Overview

GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Battery/solar incentive program on record

My Energy Optimizer Partner+

SMUD's own battery storage incentive program (separate from the CPUC/IOU-administered SGIP, which does not apply to SMUD customers as a municipal utility outside CPUC jurisdiction). One-time enrollment incentive of up to $10,000 per household ($500/kWh minus a 20% holdback) for new battery energy storage system customers who enroll within 90 days of receiving Permission to Operate (PTO) from SMUD. Ongoing quarterly incentives are currently only available for Tesla batteries ($110 for 1 battery, $220 for 2, $330 for 3+); other eligible brands (Eguana, Enphase, Franklin, SolarEdge, Sonnen) receive only the one-time enrollment incentive at this time.

Status on file: active. Verify current status before relying on this.
