Powering Off for Wildfire Safety
A Public Safety Power Shutoff (PSPS) is when an electric utility temporarily shuts off power to reduce the risk of a fire caused by utility equipment. Dangerous fire weather conditions — which include strong winds, dry vegetation and low humidity — drive PSPS events.
Losing power for any amount of time is a hardship; while it’s frustrating and inconvenient, safety must come first. Our mission is to keep the power on when it is safe to do so.
PSPS Frequently Asked Questions
PSPS FAQ
Alerts are available for anyone. Before a potential PSPS, we’ll send notifications via email, text or phone message. Sign up or update your contact information for PSPS alerts in English or other available languages.
4-7 Days Ahead
When forecasts indicate extreme fire conditions, we begin predictive modeling to assess potential impact. Our weather awareness map shows counties of concern for PSPS up to seven days ahead.
4 Days Ahead
We continue to refine predictive models. Incident responders are placed on alert.
3 Days Ahead Notification
When extreme fire conditions are forecast, we coordinate with the emergency management community, first responders and local government.
We notify potentially affected customers and show affected areas on the Outage Map. PSPS areas are indicated with lines showing the potentially affected circuits. Not all PSPS events can be forecasted this far in advance.
2 Days Ahead Notification
As the forecast becomes more precise, we update the list of circuits that might be impacted. If weather conditions persist, impacted customers and public safety partners receive a notification confirming the PSPS event and timing.
1 Day Ahead Notification
When extreme fire conditions are imminent, we continue to coordinate with the emergency management community, first responders, local government and customers of possible PSPS.
1-4 Hours Before Shutoff Notification
If we estimate that power could be shut off within one to four hours, an expected shutoff notification will be sent to customers, when possible. Once customers receive this notification, power shutoffs could happen at any time until the end of the PSPS event.
Power Shutoff Notification
When wind speeds and fire conditions are about to reach or exceed predetermined thresholds, we notify the emergency management community, first responders, local government and customers when we shut off power.
Before Power Restoration Notification
When fire conditions subside and PSPS is no longer needed, field crews will check lines to make sure power can be safely restored. Customers are notified when line inspections begin. It typically takes up to eight hours for inspections to be completed for all deenergized lines or it might take more time if daylight is required by foot or helicopter patrols.
Restoration Notification
All customers notified about PSPS will receive a final notification when their power has been restored or when the event has ended.
Other notifications may occur as needed to keep customers informed.
Disclaimer: Our advance forecasts might not capture the real time onset of strong winds or other dangerous fire conditions. In these cases, there might be little to no notice before power is shut off for PSPS. After a shutoff, customers will be notified as soon as possible and can check the Outage Map to confirm it is due to PSPS.
During dangerous fire weather conditions, when strong winds, dry vegetation and low humidity are forecast, we start considering PSPS. Under these conditions, a fire could spread rapidly, posing a significant safety risk. PSPS reduces the risk of winds causing branches or other debris to come into contact with utility equipment and start a fire.
PSPS decisions are based on real-time weather reports from pole-top weather stations on or adjacent to PSPS circuits. We primarily consider these factors and conditions when deenergizing a circuit or circuit segment:
- Strong winds
- Low humidity
- Dry vegetation that could serve as fuel
Use our weather and fire monitoring tools to stay informed.
- Stay informed about developing weather with our seven-day outlook.

Customers who live in high fire risk areas are more likely to experience PSPS. However, customers who live near high fire risk areas may also be affected because they are connected to power lines that run through or near high fire risk areas.
To check if you are in high fire risk area, enter your address on our Outage Map and select the “high fire risk area” filter.
While some customers may not be experiencing high winds at their home or business, they may be served by a circuit which starts in or crosses a windy high fire risk area before reaching their address. As a result, one block or neighborhood may have power while others don’t. We do our best to reduce outage impacts by temporarily switching neighborhoods to nearby circuits, but this is not always possible. Additionally, since all circuits must be visually inspected by crews on the ground before restoration, not all circuits will be restored at the same time.
Resources and Preparedness Frequently Asked Questions
Resources and Preparedness FAQ
Sometimes PSPS lasts over 24 hours. Have an emergency plan to keep your family safe during any outage. That includes a list of the location of emergency items such as water bottles, a battery-operated radio, flashlights, first aid kits, extra blankets and working batteries.

If you or someone in your house relies on electricity for health reasons, you may be eligible for our Medical Baseline Allowance program.
SCE supports customers during PSPS and other large public safety events through Community Resource Centers and Community Crew Vehicles. During PSPS, visit the Outage Map for locations. Locations are usually posted up to a day before a projected PSPS outage.
Services include information, light snacks and resiliency kits. Customers may charge their mobile devices and portable medical equipment. We also offer in-language support and accommodate customers with disabilities or other access and functional needs.
To be better prepared for PSPS and other emergency outages, we offer incentives through the Self-Generation Incentive Program (SGIP). These systems work as backup batteries to power your home when an outage or PSPS occurs.
Customers in high fire risk areas or other qualifying communities may be eligible for resiliency incentives through SGIP. Customers who do not live in a high fire risk area or other qualifying communities can still apply for SGIP general market incentives.
For more information, visit the SGIP Battery Storage for Residential Customers Fact Sheet.
Visit the SCE Marketplace for portable power stations and generators. Portable power stations provide backup power for small devices and household appliances such as laptops, mobile phones, tablets and some internet routers. Portable generators provide backup power for larger household appliances and devices such as refrigerators, lighting, water pumps and garage doors.
