Energy costs avoided (diesel, gas and bought-in power) less the grid’s and chargers’ running costs give an operating saving of A$1,130m a year. Deducting the capital charge on the grid, chargers and in-mine lines (A$841m a year at an 8% real pre-tax WACC) leaves A$290m.
This excludes the extra cost of electric trucks and equipment, which the project IRR includes. Diesel is valued at A$2.50/L delivered less the 53.7 c/L fuel tax credit, A$1.96/L. The A$150/MWh price for bought-in power is an unverified ITK assumption.
