Flex alert goes into effect Tuesday as heat wave lingers
The alert will be in effect Tuesday between 11 a.m. and 6 p.m. During that time, customers are asked to keep thermostats at 78 degrees or higher, to turn off air conditioning when not at home, to turn off unnecessary lights and appliances, and to restrict the use of major appliances to the morning and late evening.
The Independent System Operator issued a similar alert last week and officials said customers had heeded the call, reducing energy consumption by nearly 1,000 megawatts.
That amounts to about half the power lost due to a continuing outage at the San Onofre nuclear plant, which has been out of service for more than six months because of severe equipment problems. The plant supplies enough power for 1.4 million homes when running at full capacity.
Temperatures were expected to cool slightly in Southern California on Tuesday — where triple-digit temperatures have scorched valley areas for more than a week — but were still expected to surpass the 100-degree mark. The National Weather Service said downtown Los Angeles would see a high near 90 degrees.
