What Caused the San Francisco Power Outage?

PG&E’s initial report points to underground cable failure in the Mission District substation. This is the most common cause of major SF outages:

• Underground cables (60%): SF’s aging underground infrastructure fails under heavy load
• Equipment overload (25%): Winter demand spikes transformers
• Vehicle damage (10%): Construction or accidents hit underground lines
• Weather (5%): Rare in SF but high winds can damage overhead lines

No evidence of cyberattack, fire or weather damage at this time.

When Will Power Be Restored?

PG&E’s current timeline:

Delays possible: 30% of PG&E outages take longer than estimated due to underground repair complexity.

Why Power Outages Happen in San Francisco

SF’s unique challenges:

• Aging underground grid: 70-year-old cables fail under modern loads
• Dense population: 1.5 million people in 47 square miles = massive demand
• Hilly terrain: Equipment works harder in steep neighborhoods
• Winter peaks: Holiday lights + heating = record electricity use

PG&E reports SF averages 12 major outages per year, lasting 2-6 hours each.

How Long Do SF Power Outages Usually Last?

Typical timeline:

• Underground cable (most common): 3-5 hours
• Transformer failure: 1-3 hours
• Overhead line damage: 30 minutes-2 hours
• Major substation: 6-12 hours

85% of outages restored within 4 hours. Current outage on track for normal resolution.

Safety Tips: What To Do During SF Power Outage

Immediate Actions

• Unplug electronics to protect against power surges when electricity returns
• Use flashlights, not candles (fire risk skyrockets in outages)
• Elevators: Don’t use. If stuck, call 911
• Gas appliances: Turn off if smell gas

Stay Safe Overnight

• Keep fridge closed – stays cold 4 hours, freezer 48 hours
• Charge devices now – power banks essential
• Check neighbors – elderly especially vulnerable
• Stay warm – layer up, avoid using gas stoves for heat

Business Owners

• Backup generators auto-start?
• POS systems on battery backup?
• Security cameras recording?
