Hi,
It was intended that the power consumption of assembly machine 4 would be slightly high.
Once you’ve got past Aquilo, energy isn’t really an issue anymore, so that shouldn’t be a problem. What’s more, the increase in speed between 1.25 and 2 is quite significant, so there needs to be a cost for it, otherwise it would be too easy.
By comparison, buildings like foundry, EM plant and cryo plant are between 1,5MW and 2,5MW.
So I think having at least 1MW isn't that much.
