This article is about the room. For the Energy Controller itself, see Main Energy Controller.

The Main Energy Controller is a major room in the Great Temple. It appears in Metroid Prime 2: Echoes.


Aside from the eponymous Main Energy Controller itself, this room is the location of U-Mos, the last active member of the Luminoth species, as well as the Light Suit, a Luminoth Lore Projector containing the Origins entry, and an access point for Aether's light-based teleportation system (after the energy network is restored). It is here where the conflict between Luminoth and Ing is explained, and where Samus receives the first upgrade to her Translator Module. Its Dark Aether counterpart is the Sky Temple Energy Controller, although due to the inverted nature of the Sky Temple it actually occupies the same space as the Sanctum.
