**PG&E Outage Tests Waymo’s Autonomous Fleet During San Francisco Blackout**
Key Takeaways:
- A PG&E power outage disabled nearly one-third of San Francisco on Saturday
- Dark traffic signals disrupted both human and autonomous traffic, challenging Waymo’s AV service
- Waymo is updating its fleet and safety protocols based on lessons from the outage
San Francisco, CA — A major “pge outage” in San Francisco over the weekend disrupted electricity across wide swaths of the city and posed a critical test for Waymo’s autonomous vehicle fleet. The outage, which hit on Saturday, led to over 7,000 traffic light failures and created substantial gridlock, forcing both city officials and AV companies to adjust operations in real-time.
Waymo’s AV System Strains Under Emergency Conditions
The outage, attributed to regional utility provider PG&E, left approximately one-third of San Francisco without power. The blackout shut down thousands of traffic signals, turning busy intersections into unmanaged four-way stops. Waymo reports that its fleet of robotaxis successfully navigated over 7,000 dark signals on Saturday, but the surge of traffic and safety confirmation requests initiated a backlog in its system — compounding gridlock across already-stressed streets.
In response, Waymo suspended operations, instructing its vehicles to safely pull over and eventually return to depots in stages. The company emphasized that these steps were implemented to avoid interfering with emergency responders and prevent further congestion during the outage peak.
Lessons Learned and Technology Updates
Waymo, a subsidiary of Alphabet Inc., has now announced several key improvements to its AV systems based on this incident. Originally designed with ultra-cautious protocols during signal outages, the company’s vehicles would often request human operator confirmations at dark intersections — a safeguard that proved cumbersome during a city-wide blackout. The company is now updating its fleet with the ability to ingest real-time outage data, allowing the autonomous driver to make more independent and timely decisions during power failures.
Waymo is also expanding its first responder training, having already trained more than 25,000 emergency professionals worldwide. Coordination with Mayor Lurie’s administration continues as Waymo enhances its emergency preparedness for future urban disruptions.
Long-Term Impact for Urban AV Operations
This outage serves as a case study for how AV platforms can — and must — adapt to infrastructure failures. As cities across the U.S. invest in autonomous transit and smart traffic systems, the ability of AVs to operate effectively in non-ideal conditions is essential. Waymo’s 100+ million miles of autonomous driving have prepared it for many situations, but large-scale blackouts present unique challenges. Future upgrades will determine how successfully the company can integrate outages into its decision-making algorithms, establishing new standards for autonomous resilience.
