Kick off for German grid growth
380kV line will help bring offshore wind power to consumers
Transmission system operator TenneT has started construction of its 380kV power line connecting Meppen in North-Rhine Westphalia with the grid hub at Dörpen West, Lower Saxony.
The 30km connection is needed to add a growing amount of electricity generated by offshore wind farms to the onshore wind power produced in the region, TenneT said.
The 900MW DolWin3 grid connection system will be fully operational in late 2018, connecting Orsted’s 450MW Borkum Riffgrund 2 and the 396MW Merkur offshore wind farms to the onshore converter station in Dörpen West.
The new AC power line features a 3.1km underground section, the first of its kind in Germany.
TenneT expects the power line to be completed within 18 to 24 months.
“This is the start of construction of an important connection between the offshore wind farms in the North of Germany and the high-demand West of the country,” said TenneT executive Lex Hartman.
Last year, policymakers in Berlin restricted the expansion of offshore wind farms in the German North Sea in the early 2020s because of slow progress on grid expansion in Lower Saxony.
