TenneT unveiled its H1 2017 report and now has nine offshore connection grid systems with a joint 5,221 MW capacity in the North Sea for transmitting offshore wind energy to the onshore power grid. By the end of 2019, the company will complete three further grid connection systems and expects to reach a transmission capacity of 7,132 MW. By 2015, this capacity is scheduled to reach 10,000 MW with four more planned connections.
According to the company, the North Sea offshore wind park capacities rose from 3 GW in H1 2016 up to 4.4 GW in June 2017. This expansion requires soaring additional transmission capacities. In the meanwhile, the company reports having transferred approximately 7.77 TWh of wind energy from the North Sea to the German grid in H1 2017, which is already 72% of the total output for the year 2016 (5.18 TWh in H1 2016 and 10.83 TWh in 2016 FY). According to the company, the flow of power from the North Sea has reached 16.5% of the whole wind energy generation in Germany.
TenneT is the Dutch Transmission System operator (TSO) and operates around 40% of the German transmission network.
