AGL is sending a spare 255-tonne generator from Loy Yang A Power Station to Germany to be refurbished by Siemens, the original manufacturer, to ensure it can be used as a replacement generator at short notice in the future should the need arise.
Loy Yang A uses four generators at its 2,210MW plant in LaTrobe Valley and the generator being sent for refurbishment was installed in Unit 1 until late last year when it suffered an electrical fault. A replacement generator was installed on Unit 1 in 2017 in time for this summer peak demand.
Currently all four units at Loy Yang A are in service and this activity will have no impact on generation from Loy Yang A.
Getting the generator refurbished at the Siemens’ specialist workshop in Germany with the right equipment and expertise is both costly and logistically challenging, but we believe it’s the right investment to make to ensure longer-term reliability.
Following refurbishment, the generator will be back at Loy Yang by November 2018 where it will be installed into Unit 4 during its planned 40-day outage scheduled ahead of next Summer.
Loy Yang A also has an additional spare generator. Having a spare generator available can speed up the time it takes to return plant to full operation in the event of an unplanned fault.
