I remember from somewhere that the water valves on a large hydro project (>10ft)
would affect the utilities such that they had to buffer the energy.

Motor/generator/flywheel sets would slowly be brought up to speed then
the energy was dumped into the vane control motors.

This would distribute the power demand spike over time.
