Does the NEC and/or NFPA 70E have jurisdiction within any Utility owned Substations i.e. Control Buildings, Meter Houses, etc... and if so what is the article?

The NFPA 70 (a.k.a. NEC) applies to places where it says it applies, outlined in the very beginning, Article 90.2 (A), then in (B) (5) it SPECIFICALLY excludes electric utilities.

NFPA 70E is not "jurisdictional" in any case, it's a suggested standard of safe practices. Utilities must provide safe electrical work practices just like anyone else and fall under jurisdiction of OSHA, but generally OSHA is not going to challenge a Utility's safety standards and practices against a generalized standard such as 70E.
 
I was told in a code refresher class last year, but I can't find the reference that NEC had expanded into control houses, relay building, etc.... even for utilities. I am familiar with your reference above but the instructor (who is no longer around to contact) had expanded the scope a little bit further. So I was curious if anyone else had knowledge of the reference he was referring to. Thank you.

It has not recently expanded. However the code itself does say this.



90.2 Scope.
(A) Covered. This Code covers the installation of electrical
conductors, equipment, and raceways; signaling and communications
conductors, equipment, and raceways; and optical
fiber cables and raceways for the following:
(1) Public and private premises, including buildings, structures,
mobile homes, recreational vehicles, and floating
buildings
(2) Yards, lots, parking lots, carnivals, and industrial substations
(3) Installations of conductors and equipment that connect
to the supply of electricity
(4) Installations used by the electric utility, such as office
