"If you cannot measure it you cannot improve it: the challenges of measuring and understanding the wind enough to use it effectively"
Wind power differs from other forms of power generation in some significant ways. Other methods often entail the exploitation of a well regulated resource to which generation assets are exposed under highly controlled conditions amenable to adequate inspection, repair and maintenance arrangements. Wind requires the exposure of many more assets to an uncontrolled resource that is highly variable and intermittent, in locations that are more difficult to access. The wind is always trying to break your wind turbine, and they are in places where it is not easy to fix them! The need to understand the wind conditions which turbines must endure, combined with the need make predictions to fulfil the requirements for financing projects, is driving the achievement of degrees of precision and detail in wind measurement and assessment in the wind industry not envisaged elsewhere. The availability of suitable light, robust and portable laser devices, or lidars, is helping us meet these challenges by enabling very sophisticated remote sensing of wind conditions. This allows us to measure more and guess less. Now, when we are measuring the wind, seeing is believing.

Dr Peter Clive has been associated with the wind power industry since completing his PhD in physics in 2002. He has had a central role in the development of the Galion Lidar, the 2nd generation wind Lidar system. This system enables wind fields to be surveyed with previously unobtainable detail and precision, revealing flow characteristics and structures that have a significant impact on the productivity and longevity of wind power assets. Peter also pioneered the introduction of response deficit analysis into wind turbine performance assessment, allowing the expertise and experience of wind analysts to be leveraged in the most focused and cost effective manner. His interests also include innovative resource assessment techniques that extract all the available information from the long and short term datasets from target and reference sites, minimizing project uncertainty and boosting project value. Peter has published widely on the subject of Lidar and has addressed many conferences around the world.
