The Federal battery STC rebate is vendor-lead and works in a similar way to the solar panel STC rebates.

Your chosen vendor will submit the rebate application on your behalf.
5. Sign up to Synergy's "Synergy Battery Rewards" program
If you are choosing to apply for the WA State Rebate sign up to the Synergy Battery Rewards programme (you can chose not to opt-in to the Synergy program and still be eligible for the Federal Battery STC rebate).
