At the San Diego Union-Tribune, "Outages hit countywide; 115K without power":
About 115,000 customers endured a power outage Sunday afternoon after a failed generator put stress on a power grid that was already under heavy demand on a sizzling summer day.
Communities from Mission Valley to San Clemente were left without power when the outages first struck about 1:20 p.m. About an hour later, nearly 44,500 customers, mostly in North County, were still affected. Power was restored by 3 p.m.
The outages knocked out traffic signals, causing traffic jams, and businesses left suddenly without the power were turning customers away.
San Diego Gas & Electric initiated the outages after a generator in the region went off line about 11:50 a.m. causing transmission lines to overload. The California Independent System Operator, the state's main grid operator, had SDG&E drop 150 megawatts of load in order to avoid overloading other lines, said Anne Gonzales, a spokeswoman for the state operator. One megawatt powers approximately 650 homes.
Only SDG&E customers were affected...
