"Checking the east pier power distribution centres. Still nothin'. We're headed to the west pier now."
John Sheppard[src]

The Power Distribution Centre(s) are large rooms in Atlantis, capable of rerouting power across the city from the main power conduits. There are three known centres: East Pier, West Pier and the Main power room. After it was discovered that The Trust had planted a Bomb on Atlantis, these areas were checked for tampering.
