A fire at an ESB substation has left thousands of customers in Dublin without power this morning.
The blaze broke out in the early hours at a transformer on Brewery Road in Leopardstown.
10,000 subscribers have already been reconnected but it still leaves 10,000 customers without service around the Mount Merrion area.
Meanwhile a fault in Limerick will leave 130 customers without power until this afternoon.
And another fault in Belmullet in Mayo should be fixed within the next couple of hours to get over 200 customers back on the grid.
