ABB power conversion at Fortescue’s North Star: grid‑stability lessons for mine power
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Fortescue is installing an ABB power conversion system at its North Star Junction hub in the Pilbara to stabilise its emerging high‑voltage power network for large‑scale iron ore operations. The PCS will manage bidirectional power flows between grid, renewables and storage, providing fast frequency and voltage support to maintain quality supply for heavy mining loads and long overland conveyors. For engineers, the project signals growing demand for grid‑scale PCS integration in remote mines transitioning away from diesel generation.
Technical Brief
- ABB’s PCS is being deployed at Fortescue’s North Star Junction hub in the Pilbara network.
Our Take
Fortescue’s Pilbara iron ore operations have just delivered record FY26 shipments of 201.3 Mt in our coverage, so any ABB power conversion upgrade at the North Star Junction hub is likely being sized for high utilisation and incremental throughput rather than early-stage ramp-up risk.
ABB’s involvement at a Western Australia iron ore hub dovetails with Fortescue Zero’s push into the ABB FIA Formula E World Championship, suggesting Fortescue is cultivating ABB’s electrification and power electronics expertise across both its Pilbara mining systems and its branded technology ventures.
