On 31 October 2019, ownership of Stanwell's low and no emission power stations was transferred to CleanCo Queensland. This includes the gas-fired Swanbank E Power Station and the three Far North Queensland hydro facilities (Kareeya, Barron Gorge and Koombooloomba). Windy Hill Wind Farm in Queensland and Toora Wind Farm in Victoria were owned by Stanwell but were sold to Transfield Services in 2007. The company also subsequently sold Emu Downs Wind Farm in Western Australia.
