Transmission system operator (TSO) Tennet transferred 11.51TWh from the German North Sea between January and June 2020 - up 21.1% year on year.
Meanwhile, 50Hertz transmitted 2.2TWh of wind power from the German Baltic Sea in H1 2020 - up 3.2% from the previous year.
The two TSOs’ figures suggest that offshore wind accounted for 18.5% of total German wind generation in the first half of 2020 (73.7TWh). Tennet reported that onshore wind generated 59.67TWh in the first six months of the year. Provisional figures had initially suggested 75.06TWh of wind power was generated between January and June 2020.
Tennet added that it is working to develop a standardised cable system to use until 2030 - at BalWin 1, BalWin 2 and BalWin 3 in the German North Sea, and at IJmuiden Ver Alpha and Beta in the Dutch North Sea - as well as in future projects with the same power and voltage. This will lower costs, strengthen security of supply and minimise environmental impacts, it explained.
It plans to invest around €20 billion by 2030 in connecting German and Dutch offshore wind.
The TSO can currently connect 7,132MW off Germany and will reach 1.4GW off the Netherlands in mid-August. By 2030, it projects it will be able to connect around 17GW off Germany, and 9.6GW off the Netherlands.
