Top Power Outage Duration Statistics

These are some of the most critical power outage duration statistics:

  • US citizens experienced an average of seven hours of power interruptions in 2021. 
  • Louisiana had the longest average power interruption in 2021 at 80 hours
  • Maine had one of the lowest amounts of power interruption in 2021 at just above 3 hours
  • Hurricane Nicholas Left Over Half a Million People in Texas Without Power.
  • Squirrels Cause Up To 30% Of Power Outages. 
  • A winter storm in Texas left 4.5 million Americans without power in February 2021. 
  • Storms, including hurricanes, caused most power outages on the Atlantic seaboard. 
  • Brownouts Can Also Occur During a Power Outage.
  • Oregon experience power outages due to hot and cold weather events in 2021. An ice storm in February and the Bootleg wildfire in August 2021 caused power outages. 
  • Louisiana experienced a hurricane in 2021. Hurricane Ida left 1.2 million people without electricity. The outages lasted for up to two weeks. 

Hurricane Nicholas Left Over Half a Million People in Texas Without Power. It Also Impacted Mississippi and Louisiana.

Power outages caused by natural disasters like hurricanes highlight the resilience or vulnerability of the power infrastructure in the affected areas. 

Brownouts Can Also Occur During a Power Outage.

These happen when there’s still a little power available.

Squirrels Cause Up To 30% Of Power Outages. 

If they run over or chew wires, power outages can occur. 

If Your Power Is Out for Less Than 4 Hours, the Food in Your Refrigerator and Freezer Will Be Safe. 

Consuming spoiled or contaminated food can pose health risks, including foodborne illnesses caused by bacteria, viruses, or toxins. Understanding the timeframe within which food remains safe during a power outage can help prevent individuals from consuming potentially harmful food and avoid related health issues.

The Biggest Power Outage Left 55 Million People With No Power.

It spanned several states and Canada.

When the Power Goes Out, Water Prification Systems Will No Longer Function Properly.

If your electricity is out for any period of time, you should boil your water until the government gives you the go-ahead to drink from the tap again. 

You Shouldn’t Use a Gas Stove During a Power Outage.

Doing so could accidentally cause a fire. 

If Your Power Is Out for Over a Day, You Should Discard Any Refrigerated Medication

Some individuals rely on refrigerated medications for critical health conditions. For example, patients with chronic diseases, such as diabetes or autoimmune disorders, may need refrigerated medicines like insulin or biologics. Discarding these medications after a prolonged power outage emphasizes the importance of having contingency plans and alternative sources of medication available during emergencies.

The CDC Recommends Having a Disaster Supply Kit During a Power Outage. 

Being prepared for such situations is essential to ensure the well-being and safety of individuals and their families. The CDC’s recommendation emphasizes the importance of having a disaster supply kit for emergency preparedness efforts.

New York City and Chicago Power Outages Are Longer In Winter and Spring.

Winter and spring are seasons known for challenging weather conditions in many regions, including New York City and Chicago. Factors such as heavy snowfall, ice storms, freezing temperatures, and strong winds can increase the likelihood of power infrastructure damage, leading to prolonged outages. 

One of the Most Significant Contributors to the Length of a Power Outage Is the Age of the Circuit Breakers.

Circuit breakers are crucial components of the electrical distribution system. They protect electrical circuits from overloads, short circuits, and other electrical faults. Over time, circuit breakers can deteriorate, become less reliable, and fail to function correctly.

Experts Can Now Model the Length of Power Outages Due to a Hurricane With up to 87% Accuracy

Accurate modeling of power outage durations allows authorities, emergency management agencies, and utility companies to better prepare for and respond to hurricanes. 

A Person’s Ethnicity and Rent Are Two of the Strongest Indicators Determining the Length of a Power Outage in Texas.

Power outages disproportionately impact minorities and people lower on the socio-economic scale. 

Rural Electric Cooperatives Experience More Prolonged Power Outages; Restoration Takes up to 3X as Long in Florida

Rural areas often have dispersed populations and expansive territories, making it more challenging to maintain and restore power infrastructure. 

You Should Only Use a Generator Outdoors.

This is to keep you safe. 

Smart Grid Funding Can Reduce the Length of Power Outages by up to 50%.

Smart grid technologies facilitate automated restoration processes, reducing the need for manual intervention and allowing for faster response times. With automated systems, the grid can self-heal by rerouting power and isolating faulty sections, minimizing the duration of outages and reducing the overall impact on customers.

The Average Californian Should Have Backup Power That Lasts Between 2-6 Days

California experiences power outages for various reasons, including wildfires, extreme weather events, and planned utility shutoffs. These outages can vary significantly, ranging from a few hours to several days. 

90 People May Have Died During America’s Longest Blackout.

Experts put this down to disease rather than accidents. 

Check That Your Carbon Monoxide Alarm Is Working During a Blackout.

Dangerous Carbon Monoxide leaks can occur in a blackout, so it’s important to check your alarm is working. 

Wildfires Are Projected To Be California’s Leading Cause of Power Outages by 2026.

California has experienced a significant increase in wildfire activity in recent years, driven by climate change, drought conditions, and forest management practices. Unless climate change policies are enacted, California will continue to struggle with power outages well in the future.
