Power workers finished fixing an underground cable on Wednesday lunchtime, five days after a fault left nearly 300 north Norfolk village homes without electricity.
UK Power Network engineers had to put in a section of new high-voltage cable at Southrepps.
All 282 customers had their electricity restored in stages on March 16, the day the fault occurred, but 118 of them have been receiving supplies via a generator during the repairs.
A UK Power Network spokesman apologised for any inconvenience and said the repair had been complex.
