Power conservation alert issued for California

PG&E initially said that more than 5,100 customers in Concord were without power.

Issued Monday by the state's power grid manager, the Flex Alert asks California residents to voluntarily conserve electricity from 2 p.m.to 9 p.m. Tuesday and Wednesday.

"At 100 degrees, for every degree over that, can mean we have to generate hundreds of megawatts more in order to meet that one degree increase", says Greenlee.

The alerts, which call for voluntary power conservation, are issued by the California Independent System Operator or ISO, which oversees the state's electrical grid.

"It's been really rough with a 2-month-old and 2-year-old and trying to keep them from getting heat rash", said Tarver.

In response to the heat wave, several Los Angeles cooling centers - including recreation centers and senior centers - will have extended hours today and Wednesday.

The elderly and young children are advised to stay out of the heat and make sure they're hydrated, Palo Alto Deputy Fire Chief Catherine Capriles said.

The current heatwave, which is expected to last through Thursday and possibly longer, may not seem that dramatic in San Francisco, where temperatures are just above normal and things are still pleasant. When you are home, set your thermostat to 78-degrees or higher and turn it off when you head out the door.
