Endeavour Energy crews will work overnight on Monday and into Tuesday to restore power to hundreds of homes in Shoalhaven and Southern Highlands as flood waters begin to fall.
The energy provider says 270 electrical hazards still need to be repaired following the weekend deluge. That includes fallen trees and power lines.
And Endeavour Energy spokesperson said around 400 customers in the Southern Highlands, Shoalhaven and Hawkesbury will be without power overnight due to flooding preventing crews from accessing parts of the network to make repairs.
