The Complete California PSPS Guide: Power Shutoff Alerts, Safety and Preparation

You may receive a power outage notification from your utility company, even when no wildfire is visible and no storm-related damage has occurred in your area. 

For many California residents, this situation is increasingly familiar.
A California Public Safety Power Shutoff (PSPS) is a planned electricity outage intended to reduce wildfire ignition risks during dangerous weather conditions.

Strong winds, dry vegetation, and low humidity can create conditions where damaged electrical equipment could start a rapidly spreading wildfire.

But why do utilities shut off power before anything happens? How long can these outages last, and what should families prepare?

This guide explains California PSPS, how to check alerts, what to expect during an outage, and how to prepare for electricity disruptions safely.

What Is a Public Safety Power Shutoff (PSPS)?

A Public Safety Power Shutoff, commonly called PSPS, happens when an electricity utility temporarily disconnects power to certain locations to reduce the risk of electrical infrastructure igniting a wildfire.

According to the California Public Utilities Commission (CPUC), utilities may take this precaution when dangerous fire weather presents a significant risk.

Unlike an unexpected blackout caused by equipment failure, a PSPS is a deliberate safety measure.

California electricity providers operating PSPS programs include:

• Pacific Gas and Electric (PG&E).
  
• Southern California Edison (SCE).
  
• San Diego Gas & Electric (SDG&E).

Different utility companies may follow their own wildfire safety guidelines, which can include cutting electricity temporarily when fire danger is elevated. 

A PSPS does not automatically mean a wildfire has started or that residents must evacuate.

However, it signals conditions serious enough to require additional preparedness.

Why Do California Utilities Shut Off Power During Fire Weather?

Electrical equipment can become a potential ignition source when strong winds and dry conditions occur together.

Wind may damage power lines, cause tree branches to strike electrical equipment, or blow vegetation into energized infrastructure.

If electrical faults create sparks near dry grass or brush, a wildfire could begin.

To reduce that possibility, utilities may temporarily turn off electricity in areas considered vulnerable.

The decision generally considers:

• Forecast wind speeds and gusts.
  
• Relative humidity.
  
• Dry vegetation and surrounding fuel conditions.
  
• Location and condition of electrical infrastructure.
  
• Local fire weather warnings and observations.

The goal of a planned power shutoff in California is to prevent a possible equipment-related wildfire, not respond to an existing household electrical problem.

Which Weather Conditions Can Lead to a California Public Safety Power Shutoff (PSPS)? 

A combination of strong winds, low humidity, and dry vegetation may increase the likelihood of a PSPS.

California's Santa Ana and Diablo wind patterns can create particularly dangerous conditions in certain regions.

A Red Flag Warning from the National Weather Service may contribute to a utility's assessment.

However, a Red Flag Warning does not automatically trigger a PSPS.

Power companies consider equipment safety, nearby plants, local terrain, and current weather conditions when determining whether a temporary power outage is necessary. 

For a detailed explanation, read our guide to Red Flag Warnings vs. Fire Weather Watches.

Which California Areas Are Most Likely to Experience PSPS?

Communities near forests, grasslands, canyons, and other wildfire-prone landscapes may face higher exposure.

PG&E determines areas at elevated wildfire risk by referring to California’s official fire hazard classifications. 

Southern California Edison and San Diego Gas & Electric identify high-risk areas where powerful winds and at-risk power infrastructure could contribute to wildfires. 

However, properties outside high-fire-threat zones can sometimes be affected because an electrical circuit may serve multiple communities.

Whether your address is included depends on the utility's system configuration and conditions during the event.

Check your electricity provider's official outage map for address-specific information.

How Will You Know If a PSPS Is Planned in Your Area?

Utilities use several notification methods to inform customers about possible PSPS power outages.

Depending on the provider, these may include text messages, phone calls, emails, mobile application alerts, and website updates.

Advance notices may begin around 48 hours before a potential outage, with additional updates as conditions develop.

However, forecasts can change rapidly. Utilities cannot guarantee that every household will receive a specific amount of advance warning.

Where to Check California PSPS Alerts

Use your electricity provider's official website:

• PG&E Public Safety Power Shutoffs
  
• Southern California Edison
  
• San Diego Gas & Electric PSPS Updates

Make sure your account details are up to date and sign up for any available emergency notifications. 

Check local emergency notifications separately because utility outage notices and wildfire evacuation alerts serve different purposes.

