**5. Moving forward**

As the wind industry matures major wind farm developers continue to add to their experi‐ ence in wake loss estimation. These individual organizations continue to refine their predic‐ tions and add to databases based on this experience promoting an improved understanding of wake effects and reduced uncertainty in the planning stages. Academic research contin‐ ues in this area. However, strong demand continues for larger and larger wind farms, par‐ ticularly offshore. With increased wind farm densities both on and offshore, inter-farm wake dynamics have become a growing concern. Subsequently, there is a notable need for highly reliable wake mixing and long distance wake propagation models. As evidenced in this Chapter, opportunities remain for continued commercial wind farm optimization.
