In October 2023, the power station's owner, AGL, was fined 6 million AUD for "failing to deliver stand-by power when it was paid to do so," including power purchased from the Bayswater power station from 2018 to 2020.[2]
In February 2018 AGL announced that it would be investing A$200 million on a maintenance project to upgrade Bayswater, including installation of new turbines that would increase the plant's overall capacity by 100 MW. The installation of the new turbines would begin in February 2019.
In March of 2021, AGL announced that it had commenced a A$152 million maintenance and upgrade program at Bayswater, expected to be completed in June 2021. The works include a turbine upgrade, replacing the unit’s distributed control system, as well as a cooling tower repack and maintenance works on boiler, gas air heater and electrical plants.[8] In March 2022 Unit 4 was taken offline as part of upgrading its capacity from 660 MW to 685 MW.[9]
As of July 2021 the plant was scheduled to continue operating until 2035.[10] However in August 2021 one of the biggest users of power from the plant, the Tomago Aluminum smelter, announced that it would switch to renewable power by 2029, which could force Bayswater to close that year.[11
In July 2021 it was reported that AGL paid an A$1.1 million fine for the April 2021 discharge of fly ash into Bayswater Creek.[10]
In February 2023, AGL was fined A$15,000 ($10,471 USD) over the discharge of saline water into the nearby Bayswater Creek.
