Government ownership of a re-booted State Electricity Commission would be enshrined into Victoria's constitution if the Labor government is returned to power.
Speaking at Yallourn in the state's east on Tuesday, Premier Daniel Andrews promised to safeguard the commission from privatisation.
"The last thing we want to do is build this up, make it better than it's ever been - for people, not profit - to then have a future Liberal government," he told reporters.
