The Power Plant was a mutant-owned and operated bar and club located in Mutant Town and was directly across the street from the original X-Factor Investigations Headquarters. The bar was run, and possibly owned, by Lefty. The X-Factor Investigations staff would frequent this bar quite often.
The Power Plant stayed open for a while after M-Day, but closed down when many of the Mutant Town citizens began to move away. The Power Plant building was then used as a Headquarters for Arcade, but was later destroyed with the rest of Mutant Town.
