PG&E says Contra Costa outage was about 1,300 customers, not 20,000

PG&E said Friday’s Contra Costa County outage was far smaller than its public outage map first suggested, correcting a count that briefly showed more than 20,000 customers without power.

The utility later said about 1,300 customers were actually affected and that service was restored in less than 10 minutes. PG&E spokesperson Tamar Sarkissian said the larger figure appeared after the company’s Distribution Management System misread the signal on an associated device.

The outage and the correction came on a day when Bay Area customers were already watching a run of PG&E disruptions. Two earlier outages in San Francisco on June 24 and June 25 affected thousands of customers and added to scrutiny of the utility’s reporting and restoration process.

What PG&E said

According to PG&E, the Friday afternoon incident in Contra Costa County was brief and limited. The utility said the public outage map overstated the number of affected customers because of the signal-reading error, not because tens of thousands of people actually lost power.

PG&E said the exact cause of the smaller outage affecting roughly 1,300 customers was not immediately clear. The company did not provide additional repair details in the initial correction.

Why it matters

The correction materially changes the public understanding of the incident. What initially appeared to be a major East Bay blackout was, in PG&E’s account, a short outage affecting a much smaller number of customers.

The episode also raises questions about the reliability of outage maps that customers and local officials use for real-time situational awareness during service disruptions.

What to watch next

PG&E has not yet explained what caused the underlying outage or whether it will issue a more detailed follow-up on the misread device signal. Further clarification could come if the utility releases additional incident information or if local officials seek a public explanation.

The Friday correction also follows a week of Bay Area outage activity, which may keep attention on how PG&E reports and updates service interruptions in real time.
