> Nearly all of the purposes for these flywheels could equally be met with existing infrastructure with software only changes. While that's true, sometimes it's easier to have a single-purpose infrastructure, so that you don't have conflicting requirements. For example, if a wind farm needs to feather its turbines due to excessive wind (which could damage the turbines), that could conflict with a simultaneous objective for frequency regulation.
