Alstom Grid has successfully delivered the offshore substation platform for the Trianel wind farm Borkum in the German North Sea.
Borkum is a 56 km² wind farm, located around 45 km north of the Borkum coast. The wind farm consists of 80 wind turbines with a total power of 400 MW in two expansion stages. After the completion of the first expansion stage with a performance of 200 MW, it will generate up to 800 GWh/year, enough to supply almost 200,000 households with power. The Borkum wind farm is being constructed by Trianel in association with 33 municipal participators from Germany, Austria and Switzerland, making it the first municipal offshore wind farm in the North Sea. The total investment sum for both expansion stages of the wind farm is around €1.6bn. It is scheduled to enter commercial operation in late 2013.
Alstom’s offshore substation platform connects the turbines to the onshore power grid at the connection point. The full scope of the contract includes a F351 gas-insulated substation and two 225 MVAr transformers for the platform.
