LOS ANGELES (AP) — California’s power grid operator has called for a second day of voluntary energy conservation as the state swelters under a record-setting heat wave. The California Independent System Operator has issued a Flex Alert for 6 to 9 p.m. Friday. The alert was already in place for 5 to 10 p.m. Thursday. People are urged to set thermostats to 78 degrees or higher and avoid using major appliances. The governor has signed an emergency declaration that would free up additional power if needed. Palm Springs tied an all-time high temperature of 123 degrees.
