Given how bad a power fault is on a fab, chemical processes that can't be interrupted and air filtration and pressure systems, I'd put a redundant Tesla battery as the UPS to a fab, anywhere.

I would install large diesel generators well before anything from tesla if I wanted a reliable power supply

Generators would have to kick on and over, with a battery backup it could be pass through. Tesla was used as a representative example.

Actually any decent backup system uses combination of both ...

Run on generator the whole time if you have an unreliable power system like India.
