(CNN) California's largest utility company is warning about 850,000 customers that another intentional power outage may leave them in the dark this weekend.

Pacific Gas & Electric (PG&E) has been cutting off electricity for customers in northern and central California over the past weeks in an attempt to avoid sparking wildfires. But this could be the utility's largest outage this year.

Estimates indicate the potential outage could affect more than 2 million people, a spokesperson with the company said.

Customers across 36 counties in Northern and Central California may lose power through the weekend due to a round of gusty winds in the state, the utility announced Friday.

Some of the areas that may be impacted are Humboldt, the Sierra foothills, Western Sacramento Valley and the greater Bay Area. Paradise, which was devastated by last year's deadly Camp Fire , could also be impacted by the blackout.
