We're hearing a number of areas in North Derbyshire have been affected by power cuts.
Homes and businesses in Chesterfield, Matlock and other surrounding areas were left without power, affecting thousands of homes across the region.
Western Power Distribution have told us they they believe it to be a national grid problem
We are currently experiencing a major incident on the national electricity infrastructure. We are in the process of restoring customers now and will provide further updates as soon as possible for specific areas We are sorry for the inconvenience this is causing.— WPD (@wpduk) August 9, 2019
