How do I turn back the power in Nuka world? (spoilers)

[Silver]

so i really have to capture some settlements for the raiders in the commonwealth or kill everyone to be able to flip the switch in the nuka powerplant?

and if i dont do that, going there (to the plant) is a waste of time?

also i dont seem to recall the trader lady telling me to turn on the power after having freed them so I feel like this is pretty confusing for people who dont look everything up in the wiki/guide

If you eliminated the raider leaders turn in the quest to the doc lady, she is the one who will suggest eliminating the leaders in the first place, then go to the power plant, the door at the top will be unlocked and turn on the power. no key required.

so once you shortchange the furry faction enough times, they'll hole up in the power plant ie crawl under the porch and wait to die. just put 'em under & get the key from Mason's corpse.

There is a decent simple mod which removes the raiding of the your settlements, allowing you to finish Nuka World without doing the raiding part. Then you can finish up whatever you want in Nuka World before siding with the enslaved traders and taking out the gangs. You just talk to Shank and it skips straight to Power Play. If you decide that you want to raid, you can talk to Shank again. It also keeps Preston from becoming mad at you for raiding your own settlements. You get to do power play and turn on the power.

go to nukatown usa market there is a trader that will suggest killing all the raiders that quest lets you turn on the power to the park but honestly i would wait a few days to do that just so you can do the arena side mission were you kill like 7 challengers to the park

Yes, you have to get to the end of the storyline one way or the other (either supporting the raider gangs or destroying them) to restore the power supply to Nuka World.

[Wasteland Project]

It is advisable to follow the storyline and related quests starting from:
The Grand Tour ---->
A Magical Kingdom
A World of Refreshment
High Noon at the Gulch
Safari Adventure

----> Star control
found in the quest locations above the star core
Star core extra

The Commonwealth has nothing to do with it, you have to go to Nuka World. The raider settlements in the Commonwealth is a separate quest that will take over following the storyline indications of raider Porter Gage.
Talking to Porter Gage you will have to decide whether to become a raider or free the settlers from Nuka-World.
Nuka-World is a dlc with an irreversible ending, if you team up with Porter you will definitely become a raider. The point of no return is the Open Season quest indicated by Nuka World vendor Mackenzie Bridgeman.
Preston won't be hostile if you become a raider and you will claim the settlement, it must be said that if you don't use the "psychic" preparations but you attack the Commonwealth settlements to conquer them, the turrets you have installed will defend the settlement. Without "chemical bombs" the turret system in my settlements destroyed me in seconds.

Unfortunately, yes; having them occupy an uninhabited location still counts as bringing the raider gangs to the Commonwealth and betraying the Minutemen (if you've joined them).

Although we don't see it directly in-game, in story terms the raiders are presumably supposed to be going around raiding the Commonwealth from their outposts.

Yes, because as Douglas said, they presumably go around raiding the area. Also, in addition to taking over 3 locations to serve as raider outposts (which can all be uninhabited initially), another settlement (which must have actual settlers in it - it can't just be an empty lot) has to be turned into a raider vassal.

Nuka-World is a dlc with an irreversible ending, if you team up with Porter you will definitely become a raider. The point of no return is the Open Season quest indicated by Nuka World vendor Mackenzie Bridgeman.

If you side with the Raiders and totally finish their questline (which includes setting up raider outposts in the Commonwealth), you can still always go back and finish off the other 2 gangs. And if you do this before becoming the Minuteman general, Preston doesn't ever mention it and can still be your companion.

I've had a few inconsistencies with it working when I didn't receive the quest to destroy the other gangs from Preston himself (unfortunately I can't remember the details of what went wrong since it was quite a while ago that I did it any other way, but I didn't end up with the desired result).

So if there is any trouble on that front, I'd specifically suggest talking to him.
