San Francisco power outage hits 90,000, business district affected

SAN FRANCISCO, April 21 (Reuters) - A power outage on Friday morning in San Francisco affected around 90,000 people, stalling work in the technology and finance center as a vast swath of the financial district lost electricity.

Paul Doherty, spokesman for utility PG&E, said there had been an incident at a San Francisco substation and a series of outages began affecting the city shortly after 9 a.m. (1200 ET). He was unable to give an estimate of when the problem would be fixed.

The outage affected central and northern parts of the city, according to the city's Department of Emergency Management.

The same year, the Mission San Francisco de Asís, the oldest surviving structure in the city, was built. The Catholic church was made of adobe, brush, and wood, which weren't the best materials considering California's earthquakes. Here it is in an 1863 photograph

In 1835, English entrepreneur William Richardson founded the city’s first homestead outside Mission San Francisco de Asís, near what is today Portsmouth Square (a one-block park in the city's Chinatown neighborhood).

The same year, Richardson and Alcalde Francisco de Haro, a Mexican soldier, laid out an urban plan for a larger town, named Yerba Buena (“Good Herb” in Spanish) after an aromatic plant native to the area. The town began to attract American settlers.

A decade later, Yerba Buena had doubled in population to nearly 1,000 residents, and the town’s name was changed to San Francisco.

Office workers spilled onto city streets in the heart of the business district, milling about as traffic snarled since stoplights were not working.

King Lip, chief investment officer at Baker Avenue Asset Management in San Francisco said his offices had been hit.

"It's pretty big, seems like half the city has no power. It's a big deal. All our systems went down. We were in the middle of a trade, luckily we have cloud-based software so all the trades are saved and we're going to have our people in Texas or New York execute it," he said.
