Powerlines Plus were engaged by ABB Australia to supply and construct the expansion of the South Hedland Substation to provide a substation upgrade solution for connecting the transmission grid to the new 150 megawatt (MW) combined cycle gas power station currently under construction in South Hedland, Western Australia.

TransAlta, the power station builder, operator and owner placed the order in the fourth quarter of 2014.

The upgraded substation enabled TransAlta’s new South Hedland Power Station (SHPS) to supply electricity to Fortescue Metals Group and Horizon Power, a state owned utility in the Pilbara. Once complete, the SHPS will be one of the most efficient in the region.

Currently the South Headland Temporary Generation plant installation, owned by Horizon Power, consists of a number of temporary open cycle gas turbine (OCGT) power generation units, associated equipment and 220 kV high voltage substation facilities.

The existing facilities are to be augmented and integrated into the new permanent power generation and power export facilities to meet the operating requirements of the new TransAlta power station.
