Flex Alert issued for California for Wednesday from 4 p.m. to 9 p.m.

FRESNO, Calif. -- The California Independent System Operator (ISO), the operator of the state's power grid, has issued a Flex Alert for Wednesday as a heat wave settles into the area.

All Californians are asked to reduce their use of energy between 4 p.m. and 9 p.m. to reduce strain on the power grid.

The ISO issued the alert, saying supplies of energy across the West were tight.



People are urged to turn off unnecessary lights, delay using major appliances until after 9 p.m., and set air conditioner thermostats to 78 degrees or higher, if health permits.
