Assessment of Meteorological Site Conditions

  • When EnBW Systeme Infrastruktur Support GmbH required an assessment of the meteorological site conditions at the site of the „EnBW Baltic 2“ wind farm in the Baltic Sea, a thorough analysis in compliance with international regulations was essential. That is why EuroWind, co-operation partner of TÜV Rheinland, was the right choice for this project, by virtue of its wide experience in wind resource and energy yield assessments since 2001.

    Initial situation and requirements

    EnBW Erneuerbare Energien GmbH, a subsidiary of EnBW Energie Baden Württemberg AG, is consequentially developing the area of offshore and onshore wind energy. Their four large offshore wind farms in the North and Baltic Sea with a total of 1,200 MW belong to the most important wind energy projects in Germany at present. They have taken EnBW Baltic 1, as the first commercial offshore wind farm in Germany, into operation in 2011. For the assessment of the meteorological conditions at the EnBW Baltic 2 wind farm site in the Baltic Sea, EEE required a professional partner for top quality assessments in the wind energy sector.

    Solutions, results

    EnBW Baltic 2 is the first project in the Baltic Sea combining offshore grid
    connection of wind power plants with cross-border transmission capacity.
    A study was conducted to estimate the meteorological site conditions at EnBW
    Baltic 2 with regard to the design basis associated with the project certification.

    The analysis was performed with regard to all relevant offshore guidelines. For
    the site assessment, the measuring data of the research and measuring platforms Darßer Schwelle, Arkona Becken, and FINO2 were used. These were provided by the BSH. In addition, data of the 3D meso-scale HiRLAM model were applied. Along with application of the extreme value theory and bootstrapping, the necessary results were obtained and an assessment report for the design basis created.

    With the data gained from the assessment of the meteorological site conditions, it is possible to optimize the wind farm for later stages in the project, by comparison with other wind energy plants and anchorage conditions.

    Did you know

    The construction of 80 wind turbines with a total capacity of up to 288 MW is possible at EnBW Baltic 2 wind energy park.
