In preparing to deliver priority grid projects, Australia’s largest TSO Transgrid has finalised an AU$100 million ($64.7 million) contract with ZTT Australia to supply 17,500km of high voltage conductors – enough to stretch from Sydney to Dublin, claims the operator.

The high voltage conductors contract is part of the Powering Tomorrow Together programme run by Transgrid, bundling procurement for major projects HumeLink, VNI West and EnergyConnect.

The programme will enable Transgrid to purchase materials, such as substation equipment, earlier and at a lower cost, enabling limited resources to be used across multiple projects.

The orders are also supported by AU$385 million ($249 million) Australian Government underwriting as part of the Rewiring the Nation program.

Commenting on the announcement in a release was Transgrid CEO Brett Redman: “We continue to build our global supply chain to secure the specialised kit needed to build the future clean energy grid and ensure competitive and efficient delivery of the Federal Government’s energy plans.

“We are also finalising a separate contract with another Australian company to supply other locally-produced conductor elements.”

Dean Farrar, ZTT Australia’s general manager, said the conductors will be manufactured in equipment manufacturer ZTT Group’s Hekou manufacturing campus and will be delivered to Australia in 2024 and 2025.

“We are honoured to be partnering with Transgrid for their current and future major projects. This contract builds on our ongoing commitment to support the Australian energy and telecommunications markets, now and into the future,” stated Farrar.

This year Transgrid also secured 15 shunt reactors and 25 single-phase transformers worth approximately AU$150 million ($97 million), with arrival planned for late 2024.

According to Transgrid, more than 2,500km of new transmission lines are needed to ensure access to renewable generators and interconnection between regions required to drive down wholesale energy costs.

Over the next decade, Transgrid plans to invest AU$14 billion ($9.4 billion) to build new transmission infrastructure including the AU$7 billion ($4.7 billion), 1,600km Southern Superhighway made up of three major critical transmission projects – EnergyConnect, HumeLink and VNI West.

Transgrid’s Powering Tomorrow Together Program is bundling procurement for these three projects to secure needed equipment and materials.
