ABB Australia has won an order worth approximately $30 million for a substation that will increase power supply and enable Rio Tinto to expand iron ore mining at Hope Downs mines in the Pilbara region.
The new Hope Downs-4 mine will receive power from the turnkey project that includes the design, supply, installation and commissioning of a new 220/33 kilovolt (kV) substation to be completed by the middle of 2012.
ABB will supply of power transformers, instrumentation transformers, disconnectors and a range of high- and medium-voltage air-insulated switchgear as well as provide civil and electrical works.
The company will supply and equip Substation automation systems compliant with the IEC 61850 global standard with the latest generation of protection and control products.
To reduce electric losses and improve network stability, the substation will also feature 11 kV reactors and capacitor banks.
“Reliability, efficiency and quality of power supply are critical to ensure productivity in mining operations, and this new substation will help to meet Rio Tinto's additional electricity needs and support the company's expansion plans,” said Axel Kuhr, country manager for ABB in Australia.
ABB has supplied 13 substation systems and installations since 2005 in the Pilbara region with the existing 220 kV substation constructed by ABB more than five years ago to supply reliable power to the Hope Downs-1 mine.
The two substations will power a staff village of more than 600 personnel as well as supply electricity supporting an annual iron ore production capacity of 15 million tons at the new Hope Downs-4 mine. They will also support mine dewatering, an open cut shovel and wet ore processing infrastructure.
