Siemens awarded largest US offshore wind power order

24 July 2019

Siemens Gamesa Renewable Energy has received, conditionally, a record order for 1714 MW from Ørsted and Eversource. 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 northeastern coast of the USA. All deliveries are subject to Ørsted and Eversource’s final investment decision.

The first of the three projects is Sunrise Wind, 880 MW. Ørsted and Eversource were awarded this capacity by New York State. SG 8.0-167 DD offshore wind turbines will be utilised at the project in federal waters about 50 km off Montauk Point in New York. The array is expected to be operational in 2024.

The 704 MW Revolution Wind offshore project will be located 24 km the coast of Rhode Island and will utilise SG 8.0-167 DD wind turbines. It is expected to be online by 2023. Once operational, Revolution Wind will deliver power to Rhode Island and Connecticut.

SGRE was also been awarded the conditional contract to deliver SG 8.0-167 DD offshore wind turbines for the 130 MW South Fork project. Located 56 km off Long Island, NY, it is expected to be operational by the end of 2022 and will deliver power to the Long Island Power Authority.

The SG 8.0-167 DD WTG has a rated capacity of 8.0 MW and a rotor with a 167-metre diameter. It has a swept area of 21 900 sq m, and uses the SGRE B81 blades, each measuring 81.4 metres. By 2020, more than 1000 SGRE Direct Drive offshore wind turbines will have been installed globally.

The US 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.
