Stanwell Corporation hopes to have repairs completed on Unit 1 at Tarong Power Station by the middle of next week.
The generating unit suffered a tube leak about 10 days ago and was taken offline last week to enable work to begin to fix the hole in the boiler.
Power Station Site Manager Dennis Franklin said having the unit offline – which is on top of the mothballing of Units 2 and 4 – would not affect Queensland electricity supplies because the market at the moment was still “well and truly over-supplied”.
The power generation unit at Tarong North, and Unit 3 at the original Tarong power station, are still supplying power to the grid.
“There’s no chance of blackouts or brownouts,” he said.
Mr Franklin said tube leaks were not unusual; in fact, this is the fourth at Tarong so far this year (other leaks have been at Tarong North, Unit 3 and Unit 1) however this one had occurred in a more difficult spot to repair which had necessitated taking the unit offline for a longer period.
He said specialist contractors and engineering consultants were completing the repairs.
