German Ministry Supports BBB's Remote Sensing Project in Brazil

SÃO JOSÉ DOS CAMPOS, Brazil -- To establish laser based wind measurement technology and to implement a verification site for remote sensing devices in Brazil are the goals of the project, with which BBB Umwelttechnik GmbH (BBB) has qualified for the inclusion in the "dena Renewable Energy Solutions Programme". The programme is supported by the Federal Ministry for Economic Affairs and Energy and has the aim to financially promote German companies in opening up new markets and facilitate the transfer of technology and know-how.

The basic idea of BBB's project is the development of a verification site in cooperation with the University of São Paulo which will be used for both commercial purposes and scientific research. To this end a met mast and a remote sensing measurement station are to be installed at the site. Professor Ildo Sauer, director of the Institute for Energy and Environment strongly supported the project idea. At his University, Sauer is implementing a wind energy research cluster where students are trained to meet the demands of the Brazilian wind industry.

Laser-based LiDAR systems (Light Detection And Ranging) represent the state-of-the-art in wind measurement technology. Compared to the traditional measurement method by cup anemometers installed on met masts they provide a number of advantages: while having the same precision, LiDAR systems can be operated without permission and can easily be moved on the project site. But to ensure reliable data acquisition by means of a remote sensing device, it has to be verified against met mast data before and after each measurement campaign. For that purpose the verification site will be used.

BBB, which in Germany has 30 employees and recently has opened up an office in São José dos Campos, is using LiDAR technology since 2011. With six company-owned systems it is Germany's leading wind resource specialist in this technology. This expertise shall now be introduced into the Brazilian market and forms the basis for the project. BBB employees will hold guest lectures at the University and coordinate application-oriented research projects. Furthermore pioneer work will be done for the development of norms and standards in Brazil in the area of wind resource evaluation.
