The so-called Public Safety Power Shutoffs will also be shorter and confined to narrower areas than the outages this fall that affected millions of people in PG&E's vast territory in northern and central California, Johnson said.
"Over the next couple years, you will see a progression of shorter, fewer PSPS. But the climate change and the weather change is dramatic enough that I don't think we will see the end of it for some period of time," Johnson told the Senate Energy and Natural Resources Committee.
The intentional blackouts have cost customers $10 billion, according to Stanford Law School's Michael Wara.
"This problem is going to get worse, not better, as the years pass," said Wara ,speaking at the same Senate committee meeting. "And it's likely to spread beyond California into a broader impact on the western United States."
Johnson apologized for PG&E causing so many wildfires. He said the company will put safety first, installing more power lines underground and prioritize system hardening.
