Ørsted and Eversource have awarded Siemens Energy a contract to supply a transmission system for their 924 MW Sunrise Wind offshore wind farm that will power New York State.

The two companies said the deal would make them the first offshore wind companies to use high voltage direct current (HVDC) technology as part of a US offshore wind farm, deploying the efficient transmission system for the Sunrise. Wind of New York. It is also the first offshore grid connection project in the United States for Siemens Energy, which will supply the HVDC system in consortium with Aker Solutions.

HVDC technology offers advantages over AC technology in the transmission of electricity over long distances. HVDC reduces the number of cables, improves transmission efficiency (for example, reduces energy lost during transmission) and eliminates the need for additional electrical equipment between offshore and onshore conversion terminals. Although HVDC technology is currently in use in the United States, it has not been introduced into offshore wind power until now.

“Sunrise Wind will have an approximately 100 mile submarine transmission cable connecting the offshore power generation to the grid connection in Holbrook, New York. Due to its capacity of 924 megawatts and its distance to the grid, Sunrise Wind is well suited to deploy this technology and leverage its benefits, ensuring that as much clean energy as possible reaches residents of New York, â€Ã˜rsted said.

“As a global leader in offshore wind energy, we are helping to advance the US industry to help meet the Biden administration’s goal of 30 gigawatts by 2030,” said David hardy, CEO of Ørsted Offshore North America. “This includes building the supply chain and manufacturing base, as well as bringing advanced technology to the United States that will further improve driveline efficiency and build workforce capabilities. work for this growing American industry. â€

The HVDC work is part of Ørsted and Eversource’s overall $ 400 million investment in New York State to build Sunrise Wind. Parts of the HVDC work, including onshore converter stations, will be carried out by local companies, Ørsted said.

“This will help create jobs and provide additional offshore wind experience to the region’s workforce, which can support a growing industry for decades. In total, Sunrise Wind will provide up to 800 direct jobs during construction, as well as up to 100 permanent jobs. maintenance time of the wind farm during operation. In addition, it is estimated that Sunrise Wind will create up to 2,000 indirect jobs, â€added the Danish offshore wind developer.

“Together, we are bringing the most advanced transmission technology available to the service of our Sunrise Wind project,†said Joe Nolan, President and CEO of Eversource Energy. “Using this technology allows us to efficiently deliver a clean offshore wind turbine. It also indicates that the country is ready to integrate large offshore wind farms like Sunrise Wind into the grid system.

The Sunrise Wind site is located more than 30 miles east of Montauk Point and will produce enough electricity to power nearly 600,000 New York homes. It should be operational in 2025.

“To date, we have connected the offshore grid to the continent 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, â€said Tim holt, member of the Siemens Energy board. “Carbon neutrality goals will not be achieved without the large-scale deployment of renewable energy projects like Sunrise Wind. There will be many more wind projects like this in the United States and we are happy to do our part to help provide the country with sustainable energy. “
