Global Tech I: construction of North Sea wind farm completed

Offshore power station erected with 80 turbines of the five megawatt class. Connection to the TenneT converter station BorWin beta to follow soon.

100 kilometres from the German coast, the offshore wind power station now stands with 80 turbines of the five megawatt class (AREVA Wind M5000-116) and the farm’s own transformer station. Before the start of operations, an underwater robot will be checking that the farm’s 120 kilometres of internal cables lay correctly and at the right depth in their seabed trenches. Arjen Schampers, Technical Managing Director of Global Tech I Offshore Wind GmbH with responsibility for the wind farm’s construction: “We are proud of having constructed a 400-megawatt wind farm at sea in water 40 metres deep. Building the wind farm was a superb example of teamwork, resulting in a technical masterpiece.” Construction was completed within its cost parameters.

Green energy for 445,000 households

Around 100 people are working directly for the project company Global Tech I Offshore Wind GmbH, which has planned and constructed the wind farm since early 2010. The Global Tech I offshore substation platform is manned by up to 38 persons around the clock to guarantee smooth operations. The technical design of the transformer substation and the internal cabling has been configured with redundancy. Thus, a reliable supply of electrical energy for 445,000 households can be guaranteed. The operational control station of the wind farm is located at the company headquarters in Hamburg.

Early connection to the converter station BorWin beta

Transmission grid operator TenneT wants to connect Global Tech I in early September to BorWin beta, the TenneT offshore converter station. The early connection will supply the turbines with energy needed for their operation. TenneT wants to commence with test operation of the grid connection and the interplay of the overall system of connection and wind farm during the fourth quarter this year. During the test phase, the wind turbines will contribute small amounts of electricity to the grid. The regular grid connection is expected to be available in early 2015.
