• Gravity jacket concept for cost-efficient foundations
• First offshore installation of SWT-7.0-154 wind turbine including 66kV transformer, cable and switchgear
• Cable in pipe for cost-efficient cable systems
Four wind turbines and related equipment take a large step into the future of offshore wind technology: Nissum Bredning Vindmøllelaug and Jysk Energi placed the winning bid for Nissum Bredning Vind following a tender from Danish Energy Agency’s (DEA) tender for the construction of the 28-megawatt pilot project in northern Denmark. The final investment decision has been made for the project, which includes important tests for future offshore wind technology: Siemens will not only supply its new 7-megawatt direct drive wind turbine, but also an innovative and cost efficient gravity jacket foundation solution, its new 66kV voltage solution including a new transformer, cable and switchgear systems, along with further innovations regarding tower and controller settings.
The commercial aspect of the offshore wind technology to be tested in the project is expected to show a significant positive impact on the Levelized Cost of Electricity (LCoE). The DEA believes that the elements to be tested at Nissum Bredning will bring significant savings within both capital and operating costs. A major contributor is Siemens’ innovative gravity jacket foundation concept, allowing the construction of jacket foundations at lower costs than monopiles. Foundations generally account for approximately 20-30% of the costs of an offshore wind power project. Building on its innovation strengths and extensive knowledge of the necessary supply chain, Siemens will continue to run a series of projects out of its R&D functions in Brande and Vejle, Denmark, to lower the cost of energy from offshore wind.
