Not sure if this was mentioned yet, but would be great if you had a new item in utility called "Generator Splice Box" or something like that where.
I have 2 generators set up at the north outer wall near the road, say I want to run the power cables parallel or at some point they will meet up but the splice box or splitter will actually keep the generators seperated so I can run lines around areas that would take an ungodly amount of time and money to A: dismantle move the generator II to another location. B: To drop lines that will practicly just circumvent the entire prison to get to where it needs.
Or instead of Split box, a new slightly more expensive cable called "Dual Heavy Cable" or even another version with it also called "Triple Power Line", first being 2 generators run on one cable but are split where going north on the cable sends power from the norht generator and sending the cable south sends the south generators power that way. In essence you would run one major long Dual or Triple power cable, than connect the single power lines to split them off.
Or just make it so we can have the option to bury another powerline under the current one.. not really realistic when I got 4 generators and there practically zig zagging across the entire prison to power sections, since all my generators are out front by the road along with a water pump
