Standalone Power Systems

The more remote the location, the more critical it is to have a safe, reliable source of power.


We're installing 50 Standalone Power Systems (SPS), customised to meet the needs of our end-of-grid customers.

These SPS will operate independently from the main electricity network and provide renewable energy via solar panels, battery storage, an inverter and a backup generator. 

The project is being delivered as part of Horizon Power’s $75 million Renew the Regions program, a WA Recovery Plan initiative aimed at creating jobs and improving services in the regions.

Empowering our regional communities

This off-grid solution will support our customers who live and work in remote locations. We take into account the energy usage of each property before customising a system to suit its occupant’s needs.

Not only are these systems cleaner and greener, they’re safer too. With no poles and wires to maintain, they reduce the risk of bushfires and minimise farming hazards.

The roll-out of these units will provide better power reliability, quality and safety to some of our more isolated, end-of-grid customers, and help us create a greener WA.

How does it work?

Solar panels, battery storage, an inverter and a backup generator all work together at different times of the day to deliver reliable clean power to your property.

  • Solar panels are the main source of power and generate electricity when the sun is out.
  • Batteries provide power at night and when the sun isn’t shining for long periods of time.
  • The low noise back up generator will kick in on occasions when more power is needed than what the solar panels and batteries can provide. 


Did you know?

In 2022, we partnered with Telstra to transition Western Australia’s first remote mobile tower from an overhead power supply to a standalone power system (SPS).

The SPS is providing next generation solar and battery technology to generate and store electricity without the need for the tower to be connected to the overhead electricity network, and is being trialled by Telstra in its ongoing efforts to strengthen network resiliency.

Bushfires, floods and cyclones can have a devastating impact on our network infrastructure and off-grid power solutions like this can help keep our communities safe, connected and informed during stressful events.

What does this mean for our community?

Horizon Power is committed to putting the regions first

This project is especially rewarding because it is delivering locally manufactured, fit-for-purpose, renewable energy solutions to some of our most isolated customers, and it’s boosting local jobs and supporting regional businesses along the way.
