and we are not the preferred supplier of grid scale energy storage for Twiggy's mines


Andrew Forrest’s iron ore and green energy juggernaut Fortescue Metals says it has commissioned its first two big battery storage installations at its Pilbara iron ore mines, and begun construction on its first big solar farm as it accelerates its switch to green energy.
The two battery storage installation – totalling 42MW and 13MWh – have been installed at two different Fortescue mine sites – North Star and Solomon – and are part of the Pilbara Energy Connect project, which aims to power the miner’s Pilbara iron ore operations mostly with renewable energy.
The batteries – using Hitachi and Kokam technology – have been installed and commissioned by Hybrid Systems Australia, a subsidiary of Pacific Energy, and will use millisecond-response capabilities to provide greater protection against load spikes and dips and ensure overall network stability.
The batteries’ primary role is for grid stability and support, providing spinning reserve backup to any gas generation outages or sudden changes in the solar output. That explains the relatively short storage duration (just 20 minutes at full capacity).
