Power has now been fully restored to Murrurundi.
The broken cross-arm was caused by a lightning strike during last night's storm that ripped through the region.
Murrurundi is without power.
Essential Energy say the power has been switched off to nearly 2,000 homes after a broken cross-arm was identified between Quirindi and Murrurundi.
Crews are working as quickly as possible and as safety as possible, to get the repairs completed.
The power should be restored by 1pm.
