400MW Global Tech 1 set to go

Construction of the 400MW Global Tech 1 (GT1) wind farm off Germany is now complete, with infield cabling being checked before the development's 80 turbines begin flowing electricity to the BorWin Beta converter station.

The wind power project, built around 5MW Areva M5000-116s installed in some 40 metres of water 100km offshore, is expected to be brought online "within its cost parameters", according to developer GT1 Offshore Wind, a consortium made up of Stadtwerke München, HSE Darmstadt, Axpo International, Esportes Offshore Beteiligungs, Norderland Projekt and Windreich.

"We have worked day and night in all winds and weathers and proven we can construct with precision a 400MW wind farm at sea," states GT1 technical managing director Arjen Schampers.

"Manufacturing, logistics and installation must proceed hand in hand. All in all, building the wind farm was a superb example of teamwork, resulting in a technical masterpiece."

Cabling work at the wind farm is now being finished, with an underwater robot surveying the development's 120km of inter-array lines.

The 800MW BorWin Beta converter station, built by contractors Siemens, Nordic Yards and Prysmian for Dutch-German transmission system operator TenneT, is slated to be switched on "in early September".

At full production the wind farm will supply energy to some 445,000 households.

TenneT aims to start test operations of the grid connection during the fourth quarter of this year, with GT1 producing to the onshore network from early 2015.
