About 77,000 homes and businesses remain disconnected from the electricity network as of 5.30am on Thursday, down from 125,000 on Wednesday evening and 530,000 at its peak.
Crews worked through the night to clear debris and repair powerlines to reconnect properties, following damage from storms, strong winds and lightning.
But given the extent of the damage, it could take days or more than a week to restore electricity to those impacted, the Australian Energy Market Operator has warned.
We're responding to one of the largest outages in our state's history. Our crews worked overnight to assess our network and respond to ~ 400 faults. Due to large volumes/complexity, we're still working on est restoration times. We're updating customers via website, SMS, Facebook. — AusNet Services (@AusNetServices) pic.twitter.com/KnXaTP2V8vFebruary 14, 2024
AusNet executive general manager Steven Neave said that as of early Thursday morning around 75,000 of its customers were still waiting for their power to be restored.
The main areas affected are Yarra Ranges, south Gippsland and the Bass Coast.
"We'll have 400 crews on the ground again today, we've been working through the night," Mr Neave told Nine's Today show on Thursday.
"It's really clearing that vegetation out of the way, getting safe access to all the streets and suburbs where this storm has gone through and progressively ... restoring supply as safely as we can."
However, some customers may not get their power back until next week.
"We are hoping to have somewhere around 30,000 or more back on today, and then the bulk of them back on by Saturday," Mr Neave said.
"Unfortunately, there could be some customers that are still off supply into next week, but we are hoping to have ... the vast majority back on by Saturday."
The disaster was one of the largest power outages in Victorian history and could take weeks to fully fix.
