The current power wiring system feels clunky. I'd suggest giving bases a wireless power grid that each generator you build feeds capacity into. No need to wire any gear up; just turn it on, and it will use any available capacity.

Also, I'd like to see power "repeaters", so you can extend the range of the power grid. And while we're at it, allow the player to power the entire grid on and off from a single interface.

Note that this would allow hyperloop-like transport, since you could build a track with power nodes for vehicles without their own power sources.
