Wind energy – U.S.A.
Siemens Energy and Aker Solutions will supply the high-voltage direct current (HVDC) transmission system for the 924-MW Sunrise Wind offshore wind project in the US.
The project is being developed by a joint venture between Ørsted and New England utility Eversource Energy. It is New York’s first utility-scale offshore wind project and will be capable of powering almost 600,000 homes in the state.
Siemens Energy said it will provide the HVDC system on a turnkey basis, as well as onshore civil work in partnership with local companies. The HVDC system consists of two converter stations; the offshore converter station will collect the 66 kilovolts alternating current power generated by the wind turbines through an inter-array cable system and transform it to 320 kV DC for transmission through a 160 km export cable to the onshore converter station at Holbrook on Long Island.
The onshore station will convert the power back to AC to feed it into the distribution grid.
According to the announcement, Aker Solutions will be in charge of the platform composed of a steel jacket substructure and a topside platform deck holding the electrical equipment.
The final deliveries are planned for the second half of 2025, Siemens Energy said.
