2 About Pentalum Boost wind farms performance through optical wind remote sensing innovation Founded in Headed by experienced entrepreneurs and executive team. ABB as a strategic investor Development started in June 2010 Strong team specializing in Optics, electronics and fast processing for Laser based sensing systems. ISO900:2008 and ISO14000 certified. Pentalum ramps-up to meet the demand for SpiDAR in 2013 and Members of AWEA and EWEA commercially sensitive 2

3 What is a Wind LiDAR (Light Detection And Ranging) Optical remote sensing technology that can measure the wind profile in several different heights. 200m Aerosols drifting at the wind speed and direction Back Reflected Light Emitted Pulse commercially sensitive 3

4 Common Wind LiDARs (Light Detection And Ranging) Coherent LiDARs (Doppler based) V R N W s E Radial compone nt VR Complicate, Delicate, Very (very) Expensive commercially sensitive 4

5 Pentalum s Innovation A low cost, Accurate & low power wind LIDAR based on Direct Detection Technology The SpiDAR price is less than a 1/5 of any other LiDAR Ground Based SpiDAR commercially sensitive 5

6 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 commercially sensitive 6

7 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 m Easy to maintain commercially sensitive 7

8 Available Services Uniquely designed Power Pack A web based application to provide analyzed wind data and tools for remotely monitor and control the SpiDAR fleet commercially sensitive 8

9 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. commercially sensitive 9

10 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 commercially sensitive 10

11 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). * Estimations done by GENIVAR ** Estimations done by Garrad Hassan consulting commercially sensitive 11

12 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. ~200m commercially sensitive 12
