PG&E map of power shutdown areas in San Mateo County

In preparation for a potential PG&E Public Safety Power Shutoff (PSPS) anticipated to begin Thursday, Oct. 24, the County of San Mateo is encouraging residents to sign up for up-to-date alerts through PG&E and SMC Alert.

The County is one of 15 counties alerted by PG&E that portions may have power proactively turned off due to high winds and fire danger. Currently, PG&E is in “watch” status and anticipates deciding at 10 a.m. Wednesday, Oct. 23 if a PSPS will occur. Per PG&E, if a PSPS does happen in San Mateo County, the timeline is as follows:

·     1 a.m., Thursday, Oct. 24: PSPS begins

·     Noon, Thursday, Oct. 24: Re-energization begins

As of Tuesday afternoon, PG&E estimates the potential PSPS would impact 907 customers total, including 15 medical baseline customers, in the areas of Woodside, La Honda and unincorporated San Mateo County in that area.

PG&E has assured the County that due to the smaller number of affected customers, re-energization should not take a long period of time.

The San Mateo County Office of Emergency Services is closely monitoring the situation and working closely with the potentially impacted areas, our public safety partners and agencies like CHP and Caltrans. Our goal now, as always, is ensuring our communities are informed, prepared and safe. 

Please reserve 9-1-1 for emergencies only. 

For potential facility or road closures in specific impacted jurisdictions, please visit those city or town websites.

·     Identify backup charging methods for phones and keep hard copies of emergency numbers.
