  • Multi-brand wind service offering will draw upon complementary strengths and experience of both companies

  • Customers with multiple turbine brands to benefit from an array of customized solutions for their entire fleet

Siemens and Duke Energy Renewable Services today announced an agreement to offer North American wind farm owners operations and maintenance services for multiple brands of wind turbines. Siemens and Duke Energy will combine their complementary service capabilities on Siemens and other OEM equipment.

The agreement offers a one-stop shop for customers who are managing multiple brands of wind turbines in their fleet, helping them stay competitive and derive maximum value from their wind energy assets. 

The cooperation between one of the world’s top turbine manufacturers alongside one of North America’s leading wind energy owner-operators with vast experience working on non-Siemens turbines, means the market now has a new and powerful choice. Customers may turn to either Siemens or Duke Energy Renewable Services when it comes to serving their multiple-brand O&M needs.

“This services cooperation between Siemens and Duke Energy Renewable Services combines the complementary strengths and experience of two key wind energy companies in the North American market,” said Darnell Walker, head of Siemens Power Generation Services, Wind Power and Renewables, Americas region. “This is a powerful duo and by working together we can offer our customers new and expanded service product offerings and capabilities.”

“We are pleased to be working with Siemens to offer flexible, effective and reliable O&M services for wind asset owners,” said Jeff Wehner, vice president of Duke Energy Renewables Operations. “In addition to our services business for third parties, we are experienced wind energy owners and operators. This perspective and deep industry knowledge drives our efficient, customer-centric approach to our renewable services business.” 

The North American wind energy market, particularly the U.S. market where the industry’s maturation is continuing with nearly 50,000 wind turbines installed, is experiencing changing dynamics. Customers are seeking a single point of contact to provide service and maintenance for a wind project’s entire fleet and flexibility in service contract scope.

Siemens is adapting to this changing environment through innovative solutions, as well as through increased investment in service R&D, a new modular and flexible portfolio and a robust digital services portfolio.

With expertise in a wide range of technology, including eight turbine manufacturers, Duke Energy Renewable Services maximizes wind asset performance and drives revenue. It also offers remote monitoring and asset optimization through its Renewable Control Center.
