Press Release – Leading the renewable energy transformation in Western Australia

Media Release

Leading the renewable energy transformation in Western Australia

  • Horizon Power has successfully commissioned a solar farm and utility scale battery in the Pilbara coastal town of Onslow.
  • PXiSE Microgrid Controller is successfully managing the output of the solar farm and utility scale battery in coordination with the power station in Onslow.

Horizon Power, Western Australia’s regional and remote energy utility, is leading the renewable energy transformation with a demonstration project that enables the integration of much higher levels of renewable energy into an isolated microgrid in the remote town of Onslow.

With a goal to provide more sustainable and cleaner electricity to its customers, and decrease generation costs, Horizon Power’s Onslow project integrates the solar farm and battery storage system with a gas-fired power station, coordinated by the PXiSE Energy Solutions Microgrid Controller.

For the Onslow project, the PXiSE Microgrid Controller uses high-speed data from connected energy assets to simultaneously optimize renewable energy output and power quality. Lower operating costs are expected, as solar power displaces diesel generation.

Onslow customers have also been incentivized to install solar and battery at their homes as part of the project which tests the management of renewable energy in an isolated regional community.

Horizon Power Chief Executive Officer Stephanie Unwin said the work underway in Onslow was a significant part of the State’s renewable energy transformation, building both Western Australian capability and more renewable-friendly systems for their regional communities.

“The microgrid management technology is an amazing piece of technology that is new to this State and allows for the careful management of the various energy sources in the town,” she said.

“The entire PXiSE team applauds the dedication of Horizon Power to bring more renewable energy to the communities they serve by completing this milestone” said Patrick Lee, PXiSE Chief Executive Officer.

“We look forward to the next stages of the project where, ultimately, the full management system will offer Horizon Power a more granular and comprehensive level of insight into their network.” – Andrew Todd, Chief Executive Officer, GTSgroup, a PXiSE project partner.

“By controlling and coordinating energy storage and generation assets, Horizon Power will be empowered to directly engage its customers as participants in the transition to a more renewable grid and away from costly fuel imports,” said Mr. Lee.
