 This decision was primarily driven by increasing levels of wind and solar generation in the South Australian region of the National Electricity Market displacing fossil fuel generation, particularly higher cost gas-fired generation.AGL reviewed this decision and deferred the planned mothballing in June 2016, following the closure of Alinta's Northern and Playford B coal-fired power stations at Port Augusta

However, due to the state-wide power outage in September 2016, the system operator AEMO demanded that the Torrens Island power station to be brought back online to prevent another statewide power outage.AGL announced on 7 June 2017 that it intended to permanently mothball two of the turbines in the 50-year-old Torrens A power station from 1 July 2019, after building a new 210MW power station containing twelve gas reciprocating engines to be known as Barker Inlet Power Station adjacent to the Torrens Island site.
