Powering Up Poseidon

Event: Powering Up Poseidon is an event quest in Fallout 76.

Overview
The player characters have the opportunity to repair the Poseidon Energy plant, requiring basic repairs to the reactor, generator, and cooling system. Doing so will restore power to a part of the region, activating power boxes at the plant (supplying 400 units of power to C.A.M.P.s and settlements) and at substations (100 per box). Otherwise, the boxes supply only 10 power.

The plant is located to the east of the Nuka-Cola plant and just north of the northern edge of Charleston. There is a railroad station nearby to the east with a vendor bot and other vending machines. The cooling towers are visible while traveling south from Flatwoods.

Quick
One needs a level 3 hacking level to get into the reactor. If one chooses to go through the cooling towers, the pipes emitting smoke must be fixed, along with the control panels. No materials are required to do so. Progressing to the generator room and reactor and fixing the consoles will result in the ability to power the reactor from the main control room, which concludes the quest.

Detailed
The player character needs at least the Level 1 Hacker perk to get past the reactor security doors. If they do not have this, they can still get in via the security control room by lifting the reactor and plant lockdowns.

The event has a timer of one hour. Once the event is triggered, proceed northeast into cooling tower 1 through a ground-level opening on the north side. There one will find a number of low-level Scorched, usually armed with pipe weapons or melee weapons along with turrets. After killing them, look for the pipes that are emitting steam and repair them along with the control panel on the catwalk, repeating the process for each tower.

Once complete, one will receive the message "Cooling system functionality is restored." Progress to the generator room, fighting past any remaining Scorched, and fix the control panels on each of the generator banks on each side of the room on the second level, and in the middle at the bottom. One will receive the message "Generator Functionality Restored."

The player character can now gain access to the reactor via an entrance to the southwest. Heading up the stairs, one can hack the terminal or backtrack through the security room, following the signs.

Upon entering a locker room, one can find damaged hazmat suits which can be used to negate the radiation of the reactor area. After making the required repairs in the reactor room, one will see the message "Reactor functionality restored." Optionally, at this point, one may lift the lockdowns at the security terminal.

Exiting the reactor room, progress upstairs to the main reactor control room and select the "Restart Reactor" option on the functional terminal, which concludes the quest.

Navigation
The plant is large and - due to numerous sections, tunnels, catwalks and horizontal layers - very hard to navigate. Luckily, for this quest it is only necessary to visit a small area. Once inside (coming from the cooling towers), the two walkways meet at a "Y" shaped intersection, where it is possible to drop into a pipe and arrive at the generator area. If the player stays in the corridor instead and continues SW, they pass radioactive barrels and arrive at a ramp going down. On the opposite wall there are two very large pipes.

This is the central point of reference, all quest areas are accessible from here. Right next to the ramp, to the NW, the spiral staircase (marked REACTOR/CONTROL ROOM) leads up to the control room and further up to the emergency entrance/exit to the reactor. From the control room, immediately left of the entrance, there is a passage down one level to the security room.

The decontamination terminal allows the player to activate the decontamination arcs to get rid of any rads acquired (access through the other exit of the room) and the security terminal lets the player end the lockdown and "obtain credentials" that open every door. No hacking required at either terminal.

It is advisable to backtrack through the control room and down the stairs to the reference point.

From there, it is only a short walk SE to reach the generator area (called "Turbine Hall" on the signs).

To come back from the generators, the best landmark is a blue office container on the NE wall, a few stairs up. It has a wall mounted turret. Walking NE at the right side of the office and jumping down to the lower level after the office container gives easy access to the hallway leading back to the reference point.

To come back from the reactor, the easiest way is to follow the catwalks to the highest point and exit through the emergency exit. The spiral staircase leads directly to the control room where the quest ends

Completion

 * Although the power plant can be activated once basic repairs are complete, finishing the job by repairing all the damaged areas will greatly increase the experience and caps reward received at the completion of the quest and provide +20% items at the conclusion (this isn't required to receive the generator plans; generator plans are always rewarded as long as the player does not already know the recipe).
 * Fixing up the power plant restores power to the region, as stated above. In Poseidon's case, this affects the:
 * Poseidon Energy Plant yard
 * Poseidon power substation PX-01
 * Poseidon power substation PX-02
 * Poseidon power substation PX-03
 * Wade Airport
 * Lakeside Cabins
 * Sutton
 * Grafton Steel
 * Billings homestead
 * Sunshine Meadows industrial farm
 * Once restored, the power plant will remain active for several hours. Reactivating it will require going through the motions of the quest again. Activating the power plants will also make the cooling towers dangerous, and anyone inside will take continuous damage from the venting steam.
