Valley Windworks is a power-generating station using tons of massive windmills, found at the southeast of Route 205. The wind energy is used to turn the turbine of the windmill to generate electricity. Team Galactic wanted to use this energy for their plans. This is the only place where you can catch a Drifloon on fridays.
When you first visit this place, a Galactic Grunt should stand at the entrance. Battle him. However, when you battle him, he will go inside quickly and lock the door. You then have to get the Works Key from the Galactic Grunts at Floaroma Meadow.

After you get rid of Team Galactic, the man's daughter you met earlier will run back to him. The man will thank you and say something about a balloon Pokémon will come again. Refer below. The balloon Pokémon is Drifloon. It will visit every friday after defeating Team Galactic.
After you defeat Team Galactic, a Drifloon will appear in front of the Valley Windworks building. It will appear every Friday and will be gone the next day. So if you want to catch it, wait until Friday or change the day of your Nintendo DS. Drifloon will be at Level 22.
