Power has been restored in around 1,000 homes on Sydney's lower north shore after a major blackout this morning.
The blackout has affected several suburbs including North Sydney, Cammeray, St Leonards, Artarmon and Crows Nest since four o'clock this morning.
Traffic lights are out and the fire brigade responded to a resident trapped in a lift at McMahon’s Point.
Some office buildings are also affected with electric doors unable to be opened.
Energy Australia says one of its major power lines which supplies TWO sub stations at North Sydney and Gore Hill is down.
Kylie Yates from Energy Australia has told 2GB’s Alan Jones they're slowly re-connecting affected homes and businesses.
“People who’ve got their power back are people who live in Kirribilli, Waverton, Milson’s Point, Wollstonecraft, and parts of North Sydney.
“We’ve also restored power to Royal North Shore hospital – our engineers were able to re-route the power supply from other parts of our network.”
