The Siemens Energy and Dragados Offshore consortium snagged a nearly $7.7 billion contract for a trio of projects to transport 6 gigawatts (GW) of wind power in the German North Sea to shore.
The agreement with TenneT, a German-Dutch transmission system operator, was announced this week as the energy industry continues efforts to green up grids globally.
The projects involve supplying high-voltage, direct-current transmission technology for three grid connections—BalWin3, LanWin2 and LanWin4—to transport electricity from offshore wind farms to grid connection points north of Germany.
“In the global race against climate change, grid expansion must be able to keep pace with the accelerated expansion targets for renewable energies,” Tim Holt, member of Siemens’ executive board, said in a news release. “Shorter contracting processes, large-scale tenders and standardization of solutions show how grid operators and manufacturers are already pulling together to get green energy to consumers faster.”
Getting electricity from offshore wind turbines involves converting the energy from alternating current (AC) into direct current (DC) for transport to shore.
While Dragados will construct and install platforms needed for the projects, Siemens will manufacture the main electrical components, including switchgears, transformers and converter technologies.
Here’s a look at some of this week’s other renewable energy news.

Siemens Gamesa Unveils Sustainable Wind Turbine Tower
Siemens Gamesa said April 21 it launched a wind turbine tower, called GreenerTower, which is manufactured with sustainable steel that reduces carbon emissions by at least 63% compared to conventional steel.
“With more than 600 GW of new capacity to be installed worldwide in the next five years, it is important for the wind industry to reduce its carbon footprint,” Maximilian Schnippering, head of sustainability for Siemens Gamesa, said in a statement. “Our project to address emissions with greener steel is one such solution.”
The company is using a qualification process to verify that no more than 0.7 tons of CO2-equivalent emissions are permitted per ton of steel. The first qualifying supplier is German steel manufacturing company Salzgitter AG.
“The process to produce greener steel entails increased use of scrap steel, less energy-intensive steel manufacturing processes and an increased use of renewable energy sources,” Siemens Gamesa said in a news release. “As one of the measures to decarbonize steel production, for example, the electric arc furnace will be fed with green electricity from offshore wind projects.”
RWE and Siemens Gamesa plan to introduce 36 GreenerTowers at the Thor wind power project offshore Denmark, where 36 of the sustainable towers will be installed, Siemens Gamesa said.
Siemens Gamesa said the CO2-reduced tower will be available for onshore and offshore wind projects in 2024.
