ALMOST 170 jobs will be scrapped from the total workforce when Transend and Aurora Energy merge in July.
TasNetworks said yesterday that duplicated executive, management and support services roles would be targeted in the restructure.
TasNetworks spokeswoman Justine McDermott said a pool of 275 employees with duplicated skills would compete for 211 vacancies in the new structure, accounting for 64 of the job losses.
Many candidates held roles in finance, information technology and human resources departments in either company.
Ms McDermott said the restructure would create a lean, efficient business.
"We have looked closely at each business to identify where we can reduce costs and deliver reform objectives," she said.
"These are essentially similar and complementary businesses ... who are responsible for building and maintaining the networks that bring electricity to our households and businesses.
"The merger shines a light on business overheads, particularly where there may be duplication of management and other business support services."
Applications from permanent staff would be given top priority, followed by contractors. Remaining vacancies would be opened to the public.
The number of Aurora Energy and Transend employees who received redundancies would not be known until the recruitment process concluded in mid-June.
The Communications, Electrical and Plumbing Union said it was more concerned about the restructuring process than the resulting job losses.
"We don't believe it's been a particularly transparent process," state secretary Trevor Gauld said yesterday.
Mr Gauld said the CEPU was relieved all frontline staff would be transferred.
"The frontline is already significantly understaffed," he said. "Any further reduction would have resulted in safety issues and a reduction in network reliability, meaning more power outages for longer periods of time."
TasNetworks said yesterday that more than 770 Aurora Energy and Transend employees would be transferred to the single distribution and transmission business.
