The power infrastructure investment for electrifying the iron ore industry alone could reach $30–45bn, requiring as much as 11GWh of additional electricity per metric ton of iron ore for a grand total of 20–30TWh – equivalent to 10–15% of Australia’s annual electricity consumption

However, electrifi cation could reduce energy costs by as much as 40–70% and reduce maintenance costs for mobile equipment by approximately 30%
