Olney Powerworks

 is a location added to Fallout 3 in the Broken Steel add-on.

It is an old power plant in the sewers of Old Olney, owned before the Great War by PPE, which might have been a branch of Poseidon Energy. It is guarded by Sentry Bots where you have to go in order to find a Tesla Coil for the Tesla Cannon.

Notable loot

 * 3x12 Alien Power Cells can be found on the stove and table with the glowing electric globe 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). The hallway can be noted by the many servers along the walls and the two Mark V 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. Look above each of these to find two ammo boxes on shelves, they contain the Alien Power Cells (there is considerably more alien power cells (around 45) with the Scrounger Perk and is recommended to reap the largest amount of this rare ammo).
 * Nuka Cola Quantum behind an average locked cell door, along with a Chinese Assault Rifle and some ammo.
