The plan by PG&E Corp. comes after the bankrupt utility said a transmission line that snapped in windy weather probably started last year’s Camp Fire, the deadliest in state history. While the plan may end one problem, it creates another as Californians seek ways to deal with what some fear could be days and days of blackouts.

Some residents are turning to other power sources, a boon for home battery systems marketed by Sunrun Inc., Tesla Inc. and Vivint Solar Inc. But the numbers of those systems in use are relatively small when compared with PG&E’s 5.4 million customers. Meanwhile, Governor Gavin Newsom said he’s budgeting $75 million to help communities deal with the threat.

“I’m worried,” Newsom said Thursday during a budget briefing in Sacramento. “We’re all worried about it for the elderly. We’re worried about it because we could see people’s power shut off not for a day or two but potentially a week.”
