11.45pm UPDATE: Dozens of homes and businesses from Weston Street to Tower Bridge Road were without electricity for several hours on Sunday night after a fire at a substation in Tanner Street.
Firefighters dealt with the fire which damaged 5 per cent of a ground-floor electrical substation and handed over the premises to EDF Energy to allow them to reconnect the supply.
Other businesses affected by the power failure included the convenience store on Snowsfields.
Power was restored to some Tanner Street homes at about 9.30pm.
Update 11.45pm: Cllr Mark Gettleson (Grange ward) says EDF Energy has told him that 1,000 homes are still without power. Supply will be restored overnight as and when it is safe to do so.
