Hydro Tasmania will shed 50 full-time-equivalent roles through an organisational restructure.
The state-owned company on Wednesday said the job cuts would occur over a 12-month period.
"Hydro Tasmania employees have been engaged in a business transformation process over the last six months to organise around delivery of core services and future opportunities, while flattening the structure to empower our people," it said in a statement.

"The proposed changes will create a number of new roles designed to meet future needs and will also see a number of current roles no longer required."
The company said training and development would be provided to displaced employees to help them transition into new roles and roles that become available through natural attrition.
"In the case that an impacted employee is not successful in securing a suitable alternative position, redundancy provisions will be available consistent with relevant awards, enterprise agreements and employment contracts," it said.
The company said the structural changes would be supported by technology investment and increased automation.
Hydro Tasmania chief executive Evangelista Albertini said the business needed to adapt to market conditions.
"As the electricity industry undergoes unprecedented disruption, we must adapt by becoming more agile and leaning into the opportunities of the future market," he said.
Hydro Tasmania says the business restructure will not impact the state's energy security or energy prices paid by Tasmanians.
