Wind Lidars, like the ZX 300, are becoming essential tools for providing high-quality finance grade wind data crucial for Energy Yield Analysis in wind farm development. Two key trends have emerged in recent years:

1.Increased Autonomy: Lidars are now being deployed at various times, locations and heights, unlike traditional met masts.

2.Remote and Challenging Locations: Due to constraints in more populated areas, project sites are moving to more remote and    difficult-to-access locations.

These trends highlight the importance of continuous data delivery from Lidars. Interruptions can lead to extended campaigns or increased measurement uncertainty. Additionally, remote locations raise the cost and delay of site visits for repairs or maintenance. Therefore, it's crucial for developers to rely on Lidars that maintain high system uptime, even in harsh environments.

Accurate wind speed measurement at wind turbine hub heights is critical for performance verification under IEC 61400-50-3 and IEC 61400-12-1 standards. Traditional meteorological masts with cup anemometers become increasingly impractical due to rising turbine heights and associated costs. This study evaluates the performance of ZX TM, a nacelle-mounted, Continuous Wave (CW) Doppler Lidar, as a high-accuracy alternative for power performance assessment [8]. By eliminating the need for tall met masts, nacelle-mounted Lidars streamline the testing process and provide robust data for wind turbine performance validation.

This paper is designed to be a practical guide for using nacelle-mounted Lidar in IEC-compliant power performance tests. By referencing a core set of validation documents and procedures, as well as showcasing evidence from the industry supporting the adoption of such technologies, this work aims to provide clarity and confidence to wind farm operators and turbine manufacturers considering Lidar-based measurements.

While wind Lidars like the ZX 300 are widely known for their role in the wind energy sector, they’re also tackling a other world challenges - namely methane emissions.

In partnership with TotalEnergies, our wind Lidar is being used in a whole new way: to provide the precise wind data needed for accurate methane monitoring. Why does that matter? Because methane is over 25 times more potent than CO₂ at trapping heat in our atmosphere.

As the shift towards renewable energy gains momentum, innovative hybrid development projects are emerging to maximise efficiency, reliability, and cost-effectiveness. ZX Measurement Services looks at how integrating wind and solar energy assessments can enhance output and stability, exploring essential measurement strategies for optimising these systems.
