Olney Powerworks

Olney Powerworks is a location added to Fallout 3 in the Broken Steel add-on. The player is sent here in order to find a Tesla coil during the Shock Value quest.

Layout
It is an old power plant in the Old Olney sewers. It was owned before the Great War by PPE, which might have been a branch of Poseidon Energy.

Notable loot

 * 3x12 alien power cells. One can be found on each of the following: the stove, the table next to the stove and the table with the glowing plasma ball in the room at the bottom of the pit where the Tesla Coil is found.
 * 2x9 alien power cells can be found in the room past the Tesla coil (upstairs). (In an ammo box behind the right Mark IV turret.)
 * The hallway can be noted by the many servers along the walls and the two mark VI turrets at the end. At the very end of this hall, on both the left and right of the turrets, there are tiny alien spaceship playground models with arrows on the side of their stands pointing upward. Look above each of these to find two ammunition boxes on shelves, they contain the alien power cells. There are considerably more alien power cells (around 45) with the Scrounger perk, so having this perk is recommended to reap the largest amount of this rare ammunition.

Appearances
Olney Powerworks appears only in the Fallout 3 add-on Broken Steel.
