DanTysk supplies wind power Fifth German offshore wind farm goes online
The offshore wind farm DanTysk, located 70 kilometres to the west of the island of Sylt, started feeding in electricity to the grid on 3 December. The 80 wind turbines will go online successively. DanTysk is expected to be fully grid-connected by spring 2015.
A total of 88 power cables with a total length of 108 km transport electricity supplied by every wind turbine to the wind farm’s own substation via the 33kV AC voltage level. From here, the alternating current is transmitted, at a higher voltage level of 155 kV, to the converter station of the grid operator Tennet. In order to then transport the electricity onshore to Büttel, Schleswig-Holstein with as little loss as possible and over a distance of 200 km, the alternating current is converted into direct current in the Tennet converter station.
“We are very happy to announce that DanTysk has started generating electricity. With this project, and its sister project ‘Sandbank’ following as early as 2015 we and our partners Stadtwerke München are making a major contribution to the development of renewable energy in Germany,” said Gunnar Groebler, Head of the Renewables Business Unit for Vattenfall’s Continental/UK region.
The wind farm DanTysk comprises 80 3.6 MW-class wind turbines, all built by Siemens. DanTysk is being built on an area of 70 square kilometres (about 7,000 football fields) in the German Exclusive Economic Zone bordering Danish territorial waters, and it has an installed capacity of 288 MW.
