In 2018, historic wildfires ravaged California. The Camp Fire destroyed the city of Paradise. It also caused an unprecedented 85 deaths and a widespread power outage.

Investigators found that equipment owned by California utility giant Pacific Gas & Electric (PG&E) (faulty equipment along the Caribou-Palermo electric transmission line) likely started the blaze. That line has since been permanently de-energized.

The admission generated a dramatic drop in PG&E’s profits. The company eventually filed for bankruptcy protection, citing $30 billion in liabilities.

Since then, PG&E has been taking an aggressive approach to fire safety in hopes of preventing a similar disaster. Their new plan, the Public Safety Power Shut-Off Program (PSPS), implements rolling blackouts throughout the state of California.

Although California has been using outages to decrease wildfire risk for years, PG&E’s new program has much broader implications than any program in the past.

Here’s what you need to know about the PG&E rotating outages and how they’ll impact you.
