"Crews are working with Powercor to make areas safe for continued fire suppression and road reopenings,” she said.
"Several towns and outlying areas remain without power."
The spokeswoman said estimated losses from the fires were 18 houses, 42 sheds and significant stock losses.
"Impact assessment teams are working to asses property loses," she said.
"Many local roads remain closed. The VicRoads website has the most up-to-date information about road closures.
"We have had firefighters from across the state relieving in the fire zones," she said.
Victoria Police arson squad members travelled to the fire zones and were conducting investigations.
The Hawkesdale, Garvoc and Terang fires are suspected of being started by electrical assets.
The cause of the Camperdown fire is yet to be determined but is not believed to be suspicious.
Detective Sergeant Mark James, of Hamilton police, said the Hawkesdale fire was believed to have been started by a power pole.
Detective Sergeant Andrew Raven, of Warrnambool police, said initial investigations pointed towards electrical assets being the cause of the Garvoc and Terang fire.
He said there were no reports of anyone missing.
"There's no person unaccounted for at this stage. If there was I would have expected that to have filter through," he said.
"We are compiling a list of properties which were destroyed. We will search those areas and ensure everyone is account for," he said.
Buses were running between Warrnambool and Melbourne on Monday replacing rail services.
V/Line staff were inspecting the Melbourne-Warrnambool rail line on Monday after reports there had been damage caused by fire to the line.
