SUSTAINABILITY
In the red-dirt Pilbara of Western Australia, a place that could have been borrowed from Mad Max, more than a million solar panels are being bolted to the desert floor some 120 kilometres south of Port Hedland. They exist to feed one company’ s pits, trains and trucks, a power station the size of a small town built to serve holes in the ground.
This is Turner River, a 690MW solar farm being built by Fortescue, the Australian iron ore giant, and it tears up a bargain mining has kept since the first steam shovel.
Energy, the industry always assumed, was something you bought, hauled in and burned. Diesel moved the mountains; convoys of tankers crossed the outback to keep the engines fed; the fuel invoice was simply the price of the dirt. Fortescue is done with all that.
Now the planet’ s biggest miners have quit buying power to make it themselves, storing it in batteries, wiring it straight into the pits, the trains, the ports. The mine of the future is not plugged into the grid. It is the grid.
Fortescue calls its version the Pilbara Green Grid: solar and wind, batteries, electric trucks and 620 kilometres of its own transmission, wired straight to the pits and the port. The goal is energy autarky, a mine that makes every electron it burns.
“ While others are still debating whether decarbonisation is possible, Fortescue is getting on with building what’ s needed to do it,” says Dino Otranto, CEO of Fortescue Metals.“ Anyone watching global fuel markets can see exactly why electrification and renewable power matter more than ever.”
