Why are they doing rolling blackouts?

We all share energy, and when a grid isn’t adequately protected against potential overloads, it causes damage that results in a complete shutdown. 

Your eclectic company will cut off one part of the region and then another and another for a few hours at a time.

Ideally, a rolling blackout will protect against an overall failure of the grid and come with some notice.

How long does a blackout last?

The unpredictability of blackouts makes it hard to gauge just how long they will last. It could be one hour, or it could be three.

While utility companies try to alert customers, excessive demand can happen in a split second, and they must take fast action.

The entire process of initiating a blackout depends on where you are in the country. In most regions, the regulator for electricity orders them once they’ve detected a problem. According to law, the utility companies must comply.

Brownout vs Blackout vs Rolling Blackout

  • Brownout. A utility company uses brownouts in an attempt to prevent a total blackout. A common solution is to cut overall voltage by 10-25%, and they give you some sort of timetable.
  • Blackout. Blackouts sometimes happen with zero notice and can last an undetermined amount of time. It is why preparation is vital during extreme temperatures.
  • Rolling blackout. A utility company will give customers a notice that they are performing rolling blackouts to prevent a complete blackout. They usually last 1 to 3 hours.

How do you survive a rolling blackout?

The thing about rolling blackouts is the high possibility they will lead to a complete longer-term blackout. And you should prepare for a rolling blackout just like you would prepare for any power outage.

Think About Evacuation

Rolling blackouts happen during extreme weather, so evacuating is necessary for some. For others, the uncomfortable extreme heat or cold sends them elsewhere.

Either way, it is best to plan where to go in the case of any type of blackout. It will include how to move pets, people, and other essentials.
