The operator of the state’s electric grid is urging the public to cut power consumption on Tuesday and Wednesday to help California get through what’s expected to be a record-breaking heat wave. The Flex Alerts are the first issued this year by the California Independent System Operator Corp. (CAISO) and will remain in effect from 5 p.m. to 9 p.m. both days. “This heat wave could be like a long one we had in 2006, when lots of records were set and there were power problems,” said Alex Tardy, a forecaster at the National Weather Service in Rancho Bernardo.
