More than 300 homes in Dereham and the surrounding area have been left without power.
A power cut originally affected 670 homes in the area between Great Fransham, Bittering and Brakefield Green.
After rerouting electricity in the area, the issue is affecting 322 homes.
It has been caused by an underground electricity cable faulting within the network.
UK Power Networks has dispatched engineers to the scene where they will work to solve the issue.
The company estimates the power will be back on by 10.30am.
