Why Do Power Outages Happen?
Before answering “How long do power outages last?”, it’s important to know what causes them. Understanding the root of the problem can give you insight into how long it might take for the lights to come back on.
Common Causes of Power Outages
- Severe Weather – Freezing rain, ice storms, snow, and high winds can damage power lines. In British Columbia, windstorms and heavy rainfall are the most frequent culprits.
- Equipment Failure – Transformers, substations, and underground cables sometimes fail due to age, overheating, or mechanical damage.
- Grid Overload – Extreme heat waves or cold snaps cause higher demand for electricity, leading to outages when the grid can’t keep up.
- Scheduled Maintenance – Utilities occasionally shut down sections of the grid for repairs or upgrades. These outages are usually short and announced ahead of time.
- Accidents & Wildlife – Vehicle collisions with power poles or curious animals getting into electrical equipment can cause localized outages.
How Long Do Power Outages Usually Last?
The duration of power outages varies greatly depending on the cause:
-
Minor Outages: 30 minutes to 2 hours (often caused by small equipment failures or local accidents).
-
Weather-Related Outages: 6 hours to several days (storms may bring down multiple lines, requiring extensive repair).
-
Severe Events: Up to several weeks (after hurricanes, wildfires, or ice storms).
-
Planned Outages: Typically 1–4 hours (utilities notify customers in advance).
Key Tip: Always check your local utility provider’s outage map or app for real-time updates on restoration estimates.
What to Do During a Power Outage
When the lights go out, staying calm and taking the right steps can make a huge difference.
Immediate Actions
- Check Your Home – Look to see if the outage is only affecting your property. If your neighbors still have power, check your breaker panel before calling the utility company.
- Turn Off Appliances – Unplug major appliances, tools, and electronics to prevent damage from power surges when electricity is restored.
- Leave One Light On – This acts as a signal to let you know when power is back.
- Preserve Food – Keep refrigerator and freezer doors closed to maintain cold temperatures. A full freezer can stay cold for about 48 hours if unopened.
Safety Precautions
-
Avoid Carbon Monoxide Poisoning
Never use charcoal grills, gas stoves, or generators indoors. Always run generators outdoors, at least 20 feet from windows and doors. -
Use Candles Safely
Opt for battery-powered lanterns, but if using candles, never leave them unattended and place them in sturdy holders. -
Monitor Updates
Keep a battery-powered or crank radio on hand for official updates. -
Protect Devices
Use surge protectors for electronics like TVs and computers.
Preparing for Extended Power Outages
Some power outages are resolved quickly, but severe ones can last days. Preparing ahead of time ensures you’re ready.

-
Flashlights & extra batteries

First-aid supplies

Invest in Backup Power
Consider installing a home backup generator or portable generator. This keeps essentials like heating, refrigeration, and communication devices running.
Communication Plan
Have a way to contact family members if cell service is interrupted. Text messages often work better than calls during network strain.

Minor outages often last under 2 hours, while storm-related outages can take 6–48 hours or longer depending on the severity.

Check your utility company’s website or outage map. Many companies also provide real-time text or app alerts.

Use your emergency kit, conserve battery power, and consider relocating to a warming or cooling center if conditions are extreme.
