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 28MW pilot project in northern Denmark. Siemens will supply its 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. The four Siemens SWT-7.0-154 wind turbines will be grid connected using a new cable and turbine concept with a 66kV voltage. 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. 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. Commissioning will be in the third quarter of next year.
