Western Australia’s Horizon Power Embarks on DERMS Project To Manage PV & Batteries

Last week, PXiSE Energy Solutions, LLC a subsidiary of Sempra Energy and Mitsui & Co. Ltd., announced that Horizon Power would be installing the company’s Active Control Technology (ACT) as the distributed energy resources management system (DERMS) in Western Australia.

PXiSE’s DERMS will provide Horizon Power with continuous, high-resolution visibility into the operations of the solar panels, batteries and generators in its approximately 888,000-square-mile service area. The platform will automatically respond to conditions on the grid by discharging power stored in batteries to correct any real-time disturbances and ensure a smooth, two-way flow of electricity across its systems.

The financial terms of the agreement were not disclosed.

“With increasing customer demand for behind the meter energy resources, we will need innovative technology to enable us to efficiently manage the resources while maintaining our highest safety and reliability standards,” said Terry Mohn, general manager of Advanced Microgrid Developments for Horizon Power.

The deployment of PXiSE DERMS solution will enable Horizon Power to manage and orchestrate various DERs and further transition to a higher percentage of renewable resources.

The PXiSE Active Control Technology platform runs on a standard Microsoft Windows platform and uses an imbedded OSIsoft software and synchro-phasor data to enhance, analyze and respond to grid data from numerous power resources.

The continuous higher-resolution visibility and artificial intelligence balances a mix of renewable energy, storage and traditional generation on the electrical grid, according to the company.

The PXiSE software application currently controls DERs at renewables projects, including Auwahi Wind in Hawaii and in microgrids at Sempra Energy’s headquarters in San Diego and a winery in Sonoma County, California.


OSIsoft is exhibiting at the upcoming DistribuTECH, which takes place in New Orleans, LA from February 4-6, 2019. DER Management and Control is just one of the many topics that will be discussed during the event.
