edit: otherwise I'm not getting what the entire article is about. it's as contrary to what I know about datacenter design as it can get.
it's.. just wrong.
because if so, I have some nice east-european guys to teach them proper load-balancing.
Then again, some data centers just use re-generation from giant flywheels, where the grid powers the flywheel to build up inertia, and thus load can be smoothed that way. The flywheels need to keep running at 60 Hz for at least 30 seconds to give the Diesel generators time to start, should the grid fail.
Run a flywheel at the main transformer, run batteries at your PDC and add supercaps at each point of load, and you may very well be able to show a much smoother load to the grid.
