10,600 homes and businesses around County Waterford remain without power this morning.
Power was restored to 10,500 homes during the course of yesterday.
The ESB said 25 network technicians arrived from Dundalk to assist crews in Waterford on Tuesday and more staff are coming from Wales today.
The 10,600 homes without power are scattered throughout the county, and the border with south Kilkenny and south Tipperary.
