Is there any way to access the other power plants in the Lumiose Badlands?

Finished that portion of the game, where you clear out the power plant full of Grunts.

Can I access the other power plants in the region? It tells me the "door is shut tight".

There is some speculation/rumor that the doors may lead to events/event pokemon that have yet to be released but for now they are just shut tight. Game Freak and Nintendo have done stuff like this through the whole history of Pokemon but then again it may just be like the truck in R/B/Y(a big red herring)

from what i know you can't get in even after you beat the game sadly.I know because i beat pokemon y already and it might somehow be related to Volcanion Hoopa and Diancie
