California's Independent System Operator declared a Stage 2 emergency Sunday, warning residents to prepare for blackouts and advising them to conserve energy. However, it lifted the Stage 2 Emergency just after 9 p.m. The flex alert will continue on Monday from 3 p.m. through 9 p.m.
Stage 2 means, "The ISO has taken all mitigating action and is no longer able to provide its expected energy requirements," CAISO said.
The California ISO took the same action on Saturday.
Power remains out for 70,000 Los Angeles Department of Water & Power customers as recently as 9 p.m., while it's been restored to 77,000, the department says. Due to the high number of outages, full power restoration is not expected for another 24 to 48 hours, according to the department.

"Consumers should prepare for outages," CAISO said in a tweet. "Conservation will be critical to avoiding or limiting power interruptions."
Thousands of residents in Southern California remained without power Sunday, as a record-breaking heat wave blanketed the region and fires burned across the state. Gov. Gavin Newsom urged conserving energy to avoid blackouts Sunday afternoon.
About 47,500 Southern California Edison customers were without power Sunday evening, according to Reggie Kumar of SCE.
