Hunter MP Dan Repacholi is slamming Origin Energy for their "lowball" contract offer to Myuna Colliery.
The coal mine has been supplying exclusively to Eraring Power Station for more than 40 years.
But, a lapse in contract will likely see the facility shut its doors in March.
Origin Energy, the owner of Eraring Power Station, proposed a new 12 month extension of the mines operations, maintaining their current agreements.
However, Myuna owner Centennial Coal refused the deal, stating it was not commercially viable as the mine is already running at a loss.
The contract also provided little to no certainty to the mine's more than 300 employees, according to the Mining and Energy Union.
Hunter MP Dan Repacholi has since voiced his support of Centennial Coal and the union's decision.
"Origin's offer... was disgraceful," he said.
"It was a spin, not a solution.
"A short-term, take-it-or-leave-it proposal that provides no certainty for workers, their families or the local community is not good enough."
It comes after Origin announced operations at Eraring would continue until 2029, instead of it's initial closing date in 2027.
Mr Repacholi said it's not viable to have the power station running without the mine.
"Myuna was built to supply Eraring, there is no alternative market," he explained.
"If Origin walks away, this mine closes and that is a deliberate commercial choice, not an unavoidable part of the energy transition.
"The Hunter deserves better than corporate spin."
