The backup power supplies for these types of facilities are actually generators powered off gasoline or diesel, not just batteries, and can theoretically run forever (or at least as much fuel you can get).

You cannot backup power a whole modern fab, unless you build a small power station just for it. UPSes there are just to keep cleanroom clean, and most critical processes which can't be gracefully shut down.

  Although at these scales, a CCP at 400MW output is "only" ~$300M, so building that small power station might not be that big a deal compared with the cost of turning off?

    I believe things are moving progressively in this direction.
