Siemens to supply high-voltage equipment for major offshore wind project in the U.S.


• Siemens will provide main equipment for an electrical service platform for wind power project
• Mayflower Wind developing a lease area with capacity of up to 1.6 gigawatts of renewable energy
• Electricity for up to 680,000 U.S. households

Siemens has been awarded an order from Danish customer Semco Maritime to provide the main electrical equipment for the electrical service platform (ESP) of the offshore wind project Mayflower Wind LLC (Mayflower Wind). The project is located in a federal lease area approximately 25 miles south of Nantucket, Massachusetts in the United States, and will have a capacity to generate up to 1.6 gigawatts (GW) of renewable energy. Siemens will supply the components for Semco Maritime by 2022.
Earlier this year, a joint venture between the Danish companies Bladt Industries and Semco Maritime was chosen by end customer Mayflower Wind – a joint venture of Shell & EDP Renewables – to design and construct the electrical service platform of the offshore project Mayflower. Semco Maritime has now awarded Siemens with the contract for the delivery of the high-voltage electrical equipment for the ESP, including three 275 kV / 265 MVAr shunt reactors, a 72 kV HV gas insulated switchgear (GIS), three 275 kV MV GIS systems, integrated conditioning monitoring system and SCADA and protection systems.

“At Semco Maritime, we have for a number of years created a very strong track record to deliver competitive quality projects in electrical infrastructure for offshore wind. We are looking forward to the cooperation with Siemens, who is a competent and reliable partner,” says Carsten Nielsen, Senior Vice President of Renewable Energy at Semco Maritime.
