Engineers are working to restore power to more than 7,000 homes that were cut off after yesterday's storms.
Northern Power Grid says 7,337 homes remain without electricity, down from 23,000 immediately after the flooding and lightning storms. It says those affected will have their power restored "as soon as possible."
It says the cuts happened after electricity substations were flooded, and restoring power took longer than normal because of traffic congestion caused by the rain.
The worst affected areas are Consett and Stanhope in County Durham, and Alnwick in Northumberland.
The Environment Agency has issued flood warnings for the North East after flash flooding yesterday afternoon.
People in properties and low lying areas near Smallhope Burn at Lanchester are being warned to take action.
And a Flood Warning is still in force for the Ouse Burn at Woolsington and Brunton Park. This means that flooding of homes and businesses is expected.
Flash flooding has caused havoc across the region. Storms swept in from the west on Thursday afternoon, leaving roads underwater, homes flooded and people stranded.
Roads were gridlocked in towns and city centres.
Northern Power Grid say they are working to restore power to an estimated 13,000 homes in the region.
