It'd be nice, for me, if I could have this generate the system without including a substation. I'd rather use my own power distribution placements, than have this resolve the issue for me. thx.

the problem with that is you wouldn't be able to access the circuit network within the entities. Is it just the wire that bugs you? Or is it the supply area?

Ah. Supply area. I didn't see that limitation, though, so no problem that it isn't trivially solvable. :)

I can put a startup setting to remove the supply area but leave the substation in place. I don't know exactly when I'll get to it but that's a relatively easy addition.

Well, thank you. I appreciate that.

So in messing around with this idea a problem comes up, the invisible inserters don't have power. So the only 2 options I can think of would be to make them not require power to operate (seems kind of cheaty), or go through and make the sub station supply area only effect the machine footprint(decent amount of code work). Any thoughts or ideas?

Its is necessary to use exactly substation? If not, may you replace it with a wooden pole or a modified pole with a smaller supply area?

Unfortunately using a different entity won't make any difference as you can make a pole have the same size supply area as a sub station and vise versa.
