The bushfires have hit the electricity network so hard that Endeavour Energy has had to ask around for more power poles.
And they haven't been able to replace the burned wooden ones in bushfire-prone areas with steel poles - because they've run out.
As of Wednesday, more than 450 power poles had been burned across the Endeavour Energy coverage area since December.
"Burned poles have been located in the Southern Highlands, the Upper Blue Mountains and Lithgow area, and NSW's South Coast, stretching through to the southernmost tip of our network at Bawley Point," an Endeavour Energy spokeswoman said.
The wooden poles are made of Australian hardwood, including spotted gum, grey gum, grey box and tallow wood.

The spokeswoman said they had a stockpile of 860 poles but have had to source more poles from other electricity distributors.
"Earlier this week Endeavour Energy initiated an industry stocktake of poles across the NSW and Queensland electricity industry so that we can share information to help us achieve our top priority of safely restoring power to customers, regardless of where damage is found," the spokeswoman said.
Where possible, the burned wooden poles have been replaced by metal ones, which are more resilient to fire - but there just isn't enough to go around.
"Our longstanding practice in bushfire areas is to replace burned wooden poles with concrete or steel poles," the spokeswoman said.
"Since we have exhausted certain sizes of concrete/steel poles, we are now replacing wooden with wooden to expedite prompt restoration for customers."
While most homes in Endeavour's coverage area on the South Coast and Southern Highlands have been re-connected to the network, there are a number being powered by generators.
They will be connected to the network in the coming days, the spokeswoman said.
