That's a 16.56 MW bucket excavator! But the conveyor draws 27 MW. Definitely needs its own substation infra. Quite amazing at that size that electric is the way to go.
I've spent some time in mining, electricity for heavy excavators has been a thing since the 1970s, even the 100 tonne trucks have had electric motor drives since then (albeit powered by onboard diesal engines that generate the power to banks that run the individual per wheel drive engines and regen charge from braking.
The next great leap forward is projects such as the "Infinity Train" that aim to recover electricity from the annual lowering of almost a billion tonne of iron ore per annum to sea level from an inland height of some 600m above MSL.
It was impressive driving by those behemoth digging machines when I travelled by train to Berlin in the 90's. Now two and a half decades later most of the East German lignite mines have been turned into lakes surrounded by nature. Definitely a change for the better :)
considering there's only one of them, i'd imagine getting replacement parts is just as hard as getting common parts out bush here heh. minus the reality tv stuff of course
