ORIGIN Energy’s $650 million power station at Mortlake is yet to start adding electricity into the interstate grid for peak summer demand.
Final testing and commissioning of the gas turbines is still continuing despite the company indicating a few months ago it would be in full production by Christmas.
Origin began construction in March 2009 and at its peak about 370 people were employed at the site.
The 550-megawatt station is linked to the high-voltake Moorabool to Heywood transmission line and fed via an 83-kilometre underground gas pipeline from Port Campbell.
Completion was delayed by bad weather and technical problems.
It was initially scheduled for completion by late 2010, then delayed to the first half of this year. Origin is unable provide a firm completion date.
