Brazil’s Largest Wind Developer Adopts Remote Sensing Systems from Second Wind


BOSTON, MASSACHUSETTS, USA and SAO PAULO, BRAZIL -- Brazil’s largest wind energy developer has adopted Second Wind’s remote sensing technology as part of its standard practice in wind measurement. The agreement by São Paulo-based Casa dos Ventos Energias Renováveis to purchase Second Wind's Triton® SoDARs and Pentalum Technologies Ltd.'s SpiDAR™ LiDARs represents a significant endorsement of remote sensing technology as an essential complement to meteorological tower data in wind resource assessment.

Remote sensing systems calculate wind speed, wind direction, and other wind data by measuring reflections or echoes of sound or laser pulses. Triton and SpiDAR are easily relocated and provide wind measurements up to and above a commercial wind turbine's hub height. This answers the wind industry's need for data at higher heights and more locations than can be cost-effectively acquired using met towers.

The decision by an influential Brazilian wind developer to use remote sensing -- Casa dos Ventos deploys 100 meteorological towers annually -- reflects the widespread acceptance of SoDAR and LiDAR technology by the wind power industry.

'The use of remote sensing systems such as SoDAR and LiDAR contribute to a better valuation of our wind resources and a lower uncertainty on the energy-output projection of our wind farms,' says Lucas Araripe, Director of Business Development at Casa dos Ventos.
