There’s plenty of reasons why utilities across Australia are turning to stand-alone power systems (SAPS) as an alternative to traditional poles and wires on their networks. Particularly when it comes to replacing aging infrastructure.

SAPS incorporates the latest in solar and battery technology to generate off-grid renewable energy, and is proving in some instances to be a more viable, lower cost-to-service power solution for utilities.

For Condingup farmers Graham and Gina Darlow they no longer need to make sure their generator is hooked up ahead of a storm coming in.

“The SAPS made it possible for more than 100 power poles and wires to be removed from our paddocks.”

“Without power we can’t get water to the house,” Gina Darlow said.

“Since it was common for the power to go out in a storm, we would always need to make sure the generator was hooked up and ready to go whenever there was a storm warning.”

Improved power reliability is just one of the benefits the Darlow’s have enjoyed since transitioning to SAPS in late 2019 as part of an infrastructure upgrade by their utility, Horizon Power.

“Not only has the removal of the poles and wires made it easier and safer to operate machinery in the paddocks, but it has also addressed the issue we had with the cattle scratching themselves against the wooden power poles.

“When it’s a 1,000 kilogram bull having a scratch, it’s only a matter of time before the poles will start to destabilise.”

The destabilisation of the power poles coupled with the cow’s repetitive scratching would cause the poles to sway and power lines to knock together. Previously, this presented a serious risk of pole top fires igniting in the Darlow’s paddocks.

Two SAPS totalling 21.6 kilowatts of solar capacity now power the Darlow’s home and farming operations. While a smaller 0.9 kilowatt Nano SAPS powers several hundreds of kilometres of electric fence.

The Darlow’s said since having the SAPS installed, they have experienced just one power outage.

“That’s a significant improvement from how it used to be,” Gina said.

“On average, we would experience an outage of some type at least once a week. Sometimes it was just a short drop out, but other times the power could be out for hours while they tried to locate the problem and fix it.

“Not anymore – power outages are a thing of the past. I honestly don’t even think about the power anymore. It’s just always on.”
