Today’s Parola del giorno is the noun il black out.
It is often written without the space as il blackout.
The word means blackout, a condition in which there is no electrical power due to a power failure of some kind.
You could also say un’interruzione della corrente elettrica, which is a bit longer and perhaps less colloquial.
See the expression used below:
