Wind Turbine Technology Assessment

Wind Turbine Technology Assessment

Client: Confidential

Completion Date: 2011

Burns & McDonnell performed a due diligence review of the Siemens SWT-3.0-101, a direct-drive wind turbine generator that utilizes a permanent magnet generator. The study was performed on behalf of a confidential client for consideration at two proposed wind farms. Combined, these projects represented the largest prospective order ever received by Siemens for the SWT-3.0-101.

  • Detailed component review
  • Corporate due diligence
  • Commercial risk review
  • Performance review

Burns & McDonnell was retained by a confidential client to provide professional engineering services in the comprehensive independent evaluation of the SWT-3.0-101 direct-drive wind turbine. At the time of the evaluation, no SWT-3.0-101 turbines were commercially operational anywhere in the world, and the projects under consideration represented the largest potential order ever received by Siemens for this machine.

Burns & McDonnell's services included a corporate review of Siemens and its affiliates, including:

  • The wind turbine generator supply chain, quality assurance and control programs
  • Projected orders and lead times for the SWT-3.0-101
  • Detailed history on permanent magnet generator and direct-drive technologies, including a review of worldwide commercial installations of these technologies
  • Detailed review of every major turbine component, including supply chain, known component issues and remediation, testing practices, and certification status
  • Review of turbine performance characteristics including availability, power curve, noise/sound levels, grid compliance, and O&M
  • A comprehensive risk review, encompassing both technical and commercial risk associated with the deployment of a newly released wind turbine generator
  • Burns & McDonnell was the first company in the world to complete an independent technical review of the SWT-3.0-101.
  • Evaluation included site visits to the Siemens blade production facility in Fort Madison, Iowa, and Siemens' headquarters in Brande, Denmark, including interviews with turbine design team and visit to prototype machine in Denmark.
  • Detailed investigation of every major turbine component, including supply chain, known issues and remediation, component testing and certification.
  • Detailed evaluation of expected turbine performance, including availability, power curve, power quality, noise, grid compliance, and operations and maintenance.
  • Detailed risk review associated with deployment of newly-released WTG, encompassing both commercial and technical risk.
