Endeavour Energy crews are continuing to safely restore power to 2100 homes after Sunday's damaging winds.
As of 11am, the bulk of customers yet to have power restored live inOak Flats (55) and Dunmore (52).
Power should be restored to all customers by Monday afternoon if weather conditions remain calm.
At the peak of the windstorm mid-afternoon Sunday, more than 57,000 customers were without power as Endeavour Energy crews responded to more than 540 electrical hazards caused by trees and branches blowing over powerlines.
Customers without power on Sunday night received direct messages with safety information and updates on estimated restoration times, the provider said.
"The issue is today it's a Total Fire Ban, so all the devices that normally withstand this tree contact [with the power lines] are all turned off for safety reasons," Endeavour spokesman Peter Payne said.
"This is quite abnormal ... we're in for a rough night."
He said the cool change coming Sunday evening, it could make matters worse.
Endeavour Energy crews will patrol the damaged parts of the network before making it safe and starting repairs.
Under total fire ban conditions crews need extra time to complete this work safely, so Endeavour said it's not possible to give an estimate of the time it will take to restore power supply to affected customers.
Power outages were also affecting traffic lights at the corner of Lake Entrance and Wattle Roads in Blackbutt, and Princes Highway and Colden Drive in Albion Park Rail.
Meantime, motorists are advised a fallen tree has been reported down on Five Islands Road near Flinders Street at Port Kembla.
Other areas experiencing power outages on Sunday are:
Sanctuary Point, Bundanoon, Box Hill, Bawley Point, Kiola, Basin View, Nowra, Wilton, Worrigee, , Glenorie, Callalla Beach, Callalla Lake, Lake Tabourie, Kurrajong, Falls Creek, Kangaroo Valley, South Nowra, St Georges Basin , Glossodia, Exeter, Fitzroy falls , Fishermans Paradise, Termeil and Berry.
