Rolling blackouts occur when delivery of electricity from a large power source is intermittently stopped in varying places across a wide area. Rolling blackouts usually occur in tandem with natural disasters or energy crises.

Rolling blackouts prevent large power sources from blacking out completely. They have been implemented in places with a high demand for electricity, such as Japan, the U.S., Pakistan, and Ukraine.

By limiting the amount of power that can be used at one time to only certain areas, power station operators can control the power output from their generators. Should a part of the generator be at risk for failure, operators can begin a rolling blackout to limit the amount of work the generators must do. From there, they can pinpoint the problem areas and find a useful fix without taking away power from an entire area.

Rolling blackouts can prevent power outages from:

In the case of power output problems like station faults, short circuits, and electrical overloads, a rolling blackout can mitigate the risk of explosion and prevent the acceleration of large scale disasters.

Since power can only be distributed over a limited area, 100% of the electricity supply to some places will be temporarily cut off. Household items such as lights, outlets, and appliances will cease operation for a predetermined amount of time. You can gather information about rolling blackouts from the radio or news before they occur.

You should have an emergency kit in your home or business that has the necessary supplies for survival without electricity. Items to include in an emergency kit are:

Be sure to lock all of your doors and windows if possible. In developed countries, law enforcement will bolster its forces to protect areas affected by a rolling blackout. You should still remain safe and prepared whenever possible.

Should a rolling blackout elevate to a blackout, don’t be afraid to use your supplies. Even if electrical generators are running at low capacity, they still have the potential to cause larger problems should they become overloaded. A rolling blackout can quickly become a city-wide blackout.

Rolling blackouts are relatively rare. Conditions must be extreme for a rolling blackout to take effect. While the climate in the U.S. varies widely across the country, devastating natural disasters don’t compromise the electric grid more than once every 20 years.

We’re barely a week into fall and the temperatures are already dropping and the stormy season is upon us. Here in Virginia, we’re bound to get our fair share of severe thunderstorms, which always carry the potential of a power outage. Because September is National Preparedness Month, we thought we would help you prepare ahead of time for a power outage, should one happen in your neighborhood.

We often forget how important it can be to call an electrician if a problem arises with a home’s electrical system. In fact, most homeowners are complacent that their wiring system is just fine and needs no care or maintenance. More often than not, the only time a licensed electrician is called to a house when something is going wrong. It’s important to understand how to recognize when you may need to be preemptive about electrical problems and subtle signs that your electrical system needs maintenance or repairs. Keep an eye out for the following issues that could arise, indicating a bigger electrical problem in your home.

If you’re a fan of power strips, that’s not necessarily a problem right away. The problem happens when you start to overload a specific circuit in your home. Attaching a power strip and then packing it full of energy-heavy devices can quickly cause circuit breakers to flip. In addition to that risk, they can quickly become a fire risk when used inappropriately. Opt for power strips with surge protectors and be careful concerning how much you plug into them. If you need more outlet availability in a space, that’s when you need to call a local electrician.

While the rugs themselves aren’t a sign of electrical problems, the wires and cords run under them are. More and more people are adapting older homes to their current needs, leaving exposed cords and cables throughout the house. You don’t need to run them under carpet and rugs. In fact, that can be a tripping hazard. An electrician can quickly run wires and cables through the walls to get the cables out of sight and out of mind.

If you own an older home, you may have noticed how your outlets don’t look quite like outlets in newer homes. For a long time, two prong outlets were the standard. No many appliances use a three prong plug style in order to provide a ground for the electricity. Don’t be someone who just cuts the third prong off of their appliances or bends it back to make it fit in the two prong outlet; upgrade your outlets instead. Properly grounded outlets can reduce the risk of electrical fires and other risks due to electricity.

It’s important to regularly check your home’s main service panel. Regular visual checks and professional checks by an electrician can help to prolong the life of the panel and help avert any problems from improper care. When you visually inspect the panel, check for any signs of problems, including potential rust. If your panel is rusting, it’s time to have an electrician install a new one for safety and performance.

If you’ve ever turned on a light switch and found that the plate was warm to the touch, then you should call an electrician. Points where power is utilized in the wall should never be warm, and definitely not hot. It’s a sign of a bigger electrical problem that could be a safety hazard.

How old is your home or business building? 20 years? 30 years? 40 years or more? When was the last time you had your wiring inspected? If your building is older than 25 years, you could be at risk for an electrical fire. Electrical fires are frequently caused by old components wearing out and failing, but these things can be hard to detect since so much of it is hidden from sight behind your drywall. So how do you know if you are at risk? Here are a few factors that frequently cause fires in older buildings.

From the 1880s until the mid-1930s, knob-and-tube wiring was the standard in running electricity lines through homes and businesses. Today, these systems are not permitted under business code except in extremely rare circumstances. If your home or business has this old system of wiring in it, odds are you should consult an electrician about replacing it with a modern system as soon as possible. Rodents have a thing for chewing on these exposed wires, making them tremendous fire hazards.

Modern appliances and equipment sometimes require a much higher amperage draw to function than old wires are rated to carry. When you overload a wire with too much amperage, it can get extremely hot, which can start fires inside your walls. If your electrical system is old, consider having it inspected by a professional who can tell you whether or not you should upgrade to wire rated for a higher amperage.

Part of being a home or property owner is improving your property. Those who have a knack for handiwork (or at least think they do) may have tried to modify their wiring in the past. This means there could be shoddy connections, loose live wires, and other serious fire hazards hidden behind your walls. Be extremely careful when cutting into drywall in an older home.

Over time, insulation on wires can age, become brittle, and crack. In other cases, the wires may have been chewed by rodents or screwed or nailed into by accident. This can leave the core of your wire exposed, which leaves it prone to sparking and potential fires.

The wires aren’t the only part of your home that’s at risk for starting a fire; old breakers can malfunction and overload if they are not maintained or upgraded every few decades. Have your old circuit breaker inspected by a professional who can test to make sure everything is still functioning properly, as well as replace any breakers that may not be working correctly.

Today’s electrical code is far more advanced and rigorous than it was in decades’ past. With new technology has come new safety standards. However, older buildings were not required to adhere to these new standards, and many of them have not been properly retrofitted with the latest in electrical tech. Odds are, if you have an older building, your electrical system would not pass inspection today. Let a professional take a look and work with you to eliminate the fire hazards and protect your property from a devastating fire.
