Mod «Underground Power Conduits» for Rimworld (v1.0 - 1.4)

A small mod which simply lets you build power conduits underground. It uses the same amount of resources, as your pawns are essentially building the same thing, but the trench building process is over 10x more labor intensive compared to laying down surface cables.

It also includes underground waterproof conduits.

As with similar mods, subsurface conduits are spared from any beauty score, and are protected from stray projectiles (explosions will still get them, though).
