Wind Energy – HVDC Substation
Yesterday the Sunrise Wind HVDC substation arrived at the Aker Solutions’ yard at Stord, Norway.
In the coming months the yard team will achieve the platform construction before handing it over to the commissioning group.
Sunrise Wind will be the first offshore wind project in United States to use HVDC Transmission Technology.
The HVDC work is part of Ørsted and Eversource’s overall $400 million investment in New York State to build Sunrise Wind.
HVDC technology offers advantages over AC technology in electricity transmission over long distances. HVDC reduces the number of cables, improves transmission efficiency (e.g., reduces energy lost during transmission) and eliminates the need for additional electrical equipment between offshore and onshore converter terminals.
While HVDC technology is currently used in the U.S., it has not been introduced to offshore wind energy until now.
