A power outage (also called a powercut, a power out,a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user.There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substation.

In , the power generation and the electrical load (demand) must be very close to equal every second to avoid overloading of network components, which can severely damage them.

Computer systems and other electronic devices containing logic circuitry are susceptible to data loss or hardware damage that can be caused by the sudden loss of power. These can include data networking.
