Energy networks have urged the thousands of households still without power following Storm Arwen to seek alternative accommodation if possible, warning that some individual homes or groups houses may not be reconnected until after Tuesday due to localised faults. The Energy Networks Association said supplies had been restored to over 90% of affected customers by 5pm on Monday evening (29 November) but more than 66,000 remained disconnected as engineers battled the elements to repair severe damage to overhead power lines.
