Electrifying the Pilbara
What changed and why
7 October 2026. First publication. All costs use one discount rate, an 8% real pre-tax weighted average cost of capital, for the trucks, the grid, the net present values and the per-tonne figures. Four context slides (Canada, Chile, BHP and Rio Tinto, published studies) are held back until their sources have been checked.
