In 2016, six families located in the State’s Great Southern region signed up to receive their energy in a new way, harnessing technology not previously used on our network.
The stand-alone power systems (SPS) trial involved installing units at six farms in the towns of Ravensthorpe, West River, Lake King and Ongerup. The initial 12-month trial used stand-alone power systems that combined solar panels, battery and a back-up generator.
The trial measured the reliability of power supply, our customers’ experience using the new technology , the amount of solar generation and impact on the grid.
The results have been overwhelmingly positive with the customers continuing to receive their energy through SPS.
With more than 200 hours of power outages saved, SPS is transforming power reliability for rural WA.
Meet some of our SPS trial participants, Bernie and Ros and hear what they thought of their SPS.
The 2016 SPS Trial demonstrated that SPS can provide a reliable and safe supply of power to eligible regional customers in WA.
In the first three years, trial participants:

Since the trial started in 2016, the stand-alone power system is now a permanent feature on the participants properties.
One of the trial participants, Ros Giles (pictured), says power outages have reduced significantly and are now considered "very occasional quick hiccups”. Ros and her husband, Berney, are delighted they said yes to the trial - “we’ve forgotten what power outages are."
The success of the trial has led to another 52 SPS units being rolled out as part of Round 1. Given the size and scale of our network the SPS technology is well suited to WA. In fact, it is perfectly suited.
