How To Turn on the Power in Nuka World
Turning on the power in Nuka World requires the player to complete a few steps. First, each section of the park must be cleared, as outlined in the mission The Grand tour. Clearing and claiming all five sections of the park and speaking to Gage will result in a relative rise in stability and unlock an important choice.
After speaking to Mackinzie Bridgeman in the Nuka-World USA market, the player can choose to engage in the Open Season mission. This tasks the player with hunting down the bosses for all three gangs which will incidentally set every gang member in Nuka-World against the player). After defeating all the gang bosses and clearing the streets of enemies, the player can then progress to turning on the power.
Alternatively, by helping the Raiders and conquering three Commonwealth settlements, the player can trigger a gang uprising. After putting down the uprising, the player can then continue to the steps below.
Turning on the Power
Once the prerequisites above are met, head to the north-west section of the Nuka-World map. The road looping north leads to a Power Plant. You can easily spot it on the hilltop towering above the rest of the park.
The Nuka-World Power Plant entrance is around the back end of the building, a blue door near the ground floor. Depending on the choices you’ve made, the area may be inhabited by either Ghouls or gang members.
Advancing through the plant, your ultimate goal is the roof, but you’ll begin by heading downstairs. The course winds through the plant, with tracks heading down, up, down, and up again.
Note that there’s a suit of Power Armor hidden on the bottom floor behind this locked door.
Also beware the Bloated Glowing Ghoul you may encounter… he’s carrying a Fat Man. Knock him down quickly and from a distance.
When you reach the area near the pool table and employee terminal. look at the upward facing ramp hidden nearby. In the dark room beyond is a ladder to the roof.
Climb to the roof and loop around to the control room. The big white button will restore power to the park.
