POWERCOR has confirmed the cause of more than 1200 residents losing power was due to a tree falling onto a power pole in Holmes Road, North Bendigo.
The incident, at about 8.30am, is suspected to have caused a power surge and affected houses in California Gully, Long Gully, Maiden Gully and North and West Bendigo.
A Powercor spokesman said most customers were back on line with about 400 people still waiting for their power to be restored.
Bendigo resident Stephen Stingel sent the Bendigo Advertiser a photo of the fallen tree.
He said he heard two loud bangs as the tree crashed down.

"It scared the crap out of me," he said.
"I live just near where it happened and I spoke to someone who said apparently there was a bit of a fire ball."
