Emergency crews are currently working to get power back up at approximately 2,500 homes and business across Sydney's south-west.
According to Ausgrid, affected areas include Bankstown, Padstow, Punchbowl and Condell Park.
Power went out just after 11.15am this morning.
Crews are looking to identify the fault and get the system back up and running as soon as possible.
The estimated time for restoration is 1.30pm.
This comes after an earlier power outage to Lidcombe, which has since been resolved.
