Generators are the primary workshop item for power in a settlement.

Primary needsEdit

Generators are required to provide electricity to power objects such as lights, turrets, and water purifiers. Crafting them provides power, which can then be transferred to objects by connecting them with wires.

  • Large generators cannot be built under a roof meaning the barn structures or building something tall to fit it.
  • A windmill produces power and does not make any noise, but is noticeably more expensive in the power-to-cost ratio.
  • If several generators are attached to a single power pylon, the power value of that pylon would be the sum of the powers produced by the generators.
