In terms of the “wind harvest” in the German control area of TSCNET shareholder TenneT, 2018 has been yet another record-breaking year. The result in 2018 exceeded the previous year’s figure by 4.9 percent. The wind energy transmitted from the North Sea by the Dutch-German transmission system operator (TSO) amounted to 16.75TWh in 2018 – a new record. This was made possible by a total transmission capacity of 6,232MW provided by altogether eleven offshore connection systems, which have by now been connected to the onshore grid by TenneT.
That is more than in line with the German political targets. “With this, TenneT has now almost entirely achieved the federal government’s expansion goal of having 6,500MW of offshore wind capacity by 2020,” comments TenneT Managing Director Wilfried Breuer. And what’s more: “Already this year, TenneT will exceed this goal since the completion of BorWin3 in the course of 2019 will put a total of 7,132MW of transmission capacity into operation in the North Sea alone.”
In addition to the company’s infrastructural efforts, TenneT pursues numerous innovative technological approaches. A current example in the offshore sector is the planned 66kV technology, which will be used for the future TenneT offshore connections DolWin5 and BorWin5. 66kV technology can reduce investment and operational costs by millions as it supersedes offshore transformer platforms and significantly reduces the amount of cables required to connect individual turbine systems.
