Please call our faults line on 13 13 51 and we’ll send our crew over to resolve the issue.

To modify your connection (increase your maximum load/ capacity), you can request this at your own cost by submitting an application.

Absolutely, you can upgrade to three phase at your own cost. For pricing information, please contact the customer service centre on 13 10 87.

You’ll need to and pay the full cost of a SPS.

We’ll honour the network connection cost for new connection applications for two years from the date the line was transitioned to SPS, if the network connection is lower than the cost of a SPS. The two-year period commences on the date the property owner is contacted by us, and is tied to the land, not the property owner. If the property is sold during this two year period, the new property owner can apply for a new connection at the lower connection cost. 

To be eligible to receive a new connection at the ‘lowest cost’ during the two-year period,... Read more

No, you’re not required to refuel the SPS generator.

We’re responsible for all SPS maintenance, including refuelling the generator. We service these bi-annually or annually, depending on the size of the SPS. The diesel tank may need to be refuelled more frequently depending on weather and usage.

SPS are fitted with 24-hour remote monitoring dashboards, which provide real time performance. We can see if there is an issue with the SPS or if the diesel tank is running low before the scheduled service date.

If there is an emergency or you experience a fault or outage, you’ll still need to call our fault line on 13 13 51.

One of the benefits of SPS is we don’t need to access your property as often as with traditional infrastructure. We do need to access your property for SPS installation, maintenance and in the case of a hazard or SPS fault.

Where possible, our teams or our SPS contractors, will try to contact you prior to entering your property. If we can’t get in touch, we’ll still need to access the property. As the energy operator, we’re permitted to enter properties for these purposes. For more information, please visit Land Access Legislation.

Your existing solar panels will continue to generate energy in the same way and any excess energy will be fed back to the SPS to charge the battery storage until it reaches full capacity, at which point your solar panels will be isolated.

When the battery storage capacity is reduced to its prescribed (lower) capacity limit, your solar panels will be switched back on and you can continue to utilise your solar panels.

Yes, you can install your own solar panels, however there may be limitations on how you can integrate your panels with SPS.

Please contact us to discuss your options. 

No, you’ll continue to receive a bill from Synergy for the electricity you use. The cost per unit of electricity is the same as network-connected customers, so if your electricity usage stays the same, so will your bill.
