Benefits of stand-alone power systems include:
Reliability and power quality improvements – significantly less power interruptions for customers currently located on long spur lines in regional areas.
Better value – more cost efficient than replacing and maintaining long feeder lines.
Modular – each unit can be augmented to adapt to a customer’s changing energy requirements.
Lowers bushfire risks in regional areas.
Reduction in land access – asset footprint in most cases will be reduced from tens of kilometres to approximately a ten-metre squared installation.

Stand-alone power systems (SPS) offers a reliable, cost-effective alternative in rural areas to vast lengths of powerlines that currently connect only small groups of customers. In selected regional locations, SPS technology is a more efficient option when compared to current and forecast network costs.
The success of our first stand-alone power system (SPS) trial has resulted in strong interest by regional families and businesses who would love to have their own system.
At this point only those properties identified by Western Power as part of SPS Round 1 can participate in the project.
We have identified the potential participants based on where single or small clusters of customers are located on long, ageing spur lines which are due for replacement; and their annual energy consumption patterns.
There is no additional cost for selected customers to participate in a stand-alone power system (SPS) round. We cover all costs associated with SPS including site investigations, system installation and ongoing maintenance.
Participants will continue to receive a bill from Synergy for the electricity they use. The cost per unit of electricity continues to be the same as network-connected customers, so if electricity use stays the same, so will the customer’s bill.
The main source of stand-alone power system (SPS) generation is renewable energy, such as solar panels. This power is used immediately by the customer and excess power is stored in the battery. The battery has significant capacity to cover a customer’s needs at night and during periods where generation is low (such as several cloudy days in a row). The system is sized to match the power use of the property to ensure it is fit for purpose.
The job of the inverter is to convert the Direct Current (DC) power to Alternating Current (AC) power appropriate for home and business use. The back-up... Read more
A stand-alone power system or ‘SPS’ is an energy supply unit made up of a renewable energy source or sources, a battery, inverter and, in most cases, back-up generation. The unit operates independently of the main electricity grid to store and deliver reliable power to a household or business. It remains part of Western Power’s service area, with our business owning the unit and being responsible for the installation and ongoing maintenance.
