I think it would be really cool if players could create their own power grid in a fully-player-made base/home or modify existing power grids.
I'm essentially looking for a way to be able to build my own house from scratch, and be able to make my own ceiling lights, light switches on the walls, and have a working power grid so I can throw a fridge or two down in various places.
or even just be able to run a line of "extension cords" from a generator or powered building to some lamp posts or other outdoor lights so I can light up my driveway with out having to burn through a metric ton of batteries.
