Gas-fired power station begins dispatch

The first units of Origin Energy’s Mortlake power station dispatched into the Victorian electricity market in early January.

Mortlake power station is a 550MW gas-fired power station located near Mortlake in south-western Victoria. The power station has two gas turbines and will help to meet the growing demand for peak electricity in eastern Australia.

Completion of Mortlake power station’s second unit has been delayed so an inspection can be conducted of the generator following a switchyard fault that occurred during the final stages of the unit’s commissioning. This inspection will be conducted during the March 2012 quarter.

The project involved construction of an 83km underground natural gas transmission pipeline. The power station will be powered by natural gas sourced from Origin’s portfolio of gas supply arrangements in the Otway area, with direct access to gas from the Otway gas plant and gas storage at Iona.

Designed to be converted into a highly efficient combined-cycle plant, Origin has the option to expand its capacity in the future.
