(PRWEB UK) 6 March 2013
Leading renewable energy consultancy Ecofys have released a comprehensive statement on the use of wind lidar, specifically ZephIR 300, to reduce uncertainty on wind farm developments. This statement is based on previously released recommendations from other consultancies and leveraging the company’s own experience with wind lidars which includes the recent multiple purchase of ZephIR 300’s by wind farm developer Raedthuys Group, currently on test at the Ecofys Wind Turbine Testing Services’ Test Site Lelystad.
The statement reports that “lidar wind measurements have been extensively verified against reliable reference anemometers over many sites” and “there is now industry consensus that lidar is a proven technology for wind resource assessment” referring specifically to the ZephIR 300 which is one of the two systems most tested to-date. It is reported that other lidar systems commercially available would only attain the same status if successful on further verification tests.
A key driver in the successful implementation of lidar on wind energy projects is the cost-benefit analysis of systems. Ecofys have confirmed that “the advantage of a well-designed wind measurement campaign is clear: reduced uncertainty leading to a lower equity investment and improved IRR.” Ecofys summarise the cost-benefit analysis on the attached graph (Figure 3).
On the announcement, Ian Locker, MD at ZephIR Lidar commented: “The positioning statement from Ecofys and the body of work that supports it is very positive for the industry as a whole. With a decade of wind lidar experience at ZephIR, we are confident that methodologies that include the ZephIR 300 ultimately lead to projects with reduced uncertainty and a greater return on investment. Ecofys, amongst a growing community of Banks Engineers who accept ZephIR data as part of a bankable wind campaign, are keen to promote that this is indeed correct.”

About Zephir Ltd.
In 2003 we released the first commercial wind lidar, ZephIR®, exploiting decades of research at UK government Research & Development establishment QinetiQ. Designed specifically for the wind industry ZephIR has paved the way for many of the remote sensing devices seen in the market today. Our original lidar technology continues to innovate with world firsts such as taking measurements from a wind turbine spinner and being the first to deploy an offshore wind lidar, both fixed and floating. ZephIR has also now amassed more than 3 million hours of operation across 650+ deployments globally spanning a decade of commercial experience. For wind measurements onshore, offshore and in turbine-mounted applications, ZephIR provides accurate, reliable finance-grade wind data.
Zephir Ltd. is a wholly owned subsidiary of Fred. Olsen Ltd. - established in the UK in 1963 with business interests primarily focused on renewable energy, including ZephIR. Visit http://www.zephirlidar.com for more information.
