Compare Synergy's residential plans to find the best fit for your battery system. Calculate real savings based on your usage patterns.
Quick answer
Synergy's two current residential plans price the same electricity very differently: A1 charges a flat 33.26c/kWh, while Midday Saver ranges from 8.85c/kWh between 9am and 3pm to 55.33c/kWh across the 3pm to 9pm peak. This calculator applies each Synergy plan, including the Battery Rewards overlay, to your own usage pattern and shows which one leaves you ahead with a battery.

Based on the current published Synergy residential price schedule
Most Perth metro homes are on Synergy's network. Key residential tariffs include A1 (flat rate) and Midday Saver (time-of-use, with a cheap 9am-3pm super-off-peak window), plus the Battery Rewards (Tier 2) VPP overlay for battery owners.
Household electricity in Perth and the South West is supplied by Synergy, so there are no rival retailer offers to shop between. What moves your bill is the plan you sit on and, for battery owners, whether the Battery Rewards overlay pays its way. That is the comparison this calculator runs.

Battery Rewards (Tier 2) Maximises Your Savings
Under the current WA framework, Tier 2 VPP participation earns 70¢/kWh during activation events plus 10¢/kWh peak DEBS (3-9pm). This unlocks the WA Battery Scheme rebate (up to $1,300, 10kWh max eligible).
Average Perth home: 15-25 kWh/day
Peak: 3pm-9pm weekdays
Super off-peak: 9am-3pm. Shift load here (or charge your battery) to win on Midday Saver. Off-peak (9pm-9am) is the remaining 40%.
