“We may need to take some customers off supply this morning to facilitate permanent network repairs but we hope to have electricity restored to the majority of homes by lunchtime.
“We would like to remind customers that if they do lose electricity supplies they should contact the NIE Customer Helpline on 08457 643 643 or report the fault online at nie.co.uk.”
