There are a lot of possibilities. But for a big grinder, I wouldn't want to use a wimpy timer; I'd use something more substantial.

As for power, we'll need something reasonable, like the Hoover Dam.

Since you'd need to pull these shots back to back, a nice commercial circuit or two: 30 Amp circuit x 230v x 6000 = 41 MWatts (worst case of course when you turn it on first thing in the morning).

The air conditioner should of course be sized appropriately.
