LOS ANGELES (CNS) - The California Independent System Operator, which manages the state's electric grid, today issued a statewide Flex Alert, calling for voluntary electricity conservation from 2 p.m. to 9 p.m.

"Consumers are urged to conserve electricity especially during the late afternoon when air conditioners typically are at peak use," the California ISO said in a statement. "Consumers can help avoid power interruptions by turning off all unnecessary lights, using major appliances before 2 p.m. and after 9 p.m. and setting air conditioners to 78 degrees or higher."

The ISO noted that the power grid can become strained amid high air-conditioner use in hot weather. It said the peak use expected today is 48,000 megawatts, which would be the highest demand this year.

A Flex Alert is issued when the electrical grid is "under stress," generally from increased power usage due to hot weather.

Cal-ISO officials urged residents to take steps such as:
-- setting thermostats at 78 degrees or higher
-- close drapes and use fans to cool rooms
-- turn off unnecessary lights and appliances
-- delay using major appliances until early in the morning or late in the evening
