TenneT calls for additional offshore wind tender in Germany

July 12 (Renewables Now) - Dutch-German transmission system operator TenneT today urged Germany to optimise the use of transmission capacities via an additional offshore wind tender.

"Approximately 660 megawatts of grid connection capacity will run idle in the foreseeable future in the North Sea," said TenneT's managing director Lex Hartman. "The legislator could allocate these free resources to offshore wind farms via an additional tender to offshore wind farms," Hartman added.

TenneT also called for wind farms in the western German North Sea to be connected to the Dutch grid in the future. A connection to Eemshaven, for instance, would allow 100 km (62 miles) of underground cables, or EUR 200 million (USD 234m) in costs, to be saved in Germany as the grid connection point is located directly on the coast. In this way bottlenecks in the German electricity grid on land will also be circumvented, the company said.

TenneT made the comments as it said it transferred 8.17 TWh of wind power from the German North Sea to the shore in the first half of 2018, an year-on-year increase of 5.15%. The wind farms in the Baltic Sea, which are not within the TenneT grid area, supplied an additional 0.87 TWh, while Germany's total wind generation was about 54 TWh.  

Currently there is 4,716 MW of installed offshore wind capacity in the German North Sea. TenneT has 10 offshore grid connection systems there with a total capacity of 5,332 MW. The company will add three systems by 2023, boosting  transmission capacity to 8,032 MW. There are plans to bring it to almost 11,000 MW by 2027.
