At one time or another, just about everyone in the wind industry has seen the now famous image of the Horn’s Rev offshore wind farm in Europe’s North Sea. The effect one turbine has on the next, and the next, and on down the line can be quite dramatic – so noted at some projects that turbines furthest downstream from the wind, produce little to no energy and simply struggle to operate in intense turbulences, prematurely wearing down turbine hardware. Wake blocking effects have a huge impact on many wind project considerations: net energy estimates for financing, turbine spacing for project engineering, and operational strategies once the project is running.
