This load balancing can be up as well as down if a windfarm is operated at 90% design efficiency so that it can instantaneous ramp up to 100% or down to 80% in response to load balancing requirements.
You might want to ask - why run a windfarm at 90% in the first place - and the answer is only if wind penetration is so high that you don't have sufficient gas load balancing available, or the baseload plants are having difficulty adjusting in a timely manner.
My point is that windfarms don't engage in load balancing because it makes sense to run them at 100% for carbon footprint, capital asset utilisation, and income maximisation in a FIT pricing regimen. However, technically, there is no reason why higher wind penetration levels must result in increased load balancing concerns provided you are prepared to pay operators compensation for operating their plant at less than 100% potential output - (which is presumably what makes gas turbines economic?).
(PS - this is me testing a theory, not speaking from knowledge or experience! Please correct me if I have gotten this all wrong)
