Suzlon Wind Energy, the North American arm of Suzlon Energy, has signed a repeat order with Duke Energy, of Charlotte, North Carolina, to provide 20 units of the S88-2.1MW wind turbines. With this order, the total supply portfolio to Duke Energy increases to 130MW.

According to the company, the project located in Cheyenne, Wyoming, is named the Silver Sage windpower project, and is adjacent to an existing wind farm owned by Duke Energy, also supplied by the Suzlon S88-2.1MW turbine.

The contract will provide turbines for the Silver Sage windpower project, located next to the Happy Jack windpower project, in Cheyenne. In addition to supply, Suzlon will provide operations and maintenance through a five-year service agreement with Duke Energy. Suzlon already has provided 29MW of capacity for the nearby site, and a total of 71MW to all Duke Energy projects, said the company.

Andris Cukurs, CEO of Suzlon Wind Energy, said: Expanding our supply portfolio to Duke demonstrates Suzlon’s ability to provide good products and services to wind energy developers. We have provided customer service, which we believe has given us another opportunity to grow our partnership with Duke.

Duke Energy claims to supply and deliver electricity to approximately 4 million U.S. customers in its regulated jurisdictions. The company has approximately 35,000 megawatts of electric generating capacity in the Midwest and the Carolinas, and natural gas distribution services in Ohio and Kentucky.
