Inspections are currently underway at AGL’s Liddell Power Station (NSW) after a recent external boiler tube leak.
AGL is conducting inspections on all four boiler units at Liddell and, if required, will conduct repairs. However, this will result in outages over two months.
Currently, units one and four are out of service and undergoing repairs, while units two and three are operating safely at reduced capability.
Unit three was shut down for repairs in late March 2016 and unit two will be shut down for repairs when work has been completed on units one and four.
AGL said it the Australian Energy Market Operator (AEMO) will be kept informed about the availability of all Liddell units.
The financial impact of the outages is estimated at $15million to $20million net profit after tax all occurring in the current year FY16. The estimate reflects both the direct loss of generation revenue and estimated broader impacts on the electricity-trading portfolio.
There is no change to the previous guidance statement for FY16 Underlying Profit, which is expected to be in the upper half of the guidance range of $650million to $720million subject to normal trading conditions for the remainder of the year.
