What is a Wind LiDAR (Light Detection And Ranging)

Optical remote sensing technology that can measure the wind profile in several different heights.

Aerosols drifting at the wind speed and direction

The Need for Wind Remote Sensing

• Accurate wind measurements are fundamental to the success of wind farm project.

• The uncertainty decrease by collecting high quality wind data from numerous points throughout the site and at appropriate heights.

This is difficult and expensive to achieve with traditional met masts

The Advantages of the Ground Based SpiDAR

• Deploy a met towers is

• Expensive & Hard to maintain

• Time consuming

• Permit issues

• Land owner issues

• Require FAA lighting

• Pentalum SpiDAR is

• Portable, easy to deploy

• No permit required

• Accurate measurement between 30-200m

• Easy to maintain

Deployments and Reliability

Highly reliable solution

• So far: ~18 months of accumulated operation of the

SpiDAR in the field

• About 50 units built and operated in the field worldwide

• Operation in a wide temp range of -25°C to +45°C

• Worked under fog, dust, low clouds, rain, snow and hail.

Resource Assessments Using Multiple SpiDARs

• Deploy one or many SpiDAR sensor to reduce the uncertainty

• The 1 year clock is started ticking …

• Once you have a permit, Add a small Met mast (50-60m) for 3-6 months of measurements parallel to the SpiDAR systems

50-60m Small met mast

The Value of Accurate Wind Measurements

• Accurate measurements reduces the uncertainty in predicting how much power the wind farm will produce over its 20 years operation lifetime

• Up to 6%** decrease in measurements uncertainties ($4.5M in NPV)*

• High resolution wind speed measurements are needed for accurate siting and type selection of the wind turbines in the field

• Up to 5%** increase in wind farm total output power by better micro-siting (1% is equal to $2M/year for a typical 100MW WF).

SpiDAR for Wind Turbine Control

Provides a real-time, accurate measure of the head wind to allow the turbine to better face the wind and prepare for wind shear and sudden wind gusts, and reduce loads.
