Residential Impact

• Lighting & heating: 39,000 homes reported loss of electric heating, prompting a spike in demand for portable heaters.
• Communication outages: Many residents lost broadband access,as major ISPs (Xfinity,Sonic) rely on the same feeder.
• Food safety: The San Francisco Department of Public Health advised residents to discard perishable foods left above 40 °F for more than 2 hours.

Rapid checklist for affected households

1. Check circuit breakers – Reset any tripped breakers before contacting PG&E.
2. Preserve food safety – Move unopened refrigerated items to a cooler with ice packs.
3. Use battery‑powered devices wisely – Prioritize phones for emergency calls.
4. Report hazards – Notify the city if you spot downed power lines or gas leaks.

BART Service Disruptions

• Stations closed: Embarcadero, Montgomery, Civic Center, and 12th St. Oakland City Center (served by the Transbay Tube).
• Alternative transport:
• Muni Bus routes 30, 38, 45 were deployed as “shuttle buses” between affected stations.
• Ride‑share partners offered 15 % discount codes through the BART app.
• Ridership impact: An estimated 85 % drop in peak‑hour boardings between 00:00-06:00 PT.

PG&E Response & Restoration Strategy

• Deployments: 6 line crews, 2 substation specialists, and a mobile transformer unit.
• Tools used:
• Infrared thermography to locate hot spots on the feeder.
• Remote‑controlled switches for rapid isolation of damaged sections.
• Restoration phases:

1. Stabilization – secure the faulted line and reroute power through alternate paths.
2. Re‑energization – Gradually re‑close breakers while monitoring voltage stability.
3. Testing & verification – Conduct load‑balance tests on critical infrastructure (hospitals, data centers).
