The facility's entrance opens to a small supervisory balcony and leads to a descending staircase. The turbines are partially flooded, obstructing part of the broken catwalk leading to the control room. A staircase on the northern side of the exterior leads up to the roof.
An issue of Tumblers Today is in the control room inside the building.
To the northwest of the turbide, up along the ridgeline, is a military checkpoint with a partial set of leveled power armor.
Poseidon Energy turbine No.18-F appears only in Fallout 4.
↑Fallout 4 Vault Dweller's Survival Guide Collector's Edition p.291: "[2.28] POSEIDON ENERGY TURBINE #18-F This is a small nuclear turbine used to the supply energy to much of the Commonwealth. The turbine is inactive. You find a quest item here if the quest is active. Clear the interior of disgusting mutant insects. Use the exterior roof as a defensive position if necessary."
