A blackout is an entire interruption in utility grid power that may last for minutes, hours, or days. The more prolonged outages are most likely to result from natural disasters that damage power lines as well as other infrastructures of the grid. Before we begin the show of hands. Which one of our readers has seen the iconic 1968 Doris Day film Where were you when the lights went out? Okay, we wanted to confirm that we weren’t the only ones! The movie was filmed within New York during the infamous Northeast Rolling Blackout that occurred in November 1965 when more than 30 million residents throughout seven U.S. states and parts of Canada were without power for more than 14 hours.

What can cause an electrical blackout?
The 1965 northeast blackout was due to a defective relay. The power failure caused chaos across the region. The lights on the road failed, and a grid lock erupted. Many were stuck in subway and elevator trains. Everybody was in darkness, in various and sometimes dangerous circumstances.
Blackouts can result from numerous other causes other than a defective relay. Examples include damaged transformers, lightning storms that down trees that fall onto power lines or ice accumulation on power lines. In addition, things like high temperatures in triple-digits can lead to blackouts.
Outages can occur when power demands are pushed over the limits of the grid, causing it to malfunction. When tens of thousands of AC units are on and start drawing electricity to make people slightly comfortable, it overwhelms power grids.
How do you define a Brownout?
Another concept to keep in mind is brownout. A brownout isn’t a total power loss, but rather is a decrease in electricity going to the grid. consider it the result of a voltage drop. In order to make it clear the main difference between brownouts and blackouts is: A blackout is a total grid shut down, while the term “brownout” refers to a temporary outage or a flow reduction.
Consider a brownout similar to the dimming you experience when lighting caused by a voltage drop. Brownouts reduce the power available from the grid, ranging between 10 and 25 percent. Instead of the power grid being shut off completely its capability (its power flow) is diminished.
Are my electronics damaged by brownouts, blackouts, or blackouts?
Appliances can be utilized during a brownout , however dependent on the equipment, it is not recommended due to the fact that during a brownout voltage will fluctuatewhich could cause damage to our most sensitive electronic devices.
If a device requires the exact amount of power in order to operate it, then the sagging and surge of energy that occurs in a brownout may harm smart devices like computers TVs, smart refrigerators and so on. Other appliances that are sensitive shouldn’t be used as even though they are capable of functioning however, there is an increased chance that their circuitry may be damaged.
It is also important to be aware that if power comes back on following an outage, it could harm delicate electronic equipment.
Then, what is an e-blackout that is rolling?
An rolling blackout a technique which electric providers can employ to avoid the spread of power outages in extreme heat periods (with the potential for wildfires) or during extremely colder times (with the possibility of large snow/ice loads as well as trees falling, which could cause damage to power lines).
Blackouts caused by severe weather or storms are completely unavoidable — and consumers are unaware that they’ll be without power rolling brownouts, also known as rolling blackouts, are usually planned by utility companies to alleviate the demand pressure on the grid in order to ensure a full and complete blackout.
In an ongoing brownout or blackout, utilities, who have designed these power cuts and power interruptions, are aware precisely how long the power is out and when it is restored to normal.
Why do utilities deliberately design a blackout that is continuous?
Utility companies utilize rolling brownouts and rolling blackouts specifically to lessen load and avoid the possibility of a serious blackout. If the utility company anticipates that there will an enormous increase in electricity usage that could overload the grid, they make the grid power unavailable for a short time until the threat of overload is over.
Also the rolling blackouts (or brownouts) are outages that are temporary in nature which are planned for certain regions to conserve electricity and safeguard the grid. This is to ensure that supply is balanced with demand for electricity on the market. In general, if the national grid or the regional grid is calling to have a blackout that rolls the local electricity provider will be able to conduct intermittent outages in specific areas for a specified period of time.
It “shares the pain” so to speak. This means that rather than letting an zone be left in power outages for long enough, they’ll shift or roll the power outage from one location to the next to minimize the harm that being in power for an extended time could result in. In the event of a planned roll-out brownout or blackout, there’ll be an advance warning or announcement so that people can be prepared for the eventuality.
Who decides on the schedule for the rolling blackout?
The electric utility will decide the areas that will be affected by the intermittent blackouts. Certain areas are not affected as severely as other areas due to their power-sensitive needs, such as downtown areas which typically have higher-rise buildings with elevators, subways, hospitals and medical clinics in which power could be the difference between life and death.
