A blaze that broke out in a electrical storage shed at the Port of Esperance in the early hours of December 3, has caused an estimated $2 million in damage.
The structure fire was reported to the Department of Fire and Emergency Services just after 1am.
Firefighters from the Esperance Volunteer Fire and Rescue Service and the Pink Lake Bushfire Brigade responded to the fire which was contained to one building.

"The blaze escalated and has resulted in the destruction of the shed.
"No personnel were injured as a result of the fire. There is currently no impact to port operations."
