while they’re part of Western Power’s service area, they operate independently to the main grid.

“The increased rollout of SPS is creating new jobs and training opportunities for Western Australians.

“These new contracts will create jobs for Western Australians and support small businesses during the manufacture, installation and commissioning phases.”
