GE Power Down Under 2.0

Cape Lambert will use GE gas turbines for combined-cycle project; driving expansion of Western Australia mining operations

Posted on July 10, 2013

Mining company Rio Tinto installed GE’s LM6000-PF Sprint aeroderivative gas turbine with dual-fuel dry low emissions (DLE) technology for a new on-site power plant at its West Angelas iron ore mine in the remote Pilbara region of Western Australia.

Rio Tinto said it is implementing Australia’s largest-ever, integrated mining project to expand the capacity of its Pilbara operations by 50% from the current 237 million T/yr. to 360 million T/yr. in 2015.

GE said the same technology has also been selected for a new combined-cycle power station that will improve off-grid power generation at Cape Lambert, a seaport used for exporting iron ore from the company’s Pilbara mines.

The Cape Lambert power project marks the first time GE’s LM6000-PF will be used for a combined-cycle power application in Australia. For the project, GE is supplying an integrated, 130 MW combined-cycle power island package featuring two GE LM6000-PF gas turbines, two once-through steam generators, a GE Oil & Gas steam turbine and balance of plant equipment. GE will supply the power island to Forge Group Power, which has the engineering, procurement and construction contract for the complete power station.

GE said the LM6000 can deliver more than 40 MW of power at more than 40% efficiency while maintaining 25 ppm NOx levels when running on gas fuel, and 85 ppm when running on diesel fuel. The company said its dual-fuel DLE technology minimizes NOx emissions without needing water injection, which is a significant benefit for customers with limited water availability, a common issue in Australia.

GE is scheduled to deliver its gas turbines to Cape Lambert in the third quarter of this year, and the plant is expected to be operational by the first quarter of 2015.
