Mineral Resources Limited (MinRes) has successfully commissioned a hybrid gas-solar power station at its Ken’s Bore mine site, part of the larger Onslow iron ore project in Western Australia, the company announced this week.
The newly constructed 26-megawatt power station is now fully operational, delivering power to essential mining infrastructure including crushers, reclaimers, and loaders. The facility is supported by a 16-kilometer underground high-pressure pipeline, linking the site to the Goldfields Gas Pipeline for continuous gas supply.
Hybrid Energy System: Solar + Battery Boost Efficiency
The hybrid system includes a 3.8 MW solar array, consisting of 6,600 photovoltaic panels with single-axis tracking to optimize solar capture. It is further supported by a 3.3 MW battery energy storage system (BESS) designed to deliver immediate power output during sudden drops in solar generation, such as during cloud cover.
Environmental Gains: Cutting Diesel and Emissions
By replacing traditional diesel power generation, MinRes expects the hybrid system to eliminate the use of 67 million liters of diesel annually, resulting in an estimated carbon emissions reduction of 47,000 metric tons per year.
The project highlights MinRes’ commitment to integrating renewable and low-emission energy solutions in its operations, aligning with Australia’s broader push toward sustainable mining practices.
