There aren't a lot of mountains or really any kind of elevation changes in SW MN (where most of the wind turbines are) so that means towers or some other method of creating elevation. I'm guessing you'd need either many small tanks or some really really huge ones to store any measurable amount of energy. Maybe there's some way the water storage could be built into the turbine's tower to save on costs.
Like some others have said, this works best for places with some hills or mountains.
