Who to call to start service at a new address in Rutherford.
Power comes from PG&E
PG&E (Pacific Gas & Electric Co.), an investor-owned utility, serves all of Rutherford. Its homes paid an average of 37.5¢ per kWh in 2025, about $174 a month (its average across California, for customers on its standard service).

Water comes from City of Napa water system
The City of Napa water system supplies almost all of Rutherford. It draws surface water (EPA lists City of Calistoga and City of St. Helena and City of American Canyon and Town of Yountville as sellers) and serves 84,804 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 90% of the 597 systems serving 50,001–100,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2022–Dec 2024, was 0.0 ppb, below the 15 ppb action level that applied. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
The system’s full record: EPA ECHO report
EPA SDWIS via Envirofacts (violations pulled Oct 9, 2026) and ECHO (lead samples, 2026Q3); service area: EPA Community Water System Service Area Boundaries v3.0. Violations are counted by the start of their compliance period. CA2810003.
