TenneT delivered 7.77 terawatt hours of electricity generated by offshore wind in the North Sea in the first half of 2017, up 50% on the 5.18TWh in the same period last year.
The transmission system operator said the 2017 figure corresponds to 72% of total offshore output in 2016 (10.83TWh).
TenneT said it currently has nine offshore grid connections with combined capacity of 5221MW.
It plans to complete three further grid connections by the end of 2019, bringing available transmission capacity from the North Sea to 7132MW.
The company also has plans for four more connections by 2025, which will increase North Sea transmission capacity to over 10GW.
TenneT management board member Lex Hartman said: “The flow of energy from the North Sea has now reached a significant 16.5% share of overall wind energy generation in Germany and thus represents almost a sixth of the total wind power output.
“At the same time, future costs will decrease for wind farms and connection systems, which points to excellent economic performance in the field of offshore energy. We are also expecting this trend to continue as time progresses.”
