The Front Cover

It has been six years since the first issue of Windtech International, which featured the public release of a revolutionary and groundbreaking new technology – lidar. Today, we look back over those six years to see how the technology has fared and what the future holds. Natural Power recently launched the new ZephIR 300. On page 6 you will find the full article about the new device.

The Front Cover

Throughout the world many of the best wind sites have been built out, leaving the more challenging sites – those with lower wind speeds, more complex terrain, or greater distance to the grid – to be developed. Recently NRG Systems and Leosphere introduced their second generation lidar, the WINDCUBE v2. In the article on page 7 the authors talk about reducing uncertainty and cost with lidar remote sensing and the WINDCUBE v2.

Canary Islands plans to install 440MW of wind energy. Recently Endesa was awarded 69.3MW of the 440MW of wind power capacity allocated during the round of tenders held by the Canary Islands’ Department of Industry. The image at the cover shows the Parque Eólico at Los Valles near Teguise (Lanzarote) and has a capacity of 7,65MW.

The Front Cover

In this issue we have several articles stressing that new development is necessary for growth. Lueder von Bremen (page 6) writes that the central insight is that wind, solar, pan-European transmission and storage form an interdependent system. This system has to be optimised according to the specific costs of each of these technologies. Like other industry leaders he argues for a European Supergrid. The image shows the annual average wind speed (metres/second) in Europe in 2007 at 90 metres height.

Most wind farms are located in open, lightning-prone areas and have turbines reaching many tens of metres into the sky, lightning safety is a major concern for wind farm operators. The article on page 7 will provide insight into practices that are currently being used by many leading wind farm power companies to enhance operational efficiencies and ensure employee safety.
