LOS ANGELES — Faced with a record-setting heat wave sweltering California and fueling two major fires, officials extended a flex alert calling for voluntary energy conservation through Friday, hoping to prevent rolling blackouts.
During a flex alert, consumers are urged to reduce their electricity use from 4 to 9 p.m., when the grid is most stressed because of high demand and less available energy from solar panels.
Flex alerts were also issued Wednesday and Thursday. The heat wave is expected to extend well into next week.
