A 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.

– Ingame description

This facility supplies 3 Power; each assigned engineer provides +5 Power. Constructing a Power Relay in a room with an Exposed Power Coil will improve the relay's power output by +7.

Both the Psi Lab and Shadow Chamber use 9 or 10 power, which is more than the 7 bonus provided by a Power Coil. Power Coils appear lower in the Avenger, taking longer to reach. They also provide full power to any room built on it.

  • Build a Psi Lab or Shadow Chamber on a Power Coil, not the Power Relay.
