Some residents at Kareela were still without power on Wednesday morning after the ferocious storm, which hit parts of Sydney on Tuesday afternoon.
Councillor Barry Collier, a Kareela resident, said an Ausgrid worker told him it was unlikely power would be reconnected on Wednesday.
Thousands of homes and businesses in Sutherland Shire and St George were left without power and some were damaged by a severe "hit and run" storm, which hit parts of Sydney on Tuesday afternoon.
Ausgrid said about 4600 properties at Oyster Bay, Kareela, Jannali, Sutherland, Sylvania, Kangaroo Point, Miranda, Engadine, Menai, Caringbah, Lilli Pilli, Port Hacking and Dolans Bay were affected.
Allawah, Carlton, Hurstville and surrounding suburbs were also left in the dark.
Sutherland Shire SES responded to more than 30 calls.
At Kareela, a tree next to the footpath was uprooted and fell across Ingrid Road.
Power poles and wires were damaged, a water pipe was broken and the road was blocked.
"It was lucky no one was killed," said Councillor Barry Collier, a Kareela resident.
The main damage was in the northern suburbs, where trees were uprooted, power lines brought down and cars smashed.
North shore train services were cancelled, resulting in huge queues for buses.
At 6am on Wednesday, 44,000 properties were still without power in the northern suburbs.
Power was gradually returned to most suburbs in the shire and St George during the evening and night.
However, some homes at Kareela were still without power on Wednesday morning.
