In future, a single grid connection will transport up to two gigawatts (GW) of offshore wind power to the onshore power grid, This is made possible by converter systems provided by Siemens Energy and Spanish company Dragados Offshore.

The German transmission system operator Amprion has awarded the world's first order for two of these systems to the consortium.

In total, up to four gigawatts of green electricity from several offshore wind farms in the German North Sea can be transported to shore – enough electricity to meet the needs of about four million people.

The contract for the consortium is worth a total of more than €4 billion including maintenance for ten years. For Siemens Energy it is the largest offshore grid connection order the company has received to date.

"The wind energy industry has repeatedly achieved outstanding technological advances in recent years, be it in the performance of wind turbines or grid connections,” said Tim Holt, member of the Managing Board of Siemens Energy. “The two-gigawatt system fits in seamlessly here, making the transmission of green power more efficient and creating standardization where individual designs were previously necessary. Developments in the industry have taken time, which must no longer be wasted against the backdrop of ambitious offshore expansion targets and the drastic consequences of climate change," added Holt.

Siemens Energy's scope of supply consists of two converter platforms at sea and two associated stations on land. The wind turbines generate alternating current and feed it into the converter platforms, which convert the alternating current into a direct current.

Only in this way can large amounts of energy travel the long distance of around 390 kilometers (242 miles) each to the two converter stations on land via a direct current cable.

The converter stations on land are being built near Wehrendorf in Lower Saxony and Westerkappeln in northern North Rhine-Westphalia.
