The Capacity Factor of a wind farm is the ratio of actual energy produced to the hypothetical maximum possible (i.e., the energy produced from continuous operation at full-rated power). Most wind farms reach Capacity Factors of 25-40%. In many of these, they operate at full capacity less than 5% of the time. Nevertheless, farms must size the substation and transmission line for the full-rated power.

Wind Harvesters installed under and around the existing turbines will use existing roads, transmission lines, storage batteries, etc,  and capture the mid-level wind unavailable to tall turbines. Making double use of existing infrastructure is why these projects can return the most energy per money invested.
