MORE THAN 100 Aurora and Transend staff will be out of work at the state-owned energy companies at the end of today.
The transmission and distribution enterprises will cease trading as separate entities at the close-of-business before merging into a single company.
The new poles and wires business, TasNetworks, will begin operating tomorrow.
Aurora's retail arm is not included in the restructure.
It will continue to do business as a stand-alone company, competing with prospective private retailers from tomorrow.
A Transend spokeswoman yesterday confirmed the total number of redundancies at the company stood at 32 - unchanged from a figure released earlier this month.
At least 77 jobs will be lost from Aurora, with the final number expected to be available later today.
The total number could be slightly higher, with a number of staff at the company taking part in negotiations over the past few weeks in the hope of securing short-term, contract work at TasNetworks.
The merger is expected to save about $8 million, and forms part of the state government's energy market reforms.
Redundancy costs at each business will be included in their annual reports.
