- The company has secured what it says is the most extensive offshore grid connection in its history.
- The firm will supply two offshore wind power converter platforms.
Siemens Energy has announced its newest and largest win in the company’s history. It is said to have won the largest offshore grid connection order.
The order, made by Amprion Offshore, will see Siemens Energy supply two offshore wind power converter platforms at sea, DolWin4 and BorWin4, and two associated stations on land.
According to the announcement, the platforms convert alternating current, which wind turbines produce, into direct current. The direct current is then transferred to a high-voltage direct current transmission cable (HVDC cable) for transport. A second converter station on land then converts the electricity back into alternating current.
“Only in this way can the large amounts of energy cover the distance of around 215 km (DolWin4) and 280 km (BorWin4) without significant losses (low-loss). Furthermore, the two connections will be installed in parallel and are scheduled to begin operating in 2028. BorWin4 would thus even be connected to the grid one year earlier than originally planned,” Siemens Energy said.
