DNV GL is calling on wind energy stakeholders to join a new Joint Industry Project (JIP) to explore the potential of using light detection and ranging (LIDAR) to measure wind speed Turbulence Intensity (TI) for various applications in the wind industry.
Measuring meteorological conditions such as wind speed and TI is essential for assessing and verifying the feasibility of new wind energy projects. For example, the data is used in the assessment of the wind resources at potential sites as well as to validate both turbine loads and power performance that are required for type certification of new wind turbines.
Currently, industry standards from DNV GL and the IEC specify that these measurements must be made using so-called meteorological masts. Recent advances in LIDAR technology offer a new way to carry out the meteorological measurements needed for turbine certification and site assessment at a much lower cost. The use of floating LIDARs also makes it possible to carry out measurements in previously inaccessible locations such as deep-water sites and enable more accurate energy yield assessment. As a result, LIDAR has the potential to help deliver significantly cheaper wind energy – both onshore and offshore.
By creating a Recommended Practice for LIDAR that is supported by players throughout the industry, the DNV GL-driven JIP aims to drive acceptance of LIDAR measurements and help reduce costs for turbine OEMs and wind project developers. The JIP is intended for wind turbine and LIDAR manufacturers, wind farm developers, universities and research facilities, consultants and measurement institutes that are looking for guidelines to use LIDAR TI measurements for different applications.
