You can solve the power loss problem [in the old base] with a little re-wiring. It seems the spatial pylons are always on, and the removable cable segment only shuts down power to the Spatial IO port.
Look behind the Stirling Generator, change things so there is no connection between the pylons and energy cells. Dig out a small basement (this makes things easier), put a cable from one of the pylons to underneath the spatial IO. Then you can turn everything off with one cable, or a ME toggle bus + lever.
Note: You can run the glass cables next to each other without toughing, if you put some sort of Cover between them [Microblocks].
