Coal-fired power stations at Hazelwood and Anglesea would be phased out from as soon as next year under a Greens plan the party is vowing to pursue if it wins the balance of power in Victoria.

Under the scheme, decommissioned power plants and mines would be replaced by solar farms and other renewable energy projects, which would create hundreds of jobs.

Victorian Greens leader Greg Barber will be joined by federal leader Christine Milne on Thursday to outline the plan to phase out dirty power plants across Australia, starting in Victoria.

Citing the Australian Energy Market Operator, the Greens say Victoria has more energy than it requires and can phase out some power stations without risking blackouts and price spikes while also delivering climate benefits without taxpayers' funds being spent.
