Piper Alderman advises on largest transmission infrastructure project in decades to power South Australia’s mining industry
Piper Alderman advised ElectraNet on its contract with CIMIC’s UGL to design, construct and commission high voltage substations and 300km of transmission lines that will connect the OZ Minerals Prominent Hill Mine to the South Australian electricity grid. Spanning 300km, this $270m project is one of the largest transmission infrastructure projects in the last 30 years.
We were pleased to work with the ElectraNet team to successfully deliver this significant high-voltage transmission line and electricity substation which provides transmission services for OZ Minerals’ Prominent Hill and Carrapateena mine sites.
Piper Alderman advised ElectraNet on its Design and Construct contract with CIMIC’s UGL to design, construct and commission high voltage substations and transmission lines that connect OZ Minerals to the South Australian electricity grid. As part of the contract, UGL designed, constructed and commissioned switching station infrastructure and approximately 300kms of high voltage transmission lines.
Additionally, Piper Alderman advised ElectraNet on its build, own, operate and maintain (BOOM) and transmission connection arrangements with OZ Minerals. OZ Minerals entered into arrangements with ElectraNet to construct the new 300km high voltage transmission line and associated infrastructure to support its Prominent Hill operations in South Australia’s upper north region. The transmission line replaced the existing BHP facility and began operation in 2020.
ElectraNet’s Chief Executive, Steve Masters, said the project was the largest ElectraNet has ever undertaken to date and the new OZ Minerals connection will play a critical role in powering the mines’ operations.