Sometimes the utility will issue an “power alert” request to solicit its customers to attempt to cut down on their consumption of power, thereby avoiding grid overloads during high demand times. Because we are a society of consumers that like to think about our neighbors and neighbors, this power alert can be enough to prevent the possibility of a cascading blackout.
How long will the blackout that rolls out last?
The conclusion is that these scheduled rolling outages , or power cuts even though they can occur regularly typically last only for a brief period and within a specific area. They after that, they “roll” on to the next region.
If you receive the letter from your utility that says your area is going to be without power for several hours at a specific date and time, and advises you to unplug electronics that are sensitive, be aware of. The reason that the utility suggests unplugging electronic equipment that is sensitive is that if your power comes back to full power during a roll-out brownout, or when it is restored after a rolling blackout , it could damage the circuitry of delicate electronic gadgets.
Why do we experience perpetual blackouts?
As we have discussed, rolling blackouts can be utilized by companies that provide utilities with the ability to control peak demand. They can be used to stop your grid from malfunctioning in the event of the load of peak usage to avoid a prolonged and more permanent blackout.
Blackouts with rolling blackouts occur when the supply of electricity is inadequate when compared to demand. Extreme temperatures or cold could create an imbalance in demand and supply of electricity. This means that temporary blackouts could help keep the area affected from suffering a prolonged blackout.
The states that are more populous and warm such as California or Texas employ rolling brownouts as well as rolling blackouts in order to stop excessive demand during extreme heatwave conditions to guard their grids from a devastating shut down. It’s similar to blowing off steam to stop the boiler from accumulating too much pressure and eventually exploding in the event of an explosion, and so one could consider this technique to be utilized as a security valve to prevent the grid from sustaining catastrophic cascading malfunction.
Additionally, in California in the fall and summer months, wildfire season , rolling blackouts are regular occurrences as utility companies have begun to close their power lines to avoid sparking wildfires. (We have, in the last several years here in California and elsewhere, lost huge sections of rural communities to wildfires that were reportedly caused by electric cables.) So, shutting off power completely is a strategy utility companies are currently using to minimize the risk of wildfires during extreme windy or dry weather.
In colder regions, such as certain northern states, being able to have electricity to warm your home in the event of an outage could be a better option than having to face the cost of burst pipes or frozen pipes.
As a nation , we’ve set new goals to improve the infrastructure of our country that involves increasing the capacity of electric grids. Although officials strive to increase the reliability of grids it will not be able to stop an unexpected and sudden loss of electricity. The reason is that when demand reaches the highest levels, there’s insufficient capacity for the grid to handle this demand. Insufficient electrical grid infrastructure to handle the current peak hour demand.
Our grids of electricity were not built to handle the type of load we put on them. The population has been growing, but the amount of electricity that modern homes use is above what our grandparents could have ever imagined.
We have a myriad of electrical gadgets that weren’t there when our grandparents were children. Televisions, air conditioning dishwashers, microwave ovens, laptops, computers, printers tablets, cell phones, to name some, and all of these require power to function.
Although our energy use has increased over time but it’s still peak usage times that strain the grid.
As the demands for energy increase due to the growth in the population and the growing amount of electronic devices we own, blackouts that are rolling becoming more frequent. It’s not uncommon today that every household member possess a phone tablet, laptop television, and/or computer.
Due to the fact that it’s peak hours of usage that could trigger blackouts, several utilities in states have enacted Time of Use electricity rates to help reduce the strain of sudden peak usage on the grid.
The most frequent use of devices is between 4 PM until 9 PM, when the kids return home from school and parents return from work. Suddenly, hundreds of devices are lit up in a type of cataclysmic power surge that sees everyone turning on air conditioners lighting, televisions, and computers to ensure their homes are comfortable while they relax for the night and begin making dinner.
What can we do as individuals to prevent blackouts?
Since extreme weather conditions could result in a higher consumption of electricity, the most effective way in order to aid is reduce your personal consumption of electricity. Below are some guidelines to prevent blackouts. Unplug appliances not in use. Use energy-efficient LED bulbs. Set your thermostat higher when the temperature is high. Reduce the temperature of your thermostat when the temperature is low.
Ceiling fans can be used to draw warm air downwards as well as draw up the warmth, by setting them in the winter clockwise direction and counter-clockwise during summer. Fans will improve the flow of air and decrease your requirement for powerful heating or air conditioners.
