GenusPlus Group is awarded a $55 million master construction contract from Rio Tinto to deliver an upgrade at the Millstream substation in the Pilbara. Multiple reports state the work involves a 220kV upgrade, which supports Rio Tinto’s wider energy infrastructure plans. The contract is described as part of preparations for additional renewable power expected to come online in the region. GenusPlus is positioned to perform the construction scope associated with the substation upgrade, with delivery tied to enabling grid capacity for incoming generation. The coverage is consistent that the project is specifically linked to Rio Tinto’s Millstream substation and that the contract value is $55 million. Both sources frame the award as an element of broader energy build-out activity, rather than a standalone project, with timing and scope focused on upgrading key transmission infrastructure ahead of further power generation additions.
