NEW YORK, US — The HVDC system should enable the low-loss transport of the generated green energy from the wind farm to the mainland.

Siemens Energy have recently announced that they have been awarded their first offshore grid connection project in the United States. In a consortium with Aker Solutions, the company will be supplying the HVDC transmission system that should bring green energy from New York’s first utility-scale offshore wind project, Sunrise Wind, to the mainland.

According to the company this will be the first offshore wind project in the U.S. to use HVDC technology. The development of the approximately 924 megawatts wind farm is a joint venture between Danish clean energy company Ørsted and US-based energy provider Eversource. Located about 50 kilometres (30 miles) east of Long Island, Sunrise Wind should in future supply nearly 600,000 homes in New York State with green energy and help support the state’s attempt to meet its goal of 100% clean electricity by 2040. 

“To date, we have connected the offshore grid to the mainland 21 times, bringing more than 12 gigawatts of wind power to households in Europe. The fact that we are now able to proceed with our very first offshore HVDC grid connection project in the United States makes us proud,” said Tim Holt, member of the Executive Board at Siemens Energy. “Carbon-neutrality goals will not be met without wide-scale deployment of renewable energy projects like Sunrise Wind. There will be many more wind projects like this in the U.S. and we are happy to do our part to help provide the country with sustainable power.”

Siemens Energy have said that they will deliver the HVDC system on a turnkey basis and provide onshore civil work in partnership with local companies.

Sunrise Wind will support the establishment of an enduring offshore wind supply chain in New York State. The onshore installation of the project’s converter station will be carried out by local companies. The final deliveries are scheduled for the second half of 2025.
