The 400MW Borkum wind farm, located around 45 kilometres north of the Borkum coast, employs 80 wind turbines that are to be installed at water depths of 25 to 35 metres in two expansion stages.
The Borkum wind farm is being constructed by Trianel in collaboration with 33 municipal participators from Germany, Austria and Switzerland, making it the first municipal offshore wind farm in the North Sea.
Following the completion of the first stage, the wind farm is expected to deliver about 800 million KWh of energy, enough to power 200,000 households annually.
Both stages of the expansion are accounted to be around €1.6bn and is expected to become commercially operational in late 2013.
Alstom’s offshore substation platform links the turbines to the onshore power grid at the connection point. The complete scope of the contract comprises a F351 gas-insulated substation and two 225 MVAr transformers for the platform.
Alstom’s Dresden site (Saxony) was in charge of project management, while teams at Mönchengladbach (North Rhine-Westphalia) delivered the transformers. WeserWind Offshore Construction GmbH in Bremerhaven produced the steel structure for the platform.
