Id like a large scale electrical tower for power transport, Like the huge ass metal towers you'll see near highways sometimes. Just something big looking with a huge distance to transport power with the cables high off the ground as to not get in the way of your factories.
Id give it the ability to connect to other Electrical towers and have it require a transformer station to pull power from it. Have a higher cable cost than normal power poles have but still cheaper than placing 600 poles. Make it a mid to late game building (Tier 5-6)
I want one partially for that industrial Aesthetic but also as a useful item when you've got a power plant thats far off.
Cost for the tower could be;
50 Limestone
150 Iron Rods
25 Caterium Wire
20 Heavy Modular Frames
and have the Transformer Station be
100 Caterium
500 Copper
20 Computers/AI Limiters
15 Encased Steel
Any suggestions welcome
