Update: How Bay Area cities, counties, transit agencies are preparing for power outage

PG&E has confirmed a massive Public Safety Power Shutoff that could begin as early as midnight Wednesday and last up to five days in portions of 34 counties across Northern and Central California, affecting up to 800,000 customers.

The planned outage is a response to anticipated wind gusts that the National Weather Service said could reach up to 70 mph in some areas Thursday. The high winds and dry conditions present excessive fire danger and power is being shut off to avoid sparks in the case that power lines are knocked down.

PG&E’s PSPS alert website has been down much of Tuesday, overwhelmed by people attempting to check the shifting outage map and looking for updates. However, people can register for alerts in their area by texting “ENROLL” to 97633.

City, county and transit officials throughout the North, East and South Bay are quickly working to prepare for the shutoff. Specific area information can be found below and will be updated as the situation progresses.  

PG&E PG&E is planning to shut off power to approximately 800,000 customers beginning Wednesday, October 9, 2019 in Northern and Central California due to fire danger associated with gusty winds and dry weather. The Planned Safety Power Shutoff could last for up to five days. This outage map was provided before the PG&E website went down Tuesday due to excessive traffic. Additional areas have been added to the scheduled shutoff since.

All schools in the San Leandro Unified School District will be closed Wednesday.

Santa Rita County Jail should not impacted because the facility’s power is self-sufficient.

Portions of northeast Concord are now within the scheduled shutoff area. Up to 1,600 Walnut Creek customers could be impacted and the city offers alerts for those who register using the WC Alert system.

Caltrans officials said the Caldecott Tunnels between Alameda and Contra Costa counties may close Tuesday evening. Power is required to operate tunnels and the transportation agency is working with PG&E to try and establish emergency power, but that is not a guarantee at this point.

South Bay:

BART officials say they do not anticipate service disruptions during the power outage. They claim their ability to “pull power from other sections” of the power supply system will keep trains moving and generators will be used to maintain tunnel fans and other critical systems.

SMART trains are expected to run regularly.

Motorists are urged to use or listen to newscasts for the latest information. Both sets of tunnels may be closed for as many as five days.
