DENVER, 12 June 2007 — CH2M HILL and GE Energy (GE) today announced its consortium will be the engineer, procurement and construction (EPC) contractor for Australian-based Origin Energy’s new 630 megawatt Darling Downs Power Station to be located in Queensland, Australia.

CH2M HILL and GE will design and construct the US$660 million (AUD$780 million) project, which will operate from single-fuel plant firing coal seam methane gas and utilize an air-cooled condenser for the plant’s primary cooling system.

CH2M HILL will perform the engineering, design and procurement of the offshore "balance of plant" equipment for the project, integrating with the GE-supplied three Frame 9E gas turbine generators, a C7 steam turbine generator, and three heat recovery steam generators.

CH2M HILL will partner with Laing O’Rourke Australia for the site execution of the project works as well as supplying equipment, components, and materials through the company's Australian Industry Participation Plan.

"We are pleased that our consortium team of CH2M HILL and GE were selected for Origin Energy's new power station," said Don Zabilansky, president, power business group, CH2M HILL. "We look forward to executing this marquee project, along with both GE and our site execution partner Laing O'Rourke," Zabilansky said.

"The combined cycle gas turbines, together with the use of coal seam gas for fuel will ensure the plant has extremely low carbon dioxide emissions," said Grant King, Origin Energy's managing director. "The use of air cooling will put minimal demand on the State's precious water supply," King said.

Plant construction is expected to begin in August 2007, commissioning in the fourth quarter of 2009, and ramping up of full commercial operation in the first quarter of 2010.

CH2M HILL has been actively performing projects in Australia since the early 1980s. The company has four area offices in Brisbane, Sydney, Melbourne, and Perth, as well as in Auckland, New Zealand.
