Construction is underway on Fortescue’s 440 MW solar farm at Solomon Airport in the Pilbara, set to be Western Australia’s largest single-site solar installation and a key power source for the Solomon iron ore hub. The project will integrate with existing battery energy storage systems such as the North Star Junction BESS to displace a substantial share of gas and diesel generation on the mine’s microgrid. For mine planners and electrical engineers, this scale of behind-the-fence PV will drive new approaches to load management, contingency planning and grid stability.
The 440 MW Solomon Airport solar build slots into a broader decarbonisation push in Fortescue’s Pilbara iron ore operations, which our coverage shows also includes battery-electric locomotives and ultra-class battery-electric loaders and dozers commissioned since early 2026.
Locating Western Australia’s largest solar farm near the North Star Junction battery energy storage system suggests Fortescue is designing an integrated renewables–storage backbone that can directly support its heavy rail and mine power loads rather than relying on grid tie-ins.
Within our 1,097 Mining stories, Fortescue features frequently in ‘Projects’ and ‘Sustainability’ pieces, signalling that its Pilbara renewables build-out is now a core strategic lever for maintaining low C1 iron ore costs while managing future carbon and diesel price risk in Western Australia.

ICMM has released a Global Mining & Metals Greenhouse Gas Emissions Dataset and insights report showing that extraction of minerals critical for renewable energy technologies and sustainable development contributes a relatively small share of global GHG emissions. The dataset aggregates Scope 1 and 2 emissions from mining and metals operations worldwide and distinguishes them from downstream processing and end-use sectors such as power generation and transport. ICMM positions the tool to support more accurate value-chain accounting, scenario analysis and decarbonisation planning for commodities like copper, nickel, lithium and rare earths.
Epiroc has signed its first ground support partnership in Oceania and Indonesia with DYWIDAG Australia, giving it wider distribution for products such as rock bolts, mesh and dynamic ground support systems in hard‑rock underground mines. The agreement targets high-stress, deep mining environments in Australia and Indonesia, where squeezing ground, seismicity and corrosion demand integrated support packages rather than standalone consumables. For operators, the deal signals broader local availability, shorter lead times and potentially more standardised support designs across multi-mine portfolios in the region.
Construction has commenced on Fortescue’s 440 MW Solomon Airport solar farm in the Pilbara, set to be Western Australia’s largest solar development and supplying about one-third of the solar capacity the company says it needs to reach its Real Zero emissions target. The project will feed Fortescue’s nearby iron ore operations, reducing reliance on gas and diesel generation across the Solomon power network. For mine planners and electrical engineers, this scale of behind-the-fence renewables will drive changes in load management, network stability design and contingency planning for remote operations.
