The superposition of wind power and existing load yields the crucial variable "net load," which is defined as the load minus the wind. Research findings and actual operator experience agree that the variability of net load exceeds that of the system when wind was not present, thus confirming the need for greater system flexibility under conditions of high wind penetration. Further, the mostly diurnal pattern of onshore wind means wind resources tend to peak when load is at its minimum. Existing commitment constraints imposed by thermoelectric baseload units means that even without transmission bottlenecks, wind power sometimes would be spilled to prevent minimum load problems. Thus, wind requires system flexibility in the form of ramping capability and lower minimum load; more flexible systems should see a lower balancing cost for wind. Many systems already have a large degree of flexibility which can be utilized to integrate wind.
