Power Relay is a Facility in XCOM 2. Every facility aboard the Avenger requires power to remain operational. Building relays will increase the total power output of the Avenger, allowing for further expansion and upgrades. 

Power Relay Information

  • Staffing Bonus: Staffing one of your Engineers here will give +5 Power. After completing the upgrade to Power Conduit, you may staff 2 Engineers here for an additional +5 Power.
  • Staffing Engineers here early on in the game will be vital to ensuring you have the adequate amount of power needed to construct future facilities.
  • Constructing a Power Relay in an empty room with an exposed power coil will improve the power output of the relay by 7. Exposed power relays appear at random and are usually located on the bottom of the Avenger.
  • A bug in the game when upgrading a Power Relay built over an exposed power coil causes it to show that the upgrade will add 7 more power than it actually does.
