Description

Power Relay is the facility that powers the Avenger and every single room you decide to build. Lack of power may be the reason that your Expansion is halting but that should not be the case. In all of my playthroughs across every difficulty including an Iron Man one, I did not even upgrade the Power Relays, but I was still able to finish the game. The truth is, it is always the lack of supplies that will hinder you from expanding your base because it is needed for everything. Building the Power Relays on rooms with exposed power coils will provide additional seven (7) power. The Elerium Conduit is not really worth it early, or mid-game, because Elerium Crystals are better spent elsewhere and 150 supplies are a lot in the beginning of the game. However, if you are bumping into several missions that give hefty amount of supplies, feel free to build this. If not, prioritize spending your supplies to Guerilla Tactics School upgrades, or your soldier’s gear.

The reasoning behind putting up several power relays instead of upgrading one is very simple: by excavating you are gaining more supplies. The time spent in building all of these upgrades are better spent on excavating because it will net you more supplies, you gain more and spend less. Building more Power Relays means more rooms are excavated, more supplies are gained, it is otherworldly efficient to build more Power Relays than upgrading them.
