MDPL-13 Power Station

The Power Plant is infested with Ghouls and Radiation and should be avoided at all costs.

Of note, inside there is a single Glowing One (high radiation from this particular creature, and is tougher than other Ghouls), the Fisto! in the upper level office, a Nuka-Cola Quantum in the Sub-Power Station across the way, and a couple terminals that can be hacked (if you have the right skill).

The radiation point seems to be one particular silo tower inside the main building. Believe it to be the center silo, of the three.

Opposite the powerplant, there is a subplant building which contains a workbench, on the workbench you will find the schematics for the Railway Rifle
