I think a large steel foundry uses approximately 1/10 of the power of this facility.

Arc furnace foundry : 500 kw/tonne

Production : 150 t/hr

500*150 = 75 MW/h

I'm not 100% but I think you may have confused watts and watt hours somewhere in there. Wouldn't it be X kWh/ton?

		Yeah, I think you're right. Maff still maffs though. Units work out to MWh/h.. which makes sense to me
