With a big flywheel setup, it might take up less space and cost less than a huge AGM battery plant, but you had better be *really* *confident* in the maintenance, load testing and quality of your generator... The ones I have seen are good for 30 to 60 seconds of load buffer, maximum, just enough time for a big diesel generator to start up and get slightly warmed up before the load transfers onto it.
