(CBS13) — PG&E estimates around 800,000 customers will lose power starting overnight on Tuesday, including approximately 50,000 customers in both Placer and El Dorado Counties, and 43,000 in Nevada County.

It could take several days to restore power in some areas. Here’s what you need to know about the planned outages:

Sacramento and Roseville, however, should not be affected by the outages, because they are not serviced by PG&E. Learn more here. 

Also, some cities were listed as a mistake on Tuesday. Learn more here.

HOW LONG WILL THE SHUTOFFS LAST?

That depends. Crews are expected to begin shutting off the power in some areas early Wednesday, just after midnight. PG&E said power will be turned off in stages, depending on the local timing of the severe wind conditions.

Based on the forecasted weather event, the utility expects peak winds to last at least through midday Thursday.

After they determine the severe weather event has ended, crews must then inspect equipment for damage before restoration. This process can take several days depending on the damage.

Make sure to update your information with PG&E, so you can get the latest alerts for your area.

WILL SCHOOLS BE OPEN?

Several school districts have canceled school due to the PG&E Public Safety Power Shutoffs planned for Wednesday.

Here is the current list of closures. The list will be updated as more districts announce closures.

ARE THERE COMMUNITY RESOURCE CENTERS?

If you are affected by the blackouts, you can go to a Community Resource Center in your county where PG&E will provide restrooms, bottled water, electronic-device charging and air-conditioned seating. The centers will open at 8 a.m. Wednesday and will be open during daylight hours only.

WILL PG&E COMPENSATE CUSTOMERS WHO HAVE POWER SHUT OFF DUE TO FIRE RISK?

According to the website, PG&E operates a “Safety Net Program” and will reimburse customers who are without power for more than 48 hours due to a severe event, including weather. The shut off scheduled for Wednesday would not fall under this category; however, customers will not get charged for power since they are not consuming any power.

A PG&E spokesperson told CBS13, “PG&E does not reimburse customers for losses, as power will be shut off for safety when gusty winds and dry conditions, combined with a heightened fire risk threaten a portion of the electric system.”

IS MY FOOD OKAY?

The USDA says food will stay safe in a fridge for up to four hours during a power outage. After that, many perishables are no longer safe to eat. Click here for a guide on what to keep and what to toss from your fridge.
