San Francisco Power Outage: Miscommunication Inflates Customer Impact

A recent power outage in San Francisco caused significant confusion when PG&E's notification system inaccurately reported that 120,000 customers were affected. The actual number was closer to 9,400. The incident also disrupted Waymo's robotaxi services due to traffic signal failures. As restoration efforts continue, PG&E has committed to investigating the cause of the outage and ensuring public safety remains a priority. This situation has drawn increased scrutiny towards PG&E's operations as a government-sanctioned monopoly in the region.

Overview of the Power Outage

On Saturday morning, San Francisco experienced a power outage that was exacerbated by a communication error. At approximately 9:45 a.m., a standard procedure at two substations triggered a protective device, leading to the blackout. PG&E reported that the Richmond and Golden Gate Park neighborhoods were the first to lose power. Shortly after, their notification system erroneously indicated that around 120,000 customers were affected, a figure that was significantly inflated.

Clarification from PG&E

PG&E spokesperson Edgar Hopida clarified the situation, emphasizing that the 120,000 figure was incorrect. The outage involved two distinct electrical circuits, and the notification system mistakenly categorized the incident under a larger protective device, leading to the exaggerated count. The actual number of customers impacted was corrected to about 9,400 within half an hour.

Impact on Robotaxi Services

The outage also disrupted services beyond residential areas. Waymo, Alphabet's autonomous taxi service, temporarily halted its operations in San Francisco due to the power failure affecting traffic signals across the city.

Increased Scrutiny on PG&E

This miscommunication drew heightened scrutiny towards PG&E, a government-sanctioned monopoly in Northern California. Despite being overseen by state regulators, the company faces no competition in its service areas, which raises concerns about accountability.

Areas Most Affected

According to outage maps, the Richmond District experienced the highest concentration of outages, with between 500 and 4,999 residents losing power. Smaller outages, affecting 50 to 499 customers, were reported near San Jose Avenue, while other areas saw outages impacting fewer than 50 customers.

Restoration Efforts

By noon, around 2,500 customers remained without power as repair teams worked diligently. System operators began rerouting some customers to alternative circuits to expedite restoration efforts. Initially, PG&E estimated that power would be restored by 12:30 p.m., but this was later revised to 2:30 p.m. The company has committed to investigating the cause of the outage and reaffirmed its dedication to public safety.
