Homes face over 24 hours with no power
Households, farms and businesses face being without power for more than 24 hours in the aftermath of Storm Emma.
Downed power and telecommunications lines have left tens of thousands without a service, while Irish Water has warned of potential drinking water shortages in some areas.
Damage wreaked over the past number of days left at least 34,000 homes, farms and businesses without power, with the ESB warning that new faults were emerging, particularly across Enniscorthy, Arklow, Portlaoise and Cork.
"Due to these faults, access issues, and worsening weather in the south east, it will be tomorrow at the earliest before some customers will get electricity back," it said in a statement.
"Cork, Enniscorthy, Arklow, the Greater Dublin Area and eastern counties of Leinster are the main areas affected. We understand how difficult it is to not have electricity in these conditions and so our staff are focussed on trying to restore supply to as many people as possible as quickly as possible.
"There are deep snow drifts in various parts of the country and so it is taking our crews a very long time to travel to each fault. It is also more difficult than normal to then carry out a repair."
Eir said that 10,000 customers were without a service.
Irish Water has warned of possible supply problems in Mayo, Cavan and Cork as treatment plants struggle to meet demand, while customers in Galway have been asked to conserve water.
Around 1,000 people served by the Fardystown Regional Water Supply Scheme in Wexford were without supply after a pipe burst, while a number of boil water notices have been imposed on smaller schemes.
