Hmm, I don't like it
Why not just place the factory outside of the power network on nauvis?
This change only benefits
1. people who want to build everything inside a single factory building
AND
2. they need separated electric networks
It's just way too small a usecase.
Besides, I can also imagine the experience where someone presses "R" key on the power pole on mistake, then thinks "ahh mod is bugged, cant transfer power"
