Public Safety Power Shutoff (PSPS)
What Is A PSPS?
A Public Safety Power Shutoff is an operational practice CPI may use to shut off power in high-risk fire areas to reduce fire risks during extreme and potentially dangerous weather conditions.
When Will A Public Safety Power Shutoff Occur?
Many factors can influence whether a PSPS is necessary: the National Weather Service’s Red Flag Warnings–sustained high winds and low humidity, public safety concerns, and “boots on the ground” live reports.
How Will CPI Communicate To Members Before And After A PSPS Event?
Whenever possible, CPI will attempt to notify members approximately 72 to 48 hours in advance of a potential PSPS event and again approximately 24 hours before deenergizing the lines. CPI also intends to provide additional notifications throughout the outage, when power has been shut off and when it has been restored. However, situations may prevent CPI from providing notice as the actual onset of extreme weather conditions and other circumstances beyond CPI’s control may disrupt coordination and notification efforts.
CPI may notify members using automated calls, the CPI webpage, and Twitter.

How Long Will It Last?
Power may remain out for as long as extreme and dangerous weather conditions pose a potential fire risk. Depending on the severity of the weather and other factors, power outages could last several hours or multiple days – so it’s important to have an emergency plan in place.
How Long Before My Power Is Restored?
Even after a PSPS ends, CPI crews will need to visually inspect the power lines before restoring power. These inspections can only occur during daylight hours as operations are limited during overnight hours.
Members should prepare to be without power for an extended time during a PSPS.
How To Prepare?
- Update your contact information with CPI.
- Have a personal safety plan in place for every member of your household (including pets).
- Plan for any medical needs like medications that need to be refrigerated or devices that require power.
- Create or restock your emergency supply kit, including food, water, flashlights, a radio, fresh batteries, first aid supplies, and cash.
- Identify backup charging methods for phones and medical equipment.
- Know how to open your garage door manually.
- Ensure any backup generators are ready to operate safely.
- Identify the unique needs of your family and loved ones in the area for your emergency plan.
- Designate an emergency meeting location.
Generator Safety Tips
- Make sure you turn off the main power switch or breaker in your home
- Don’t overload the generator; use it to only power essential appliances or equipment
- Only operate the generator outside, not indoors
- Try not to open your refrigerator during an outage; the food might be safe after four hours
- Should you have a freezer, a freezer full of food should remain viable for up to 48 hours and 24 hours for a half-full freezer
- CPI is not responsible for spoiled food
