AT LEAST 119 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.
An Aurora spokesman has confirmed at least 87 jobs will be shed from the company.
The number of Aurora job losses has climbed from 77 redundancies announced earlier this month.
The spokesman said the total number of jobs slashed from the company could be higher.
A small number of existing Aurora staff are still in negotiations in the hope of securing short-term, contract work at TasNetworks.
A Transend spokeswoman yesterday confirmed the total number of redundancies at the company stood at 32 - unchanged from a figure released earlier this month.
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.
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.
