Top Energy chief executive Russell Shaw confirmed that the man died after climbing the pole and touching live high-voltage conductors.
"Our condolences and thoughts during this terrible time go to the family of the person who died," he said.
The company's first priority was to work with police and firefighters to make the scene safe. It would continue to help police and Energy Safety, a government safety regulator, with their enquiries.
Police were expected to hand the site back to Top Energy last night and replacement equipment was due to arrive today.
Mr Shaw said Top Energy would conduct its own internal investigation.
Fire Service volunteer support officer Colin Kitchen said the incident was " traumatic" for firefighters and bystanders.
The volunteers were trained to deal with distressing situations.
