The Greens are pushing for a new public authority to take responsibility for Australia's beleaguered electricity system out of politicians' hands.

It follows several organisations, including energy company Origin, the Australian Council of Trade Unions and ClimateWorks, calling for an independent body, similar to the Reserve Bank, to manage what has been described as an energy crisis.

Focus on the future of the electricity system has heightened in the lead-up to the closure this week of Hazelwood, Australia's oldest and most emissions-intensive power plant, which when fully operational had the capacity to deliver about a quarter of Victoria's electricity.

The Greens will introduce legislation in the Senate to create what it calls Renew Australia, which it says can short-circuit a stand-off between the federal and state governments by taking responsibility for the transition to a clean electricity supply.
