Understand your Synergy bill in Mandurah
Mandurah is on the Synergy (SWIS) network, so the same WA tariffs and feed-in rules apply to every home here. BillWise reads your bill and shows you exactly what you're paying for.
What bills look like in Mandurah
Mandurah skews older, with a large share of retirees who are home through the day. Being home in daylight changes the maths: more of your usage can be covered by solar you generate rather than power you buy. Mandurah is also one of the country's biggest rooftop-solar postcodes, so feed-in credits matter here too. BillWise factors both into your bill.
What drives a Synergy bill
Every Synergy bill in Mandurah is built from the same few levers. Knowing which one is costing you most is the whole point of a bill analysis.
The Synergy Home Plan (A1) charges 33.26c per kWh for the power you use, flat across the day. The more you draw from the grid, the more this line grows.
A fixed 119.24c a day lands on every bill before you use a single unit. On a low-usage home, this quietly becomes the biggest share of the total.
If you export solar, Synergy's solar export payment scheme (DEBS: Synergy's payment for the solar power you send back to the grid.) pays 10c per kWh at peak (3pm to 9pm) and 2c at other times, on the first 50 units exported each day. Using your own solar is worth more than exporting it.
Households that add a battery on the Synergy network can also claim the WA Residential Battery Scheme rebate, worth up to $1,300. BillWise flags the rebates you may be eligible for as part of your bill breakdown.
