Our emergency crews will continue to work where it is safe to do so.
We were prepared for the storm and have already restored over 5,000 customers to power since the winds swept across Northern Ireland this afternoon.
However, we are expecting the winds to peak in the early hours of the morning, causing additional disruption to electricity supplies.
Strong winds have already wreaked havoc with the supply network in Northern Ireland, leaving 7,000 electricity customers without power.
Engineers managed to get 5,000 back on the grid, but by 10pm were still working to restore supply to the remaining 2,000.