How Long Can a Public Safety Power Shutoff Remain in Effect? 

There is no fixed duration for a California PSPS power outage.

Some shutoffs may last several hours, while others continue longer if dangerous weather persists or electrical equipment requires inspection.

Why Doesn't Power Return Immediately After Winds Stop?

Before restoring electricity, utilities may need to inspect affected power lines, poles, and other equipment for damage.

Crews must confirm that reenergizing the system will not create additional hazards.

Damaged infrastructure may require repairs before power can return.

As a result, PSPS power restoration can take additional time after weather conditions improve.

Always rely on the latest utility restoration estimate rather than assuming electricity will return immediately after the wind decreases.

How to Prepare for a Public Safety Power Shutoff

The best PSPS preparedness plan begins before an outage notification arrives.

Start by identifying which everyday necessities require electricity.

Consider lighting, refrigeration, phones, internet equipment, electric garage doors, medical devices, and household cooling or heating.

Prepare the following essentials:

• Drinking water and nonperishable food.
  
• Prescription medications and first-aid supplies.
  
• Battery-powered or rechargeable lights.
  
• Phone charging cables and backup batteries.
  
• Emergency radio and local contact information.
  
• Important documents and emergency cash.
  
• A family communication and evacuation plan.

Learn how to operate electric gates and garage doors manually.

If your household depends on electric water pumps, prepare for possible water-service interruptions.

Keep your vehicle charged or fueled and review local wildfire evacuation routes.

What Should You Do During a PSPS Power Outage?

Once electricity is shut off, prioritize household safety and communication.

Use flashlights or rechargeable lighting rather than candles to reduce fire hazards.

Limit unnecessary phone use to conserve battery power.

Limit how often you open the refrigerator and freezer to help preserve the cold temperature during a power outage. 

According to CDC food safety guidance, an unopened refrigerator generally keeps food safely cold for approximately four hours.

A full unopened freezer can maintain safe temperatures for about 48 hours, while a half-full freezer generally lasts around 24 hours.

These are general estimates; actual food temperatures determine safety.

Avoid using outdoor grills, charcoal burners, or camping stoves inside your home.

Never approach fallen power lines. Treat all damaged electrical infrastructure as energized, even when neighborhood electricity is off.

Continue monitoring utility updates and local emergency instructions.

What If Someone Depends on Electricity for Medical Equipment?

A PSPS outage for medical equipment users requires more detailed advance planning.

People relying on oxygen concentrators, powered wheelchairs, ventilators, refrigeration-dependent medications, or other essential devices should establish a backup plan with their healthcare provider.

Ask the utility about its Medical Baseline program and available support for customers with access and functional needs.

Depending on eligibility and provider, assistance may include additional notifications, preparedness resources, or battery-support programs.

However, enrollment does not guarantee uninterrupted electricity.

Do not rely on an ordinary phone power bank to operate medical equipment unless compatibility and safe operation are specifically confirmed.

Arrange alternative power or a safe relocation plan before an outage creates a medical emergency.

What Are Community Resource Centers During a PSPS?

Some California utilities open Community Resource Centers (CRCs) during Public Safety Power Shutoffs.

These locations may provide device charging, drinking water, outage information, and other assistance.

Southern California Edison also operates Community Crew Vehicles during certain events.

SDG&E shares guidance on accessing Community Resource Centers as part of its PSPS program information. 

Hours, availability, and services vary by event.

A resource center is not necessarily an overnight shelter or a facility equipped to support every medical need.

Check the center’s address and available facilities before setting out. 

Can Solar Panels or Generators Keep Your Home Powered?

Standard grid-connected solar panels usually shut down during a grid outage unless the installation includes properly configured backup capabilities.

A compatible battery storage system and approved electrical equipment may provide backup electricity.

Portable generators offer another option but must be operated safely.

According to the CDC, generators should be operated outdoors, with a minimum clearance of 20 feet from windows, doors, and air vents.

Never operate a generator inside a home or garage, and never connect one directly to a household wall outlet.

Use approved equipment installed according to applicable electrical requirements.

Essential MilitaryKart Gear for PSPS Emergency Preparedness

A California wildfire power outage kit should help households maintain lighting, communication, organization, and basic comfort.

The following MilitaryKart products address common challenges during a planned electricity shutoff.

1. Ultimate Power Outage Kit – 72-Hour Blackout Bag

The MilitaryKart Ultimate Power Outage Kit brings together several useful emergency tools.
