SMUD Battery Rebate Calculator
Estimate SMUD’s home battery enrollment incentive, Tesla VPP income, and the price boundary for your battery quote.
Enter the battery size and total quote. We’ll show the modeled net cost, program value, payback range and the uncertainty that can move them.
What this SMUD battery estimate is designed to answer
This SMUD battery rebate calculator separates the enrollment incentive from ongoing VPP income. It uses the battery size and installed quote to estimate net cost, then adds a range for energy value and the selected program participation assumptions before calculating a payback range and maximum quote boundary.
Inputs used
- Battery nameplate capacity in kWh and total installed quote.
- Number of batteries, because the modeled Tesla VPP payment varies by household battery count.
- Whether PTO was within the last 90 days, which controls the modeled enrollment incentive.
- Solar and Storage Rate participation and Tesla battery selection for the current VPP income model.
How to read the result
The result helps separate the value of an upfront enrollment incentive from recurring program income. It should be read as a decision range, since actual dispatch, rate-plan savings, battery performance, eligibility, and future VPP terms can change the outcome.
How SMUD battery rebates and VPP income affect payback
SMUD’s home battery storage program can combine an enrollment incentive with ongoing virtual power plant income. The timing of PTO, battery eligibility, number of batteries, Tesla participation, and the Solar and Storage Rate all affect which parts of the value can be included in a quote decision.
- The current model uses nameplate capacity at $500/kWh less a 20% holdback, capped at $10,000 per household, for the enrollment incentive.
- Tesla VPP income is modeled at $110, $220, or $330 per quarter depending on the selected battery count; non-Tesla VPP income is currently modeled as zero.
- The enrollment incentive is excluded when PTO is marked as more than 90 days ago, and program rules should be confirmed with SMUD before purchase.
SMUD battery calculator FAQ
Can I use this calculator for a non-Tesla battery?
Yes. You can estimate the enrollment incentive and energy value, but the current first version models ongoing quarterly VPP income as zero for non-Tesla batteries. Check SMUD’s current eligible-model and participation terms for the system you are considering.
Why does PTO timing matter for the SMUD rebate estimate?
The current model includes the enrollment incentive only when PTO was within the selected 90-day window. The actual deadline and documentation requirements should be verified against SMUD’s current program instructions.
Does the result include the value of backup power?
The first-pass result does not assign a guaranteed dollar value to outage protection. Backup value depends on your priorities, outage exposure, load profile, system configuration, and the price you are willing to pay for resilience.
