Wind turbine power curve verification (PCV) is a crucial measurement task in wind energy since it provides the means for performance monitoring and the basis of energy production guarantees. Offshore, nacelle lidars quickly replaced the traditional (and financially inviable, in this environment) meteorological masts for this purpose. As turbine rotor sizes increases, the need to measure the wind further away from the turbine in PCV (to reduce the blockage effect) increases as well, rapidly approaching the measurement distance range of state-of-the-art nacelle lidars.

For this reason long-range scanning lidars, due to their greater measurement range and versatility, can be considered a suitable alternative to nacelle lidars for PCV. One disadvantage, in comparison to nacelle lidars, is that they lack tailor-made standards or guidelines. This project has aimed to begin to address these shortfalls through the production of a best practice guideline document that highlights the items that need to be modified or completed for the use of transition-piece scanning lidars for wind measurement.
