There is no way in hell you can run a modern fab using on-site power anymore. Maybe in the 80s/90s, but now you got things like EUV light sources that require megawatt-class power delivery all on their own. Just stepping back 1 generation to DUV and you are "only" talking ~100kW per machine, which is still insane.
What would probably happen is a special grid arrangement. If you are going to build eleven of these things, entire power plants, switchyards and transmission lines will need to be constructed ahead of time. They will likely need to run isolated from the broader grid in some manner. I cannot imagine Samsung executive management agreeing to this many factories (even with subsidies) unless some guarantee could be made WRT power delivery.
