Firstly - awesome! This should have been in the basic game!

I think the additional "powerpole" should have something more than just an update over the substation.

Additional features may be:
1a) Small radar
1b) One robot charge
2a) Lightning coverage
2b) Self heating
3) Player/spidertrone battery charge

Can be configurable (on-off) in mod settings.

4a) One beacon slot?
4b) Built-in an efficiency module with a small efficiency effect.
5) Extended wire reach - to make it possible to place it further than an electrical reach.
