Siemens to Build Offshore Wind Project with Innovative Foundations and Cable Systems

Gravity jacket concept for cost-efficient foundations

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 RD functions in Brande and Vejle, Denmark, to lower the cost of energy from offshore wind.

The four Siemens SWT - 7.0 - 154 wind turbines will be grid connected using a new cable and turbine concept with a 66kV voltage. Siemens expects this to be the standard voltage for future offshore wind power plants. This higher voltage results in lower costs for cabling and lower losses. Additionally, cable in pipe solutions allow for simpler cables to potentially be used between turbines. Further material savings will be provided by the slender tower concept using prototypes of a new lightweight turbine tower especially suited for jacket foundations.

“We are proud to be part of Nissum Bredning Vind offshore wind power plant. Since the  Danish  Ministry  of  Energy  tendered  the  project as  an  official  test  bed  for  new technologies and integrated design, we’ve looked forward to this exciting project,” says  Michael  Hannibal,  CEO  Offshore  at  Siemens  Wind  Power  and  Renewables Division.  "This  gives  us the  opportunity  to  simultaneously  test  and  promote  our innovations to achieve further cost reductions in offshore wind."

Nissum  Bredning  Vind  offshore  wind  power  plant  will  get  support  by  receiving  a guaranteed feed-in tariff of DKK 0.7/kWh (EUR 0.09/kWh) for the initial 10 years for the  first  50,000  full  load  hours  of  operation.  Turbine  installation  is  scheduled  for summer 2017. Commissioning will be in the third quarter of next year.
