Power Plant’s circuit is the longest walk of the blue tier — three buildings in strict order — but only one fuse. Since the Power Trip update put the plant at the center of the island’s grid, expect company on every run.

Before you go

Green card, blue card, 1 electric fuse, ~25 rad protection. A hazmat suit is the standard answer.

The route

  1. Corner building — switch under the stairs. Start at the three-story corner building: the first switch hides under the staircase. Flip it.
  2. Slanted-roof building — timer. Cross to the building with the slanted roof and activate the timer. The clock is running.
  3. Main building — green card. Move to the main turbine building and swipe your green card at the entry reader.
  4. First-floor switch. Just inside, flip the switch on the first floor.
  5. Second-floor fuse. Upstairs, place your fuse in the fuse box — the blue reader is now live.
  6. Blue door — swipe and clear. Swipe the blue card: inside, 4 crates and the red keycard.

After the run

The on-site recycler turns puzzle-route pickups into scrap before you leave. If the plant’s restoration events are active on your server, weigh staying to work the grid against banking the red card first — the card is the guaranteed win.

Power Plant — quick answers

What do I need for the Power Plant puzzle?
A green keycard, a blue keycard, one electric fuse, and about 25 rad protection.
What does the Power Plant puzzle reward?
A red keycard plus 4 crates (wood and military) behind the blue door.
Did the Power Trip update change the Power Plant puzzle?
The keycard circuit still runs cards-and-fuse as before — verified August 2026 — but the update made the plant restorable and the monument far busier. Re-check the room order on your first run of a fresh wipe.
Is Power Plant radioactive?
Yes, moderately — around 25 rad protection keeps you safe through the puzzle route. A hazmat suit covers it.
