Liddell Unit 2 Unplanned Outage
AGL advises that following investigation of recently reported turbine vibration issues, Unit 2 at Liddell power station will remain out of service for repairs until early 2018.
The repair duration is primarily due to the time needed to procure specialist spares for a power station of Liddell’s age.
Unit 1 at Liddell is also out of service for planned maintenance, and is expected to return mid November 2017.
Units 3 and 4 at Liddell are in service, as are all four units at Bayswater power station.
No impact on customers or security of electricity supply is expected.
AGL will continue to keep the Australian Energy Market Operator (AEMO) informed.
Since acquiring Liddell power station from the NSW Government in 2014, AGL has invested $123 million in plant reliability works.
This has resulted in substantially improved plant performance. Liddell Unit 3 for example, is currently on a record run of over 230 consecutive days in service.
AGL will invest an additional $159 million in reliability improvement maintenance to ensure the plant operates effectively to 2022.
The four Liddell power station generation units were commissioned between 1971 and 1973. Liddell currently has 1680 MW of effective capacity. It supplies approximately 8,000 GWh of electricity a year, which is enough to power more than 1 million homes.
