A new era in regional power supplies
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.

3 in a row: Great Southern trial proves SPS great for country WA
With more than 200 hours of power outages saved, SPS is transforming power reliability for rural WA.

Stand-alone power brings opportunities for WA companies
Meet some of our SPS trial participants, Bernie and Ros and hear what they thought of their SPS.
Results of the trial
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:
- avoided more than 200 hours of power outages
- avoided an average 71 hours of outages a year
- had more than 90 per cent of their power generated from the SPS solar panels
- satisfaction with their power supply increased from 6/10 pre-trial to more than 9/10 with SPS in place.

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.
And on to Round 1
The success of the 2016 trial has led to the roll-out of more SPS across WA. This is part of Round 1, where 52 SPS units will be installed and commissioned in regional WA. These 52 locations have been selected for SPS as they are situated on long regionally located powerlines that are due for significant renewal.
Many of the customers recruited for Round 1 have different drivers for opting in to the project, such as existing poor reliability and power quality that should be significantly improved by the SPS; reduced land access requirements and the potential to removal the existing overhead assets from their properties.
