More than 300 homes remain without power from the southern end of Eden to the Victorian Border.
Essential Energy said repairs were ongoing and efforts being made to reconnect all their customers as quickly as possible.
However, an update on Tuesday said that a number of energy assets had been damaged by the border fire and were impacting restoration efforts.
Some homes were reconnected around Pericoe and Towamba on Monday.
The company said access to parts of Nullica was impossible with active fire areas inhibiting work.
The majority of those left without power remain in the Kiah, Edrom and Wonboyn areas with 224 homes still without power.
The current timeframe from Essential Energy is that homes will not be connected before January 20.
