More than 15,000 houses that were left without electricity after a fire at a substation have had power restored.
The fire that broke out at an ESB substation in Clondalkin early on Sunday damaged components of the substation, leaving some ESB customers in the area without electricity for around 15 hours.

Although the fire was relatively small, a Dublin Fire Brigade spokesman said the damage "could be immense".
The ESB had managed to restore power to most customers yesterday.
Houses in neighbouring areas were urged not to use non-essential electrical appliances while repairs were taking place, and electricity workers installed stand-alone generators yesterday evening.
ESB spokesman Mr Kevin MacDermott said that repairs to the substation's components may take some time. He added: "We're hoping there will be no further problems for our customers".
