In the first half of 2017, the wind energy transferred by the transmission system operator TenneT from the North Sea to the shore rose to 7.77 terawatt hours (TWh)). In a half-year comparison, the result of the first half of 2017 exceeded that of the first half of 2016 (5.18 TWh) by 50%, which at the same time corresponds to the 72% of total output for the year 2016 (10.83 TWh).
In total, TenneT has nine offshore grid connection systems with a joint 5,221MW capacity for transmitting offshore wind energy to the power grid. TenneT will complete three further grid connection systems by the end of 2019, which will make available a transmission capacity of 7,132MW from the North Sea. There are plans for four more connections by 2025, which will increase North Sea transmission capacity to over 10,000MW.
