Re: Look to Dinorwig
"With all six units synchronised and spinning-in-air (water is dispelled by compressed air and the unit draws a small amount of power to spin the shaft at full speed), 0 MW to 1800 MW load can be achieved in approximately 16 seconds."
Wikipedia article on Dinorwig. The same source gives 75 seconds from start to sync without such preparation.
