The Power Substation extends your power network. It does not generate power of its own it draws from a Geothermal Power Generator (or another source) and re-broadcasts it, letting you reach parts of your park the generator cannot.

How it works

1. Place the substation within range of an existing power source
2. It requests power from that source and, while the source is running, becomes a source itself
3. Anything within 25 blocks of the substation is now powered

Because a substation only relays while its own source is powering, cutting the generator cuts everything downstream of it.

Range planning

Chain substations to cover long perimeter fences, keeping each one inside the previous one's radius.
