Yes, it could happen: grid down. From Madge Waggy at sevenwop.home.blog:
(It may be an over-statement to refer to the U.S. power grid as crumbling, but in many parts of the country that’s exactly the case. The North American power grid is old.)
Many of us have experienced a power outage at one time or another. Most of the time the duration of the outage is measured in hours, maybe a day, and in rare instances – a week or more.
The outages also tend to be localized and repairs happen quickly or power is “borrowed” from a nearby utility or network and rerouted to the affected area. The experience is usually a frustrating inconvenience and most hospitals and critical systems have backup power to get through the outage.
But what if…?
What If The National Grid Fails?
It’s never happened in the United States, but some countries have had widespread power outages affecting most of their territory. Russia’s cyber attack on Ukraine’s grid in 2015 knocked about 60 substations offline, leaving 230,000 people in the dark. It was an ominous threat, but once again, the outage only lasted 1 to 6 hours.
It seems like most power outages, regardless of the extent, have a short duration and are only an inconvenience. But there’s a problem.
