America's NRG Systems, a leading manufacturer of wind measurement equipment, is teaming up with the young French company Léosphere to market the latter's lidar remote sensor, known as the Windcube. The two companies will set up a 50-50 joint venture, with NRG covering the Americas and Oceania, while Léosphere concentrates on Europe. "It is the next logical step for NRG to team up with lidar," says NRG president Jan Blittersdorf. The Windcube's pulsed laser system takes measurements at between 40 and 200 metres, while conventional anemometers, such as those used by NRG, only operate up to 60 metres. As hub heights steadily increase, however, measurements need to be taken at greater heights to obtain more accurate resource assessment and reduce uncertainty. The combination of traditional anemometry with remote sensing technology "is pretty much a no-brainer," comments Andrew Garrad of Garrad Hassan, a UK-based consulting firm. To date, Léosphere has 50 Windcube units operating worldwide.
