Who to call to start service at a new address in Mountain View.
Power comes from PG&E
PG&E (Pacific Gas & Electric Co.), an investor-owned utility, serves all of Mountain View. 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 Contra Costa Water District
Contra Costa Water District supplies Mountain View: about 50% of residents live in its service area. About 50% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws surface water (EPA lists the East Bay Municipal Utility District (EBMUD) and Randall-Bold Water Treatment Plant as sellers) and serves 198,000 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 86% of the 332 systems serving 100,001–250,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2026–Dec 2028, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 3.2 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
