 Concept level proposals have been discussed for the replacement of the plant with either a gas-fired, a concentrated solar thermal plant or a nuclear power plant.On 11 June 2015, Alinta Energy announced its intent to permanently close the power station by March 2018, along with the related Playford B Power Station, and the Leigh Creek coal mine that supplies them both with fuel.This was updated on 30 July 2015 to bring the closure dates of all three facilities forward by 12 months, with closure to occur between March 2016 and March 2017.
