Some 1,375 properties, mainly in Margate and Westgate, have been affected by a power cut today (November 7).
The outage is due to an underground cable that has faulted.
It affects properties in the CT8 8,CT9 5,CT9 X and CT9 4 areas of the isle.
Engineers are currently at the scene to repair the fault.
It was reported to UK Power Networks at 10:44am. Estimated time for the power to be back on is between 12.30pm and 1.30pm.
One resident said it is causing “chaos” in Margate with “shops closing, cash points non working and Coffin Corner traffic lights out- chaos.”
UPDATE: 258 homes now affected. A UK Power Networks spokesman said: “Engineers are working quickly to restore electricity supplies to 259 properties in the Tivoli Road area of Margate and 39 customers Westgate-on-Sea after a fault on the electricity network at 10.45am today.
“We apologise for any inconvenience caused and work is progressing to reconnect all supplies.”
UPDATE: (1pm). The 39 properties in Westgate went back on supply at 11.59am and the final customers in Margate had power restored between 12.20pm and 12.30pm.
UK Power Networks says the power interruption initially affected several thousand customers at 10.45am, but most supplies were restored quickly in stages within an hour.
