How the heck does San Francisco lose power?!
All that high tech stuff needs power, right? So you'd think they'd make sure they had it, right? CBS Local:
SAN FRANCISCO (CBS SF) — Heavy wind and rain from Thursday’s massive storm have left much of San Francisco without power for most of the day, with 276,000 PG&E customers system wide losing power since the storm started, and 110,000 still without power.
San Francisco was hardest hit, with 70,000 customers across a vast swath of the city including downtown high rises in the dark beginning early Thursday morning through mid-morning. ...
The outage forced the shutdown of the Bay Area Rapid Transit Montgomery Station for a time Thursday morning. A transformer blew out near high-rise hotels, including one out front of the Grand Hyatt Hotel. The Embarcadero Center was also shut down for a time after power went out there as well..
[PG&E spokesman Joe Molica] said they have been preparing for the storm for more than a week, but weren’t anticipating as many trees and wires coming down. “All summer we’ve been hearing from our vegetation department that a lot of trees have been stressed, so they were very susceptible to coming down,” he said. “That’s exactly what we saw today. A lot of wires coming down. We do want folks to be safe out there. If you see a downed or hanging low wire, please call us and stay away.”
I love the idea of a "Vegetation Department."
Speculating freely, if the trees were stressed, I wonder if that was because of the drought? If so, the outage is an example of an unexpected restult from a complex system.
NOTE Here's a blow-by-blow from Wolf Richter. Our systems are much more fragile than we think, aren't they? ZOMG no Internets!
