I made it to Route 13. The area was quite large and it took me quite some time to explore it all. There was a Team Flare Grunt, so I battled him. I was then able to get the pass that allowed me to go inside the Kalos Power Plant. The Power Plant had been taken over by Team Flare, so I had to fight many Flare members in order to get the power to Lumiose restored. By the time I was done with the Power Plant, my entire team was above level 40.
I then went back to Lumiose now that the blackout was over. I saw the tower light up, then I went to the Pokemon Center.
