Power could be out for another 48 hours for some of the nearly 30,000 Los Angeles Department of Water and Power accounts blacked out by record-breaking heat this weekend, officials said Sunday.
And as temperatures again topped 100 degrees in some parts of the San Fernando Valley, the DWP said people who suffer blackouts Sunday may have to wait a day or two for their power to be restored.
Overloaded distribution stations, overheated or overtaxed underground and above-surface lines, and other large equipment failed Friday, when various parts of Los Angeles hit all-time temperature records. It was 117 at Van Nuys Airport and 111 at UCLA that day.
As of 10 a.m. Sunday, nearly 30,000 Los Angeles Department of Water and Power customers were without power, including nearly 5,000 in Koreatown. That is down from the 37,000 accounts blacked out Saturday, a day that also set temperature records just below Friday’s levels.
Each account represents a residence or business, meanign air conditioning could be out for upwards of 50,0000 Angelenos Sunday.
It was 101 degrees at 2 p.m. Sunday at Van Nuys, but temperatures south of Mulholland had dropped as much as 20 degrees from Friday’s extreme heat.
Sunday, circuit trouble remained centered in a swath of L.A. from the Wilshire and Westlake districts into Koreatown and eastern Hollywood, where more than 11,000 accounts were blacked out as of 10 a.m.
The area between the Hollywood (101) Freeway and Griffith Park had about 5,000 accounts offline, and the Leimert Park and southwest part of Los Angeles had nearly 2,000 addresses without power.
In the San Fernando Valley, blackouts were centered in Panorama City and Sherman Oaks.
Outside the Los Angeles city limits, Southern California Edison reported far fewer problems: 3,758 accounts were without power as of 1 p.m. Some 161 customers in Orange County remained without power.
SCE urged its customers to do whatever they could to reduce pressure on the system, such as keeping thermostats at 70 or above, judicious use of air conditioning and use of drapes, curtains and blinds to keep sunlight and heat out of rooms.
Back in Los Angeles, DWP officials said Saturday’s power demand was the second-highest of any weekend day in the city’s history, with peak use exceeding 5,700 megawatts, one day after a July record of 6,256 megawatts was used on Friday, which was the most used for a single day since 2006 when 6,165 megawatts were used.
