UK Power Networks has apologised this morning after cutting the supply to 172 customers in the Hempton area following a fire caused by an overhead cable fault.
The company said engineers are working as quickly and safely as possible to restore the supply following a fire near the driveway through to Fakenham Racecourse at 5.27am.
A spokesman for UK Power Networks said: 'The fault originally affected six customers but in order to carry out emergency repairs we had to isolate power supplies to a further 172 customers at 10.40am.
'We appreciate how difficult it is to be without electricity and apologise to all those affected.'
The spokesman said that he fully expected the electricity supplied to be restored at some point today.
He was unable to confirm, at this stage, what caused the fire or more details about it.
Neither Fakenham Racecourse or Fakenham Sports Centre have had their power cut off.
Fire fighters from Fakenham attended shortly before 9am to make the scene safe.
A spokesman for Norfolk Fire and Rescue Service said that an ambulance was not requested and nobody was harmed.
