Which may be all the time certain critical systems need to recover or drop into safe modes. But most blackouts are caused by infrastructure failures, not power plants shutting off. During the blackout on the East coast of the US in '03 (?), it was caused by a fault in the lines (generaly speaking). The power plants kept producing power, it just didn't go anywhere. All the batteries in the world wouldn't have made a difference.
Batteries are like this are designed to help with brown outs, not black outs, to buffer demand as needed.
