See what Synergy's Battery Rewards Virtual Power Plant (VPP) could pay you each year.
General information, not financial advice. Rebates and tariffs change.
Quick answer
Synergy's Battery Rewards VPP pays 70c/kWh your battery discharges during activation events, which run up to 30 times a year across the evening peak. This calculator estimates your annual credits from battery size and discharge share, on top of normal DEBS export earnings. Joining is also what qualifies Synergy customers for the WA Battery Scheme rebate of $130/kWh, up to $1,300.

This information is general in nature and does not constitute financial, tax, or legal advice. Rebate amounts, eligibility, and tariff rates change frequently and may not be current.
Consult a licensed financial advisor, tax professional, and electricity retailer to understand your specific situation. We are not responsible for financial decisions made based on this information.
On peak-demand evenings (typically 3-9pm), Synergy discharges your battery remotely to help steady the grid. You are credited 70¢ per kWh it sends out, on top of the DEBS export credits you already earn.
Important: Under the current WA framework, Battery Rewards (Tier 2) participation is required to access the WA Battery Scheme rebate ($130/kWh up to $1,300 for Synergy customers, 10kWh max eligible). Learn more about the May 2026 framework.

You earn these whether or not you join the VPP, so they are not in the totals above. It is a blended estimate at the 10¢/kWh peak and 2¢/kWh off-peak rates for a typical daily export, and does not change with the sliders.
How an event works: during an activation event (typically 3-9pm), Synergy discharges your battery remotely to help steady the grid. You are credited 70¢ per kWh it sends out. Separately, as a DEBS customer you also earn export credits whether or not you join.
Note: real earnings vary with how often events are called, how full your battery is at the time, and how much power your household is using. These estimates are deliberately conservative. Battery Rewards participation is required for WA Battery Scheme rebates under the current framework.
