What Does Power Outage Mean?
A power outage is a short- or long-term state of electric power loss in a given area or section of a power grid. It could affect a single house, building or an entire city, depending on the extent of the damage or cause of the outage.
Techopedia Explains Power Outage
Power failures in an electric network can be caused by different factors, but the most common are often faults in the power lines and in the distribution stations themselves. Only very rarely are the power plants themselves at fault since these systems are built to withstand minor disasters and have various backup facilities that kick in when the main system goes offline for some reason.
