Encompassing three offshore wind power projects, the signed conditional contract is the largest US offshore wind power order to date. It encompasses the supply, delivery, and installation of SG 8.0-167 DD wind turbines including service agreements in federal waters off the northeast coast of the US. All deliveries are subject to Ørsted and Eversource’s final investment decision.
The contract includes delivery of offshore wind turbines totaling 880 MW for the Sunrise Wind project, which will be the company’s largest offshore wind project in the US. SG 8.0-167 DD offshore wind turbines will be utilized at the project in federal waters about 30 miles off Montauk Point at the the eastern tip of Long Island, New York. A service agreement is included.
The Sunrise Wind project is expected to be operational in 2024.
The 704 MW Revolution Wind offshore project will be located 15 miles off the coast of Rhode Island. The project will utilize SG 8.0-167 DD wind turbines and is expected to be online by 2023. Once operational, Revolution Wind will deliver power to Rhode Island and Connecticut.
Additionally, SGRE was conditionally awarded the contract to deliver SG 8.0-167 DD offshore wind turbines for the 130 MW South Fork offshore wind power project. Located 35 miles off the coast of Long Island, it is expected to be operational by the end of 2022 and will deliver power to the Long Island Power Authority.
“We had already secured a US construction pipeline of almost one gigawatt before the end of 2018 and have been looking into further growth in the US offshore wind market. We saw an opportunity to secure a bigger turbine volume early in order to gain economies of scale, and Siemens Gamesa was able to provide an attractive offering for this large volume,” said Anders Lindberg, Executive Vice President, EPC, at Ørsted.
The SG 8.0-167 DD wind turbine has a rated capacity of 8.0 MW, and a rotor with a 167-meter diameter. It has a swept area of 21,900 m2, and uses the SGRE B81 blades, each measuring 81.4 meters. By 2020, more than 1,000 SGRE Direct Drive offshore wind turbines will be installed globally.
The U.S. variant of the SG 8.0-167 DD is designed for IEC class S, considering tropical storm conditions (T-Class for the Rotor Nacelle Assembly). The T-class type certification for the Rotor Nacelle Assembly will be achieved by December 2020, where the product will be certified to handle extreme wind speeds in hurricane conditions in accordance with IEC 61400-1 edition 4. Furthermore, electrical systems and components will be adapted to 60Hz operation.
