UGL and CH2M Hill have won a $550 million contract to build the combined cycle power plant for the Ichthys liquefied natural gas project in the Northern Territory.
As part of the agreement GE will engineer and supply gas turbines, steam turbines and heat recovery steam generators for the $32.63 billion project.
The CH2M Hill-UGL joint venture will design and supply the rest of the plant, as well as constructing the project.
UGL chief executive Richard Leupen said strong growth momentum in gas turbine generation facilities continued to be supported through private investment in the mining sector.
"For UGL, as part of the consortium with CH2M Hill and GE, this is a significant win and demonstrates our consistent ability to leverage our engineering capabilities, in this instance our power generation expertise, to deliver work on significant resources projects," Mr Leupen said.
The $US34 billion ($A32.63 billion) Ichthys gas project will pump gas from offshore Western Australia to Darwin for processing through an 885km undersea pipeline.
