How to read this guide
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.

Utility and generation supplier
Utility
Pacific Gas & Electric (PG&E)
Willits is confirmed to be within PG&E's electric service territory — independently checked rather than assumed, since neighboring Ukiah (also Mendocino County) operates its own municipal electric utility.
Sources & confidence
Generation supplier
Sonoma Clean Power (SCP) (Community Choice Aggregator)
Willits, a Mendocino County city, is therefore served by SCP. PG&E continues to deliver the power and provide billing/customer service. Some supporting official material could not be independently confirmed from the full source in GridPermit's latest review. Verify the current requirement with the authority before relying on it.
