Independent energy expert and certification body DNV has completed the formal IEC classification of the ZX 300e ground-based wind lidar, confirming the system achieved the highest performance outcome under the IEC framework.
The classification was conducted in accordance with the full methodology defined in IEC 61400-50-2 – the international standard governing the use of ground-based remote sensing devices for wind measurement. According to DNV, the ZX 300e achieved 0% standard uncertainty and a corresponding 0% accuracy class under the standard.
The work follows earlier industry reporting on what was described as a world-first IEC certification for a ground-based wind lidar.
In the latest announcement, DNV confirmed validated performance of the ZX 300e across a 20-200 m height range under the IEC framework. This aligns with the increasing hub heights of modern utility-scale wind turbines where measurement at higher elevations is becoming critical for accurate energy yield assessments.
DNV said the classification programme included multiple test sites, several reference masts, extended measurement campaigns and a wide range of environmental conditions. The dataset provided for evaluation exceeded the minimum requirements of the standard, enabling performance assessment across a broader set of scenarios than is typically available.
