Around 20,000 homes and businesses were without power in Dublin following an electrical fault earlier.
A spokesperson for the ESB said the fault was caused by a cable fault near Finglas.
The outage was first reported at 6.30pm and power was restored around 10.30pm.
Affected areas included Palmerstown, Finglas, the greater Blanchardstown area and other smaller pockets of north Dublin.
ESB apologised for any inconvenience caused.
