An industrial dispute lasting more than a year of back-and-forth is over, with workers at the Yallourn power station in the Latrobe Valley accepting a final wage agreement.

Failed negotiations saw a range of industrial actions since the stoush started in 2012, but Yallourn operators Energy Australia now saying workers overwhelmingly voted in favour of the latest wage and conditions offering.

The deal will see workers receive a 22.5 per cent pay increase and a more robust dispute resolution clause.

The protracted dispute came to a head when seventy-five Construction, Forestry, Mining and Energy Union workers were locked out of the site.

The lock-out led to a 100 day stand-off, which ended with an in-principle agreement last months.

The final enterprise agreement is now being sent by Energy Australia to the Fair Work Commission, so that it can be checked over and finalised.
