Inside the power plant are multiple feral ghouls, and, depending on your level, you may also encounter multiple feral ghoul roamers, glowing ones and, with Broken Steel installed, feral ghoul reavers.
It can be found in the upper area of the derelict power plant right across from MDPL-13 power station, next to a terminal on a desk. Firsto! is a unique variant of the pneumatic Power Fist that is more durable and deals higher base damage than the standard model.
