LIDAR Systems for Wind Measurement

The wind energy industry is advancing by leaps and bounds, but the key question remains the same: how can we ensure maximum accuracy and profitability in wind resource measurement? For decades, the traditional answer has been the meteorological tower—an indispensable tool, yet one with evident limitations in an increasingly competitive market.

The new era of wind energy demands more agile, safe, and efficient solutions. This is where LIDAR (Light Detection and Ranging) technology redefines the standard of measurement.

 

What is LIDAR technology?

Imagine a radar, but instead of using radio waves, it uses invisible laser light pulses. The LIDAR system emits millions of these pulses into the atmosphere, where they bounce off tiny particles of dust and moisture floating in the air. By analyzing the time it takes for the light to return and how its frequency shifts, the device calculates wind speed and direction with millimeter precision.

It is a remote wind measurement method that creates a detailed wind profile, not just at a single point, but at multiple heights simultaneously. This overcomes the limitation of traditional anemometers, which only measure at the point where they are installed. The laser wind sensor allows you to see the wind in a completely new way.

 

Applications of LIDAR in Wind Projects

LIDAR is much more than just a wind meter. Its versatility makes it an invaluable tool throughout all phases of a wind project, solving specific problems and providing crucial data.

For example, during site assessment, it enables the collection of a complete and detailed wind profile at any height and in complex or hard-to-reach terrains, where building a tower would be unfeasible, costly, or dangerous.

It is also used in the calibration of wind turbines to optimize their power curve, as well as in continuous monitoring to oversee the performance of already operating wind farms. Its ability to measure in real time makes it ideal for offshore project development, where meteorological towers are virtually impossible to install.

 

 

LIDAR vs. Meteorological Towers

Although towers have long been the foundation of wind measurement, the balance is increasingly tipping toward LIDAR due to its clear advantages. LIDAR completely eliminates the risks associated with working at height, both during installation and maintenance.

Its setup is fast and can be operational within hours, significantly reducing deployment and operating costs—unlike a tower, which requires permits, construction, and a lengthy process.

LIDAR systems are portable and easy to relocate, making them ideal for measurements in remote or rugged terrains, while towers are fixed structures.

In addition, LIDAR provides measurements at multiple heights up to 300 meters, delivering a three-dimensional wind profile. Finally, it leaves only a minimal visual and environmental footprint, with no need for foundations or large structures.
