San Francisco authorities are urging residents to stay indoors after a power outage affected 130,000 customers due to a fire at a power plant, causing traffic lights to stop working.

Local authorities in San Francisco, USA, declared a state of emergency Saturday night, urgently urging residents to stay indoors and only leave for essential reasons. This warning followed a sudden and widespread power outage that paralyzed traffic and rendered traffic lights inoperable across large parts of the city.

In a video posted on the X platform (formerly Twitter), local official Daniel Lowry emphasized the seriousness of the situation, noting that the power outage coincided with heavy rain and darkness. In his message to residents, Lowry said, "It's raining, and it's late at night, so we urge anyone who doesn't have an urgent need to go out to stay home for their safety.".

Details of the outage and containment efforts

Pacific Gas & Electric (PG&E), the region's main power provider, reported that the outage affected approximately 130,000 customers in the city. The company stated that it was working closely with rapid response teams and local officials to restore power. Officials later confirmed that the primary cause of the widespread outage was a fire at a power substation, which led to its shutdown.

To counter the traffic chaos caused by the traffic lights being out of order, traffic police officers were deployed in large numbers at major intersections and vital streets to regulate traffic and prevent accidents, especially in light of the rainy weather conditions that increase the risks of driving.

The context of California's energy crises

This incident has once again highlighted the challenges facing California's energy infrastructure. The state frequently experiences problems with the stability of its electrical grid, whether due to extreme weather, wildfires, or the aging of some power plants. Pacific Gas and Electric (PG&E) is constantly under scrutiny regarding the readiness of its grid and its ability to handle emergencies, as the region has witnessed similar incidents in previous years that affected millions of residents.

Expected impacts and the importance of response

A power outage in a city the size and importance of San Francisco, a global center of technology and the economy, has repercussions that extend far beyond simply cutting off lights to homes. Disruptions to public transportation and traffic signals directly threaten public safety, and prolonged outages can disrupt business operations and essential services. Experts emphasize that the swift response of local authorities and the dissemination of early warnings, as demonstrated in this instance, play a crucial role in minimizing losses and preventing accidents until power is fully restored.
