The first big roll out of stand-alone power systems.

An innovative energy alternative for regional customers 

SPS Round 1 follows the success of the 2016 Trial where we installed stand-alone power systems at six properties in the Great Southern region. We are now extending our deployment of SPS to better understand how the systems can be used at scale in a range of locations across our grid. Participants can expect greater reliability and power quality of supply, with the long-term aim of removing the aging poles and wires from their property entirely.

Fifty-two sites were identified that meet the required eligibility criteria. These locations are serviced by more than 230km of overhead distribution powerlines - that’s four kilometres of powerline per property, all of which needs to be replaced at a significant cost in the coming year.

Participants also come from a more varied energy consumption background, allowing us to deploy a more diverse set of SPS configurations and sizes.

Reliable and renewable power for rural customers

Did you know, one SPS unit can power an entire farming property, making them a game-changer for rural customers.

Combining solar panels with a battery and back-up generator, the SPS units provide locally generated power.

The numbers
As part of Round 1, 52 units will be rolled out which will deliver better power reliability for rural and isolated customers. But that's just the start - more SPS locations have been identified over the next 30 years...

Freezers, food and the farm

It takes less than 24 hours for a freezer half full of food to defrost.

So if your property sits at the end of a long spur line, where power outages can occur fairly frequently, you can often come home to an unpleasant smelling fridge or freezer. That was the case for Three Springs farmer, Ian McKenna.

So when we approached Ian about installing a stand-alone power system (SPS) on his property, he was delighted.

“I knew about the Ravensthorpe trial and thought it sounded great, so I’d been hoping it would come here".

What did the locals have to say?

“There’s 42km of poles and wires running to that transformer and we’re hoping they will be able to get rid of them as they won’t be needed. We’d be really pleased about that as they are a bushfire risk and a bit of a pain when you are trying to crop around poles...”

"Buying a generator would have cost us around $10,000, so the timing for getting SPS was good as it saves us on that cost, as well as giving us more reliable power.”
Kelvin & Lara Kent
“As well as giving us better power supply, it would reduce our bushfire risk as the poles and wires in the area won’t need to be used.”
Barry Heydenrych

“I knew about the Ravensthorpe trial and thought it sounded great, so I’d been hoping it would come here. That unit will be enough for the house, given I’ve even got a wood-fired hot water system.”
Ian McKenna
Three Springs
“As well as not having to tidy up around the poles, we don’t need to touch the SPS units. Western Power even come out to check and fill up the back-up generator for us, so we don’t need to touch anything.”

WA - the perfect place for SPS

With thousands of kilometres of long power lines across WA, SPS is a game changer for energy supply in regional WA.


With solar panels, a battery and diesel generator back-up, SPS lets rural properties generate their own renewable and reliable energy. It is a safer, more reliable and more economical alternative to replacing poles and wires in many remote and isolated areas.

Our SPS projects have transformed energy supply for our rural customers.
