The Greens have disendorsed one of their candidates for the Upper House seat of Eastern Region, three days before the Victorian election.

Cheryl Wragg, from the Latrobe Valley, was disendorsed last night in a row with Greens MP Greg Barber, over the proposed closure of the Hazelwood Power Station.

Ms Wragg will continue to appear on the Greens list on the ballot paper but says she will be running as an Independent.

She says Mr Barber's proposal to close down the Hazelwood Power Station in four years will not work.

"Mr Barber's plan proposes to replace the 1,600 megawatt base-load generation of Hazelwood with 1,200 megawatts of photovoltaics," she said.

"It just won't work. It's technically incompetent. Mr Barber doesn't seem to understand that base-load power needs to be there 24 hours a day."

Mr Barber says Greens candidates need to follow their party's policies.

He says the policy to shut down Hazelwood relies on renewable energy and on Victorians reducing their power use.

"There's no doubt it's challenging but we'll need a lot of renewables, much of which is on the drawing board, but most importantly deep cuts to energy use through an energy efficiency program across the state," he said.
