  • Date:

    To be determined

  • Language:


Industry standards and turbine supply contracts provide guidance to perform these verifications but with the potential for wide ranges of uncertainty. This course will cover step by step the process for power performance verification with a focus on reducing uncertainty through the application of best practices.

Additional information: 
The course will explain the principles, process and value of power performance verification. From turbine supply contract negotiation through completion of power performance verification, there are many opportunities to reduce the risk associated with wind turbine performance. Trends will be presented and guidance provided for what to expect at all stages including:

  • Contract negotiation
  • Site evaluation
  • Measurement system design
  • Data processing and interpretation - including case studies
  • Documentation of results
Best practices will be discussed to minimize the risk associated with each stage. Primarily, the uncertainty is a function of the wind speed measurement uncertainty which comprises a handful of components with inputs at each of the above stages. Applying best practices in the design and approach to the wind speed measurement can reduce uncertainty and thereby increase the value of the verification and the value of the power curve warranty.

The course allows attendees to benefit from DNV GL’s extensive experience performing power performance verifications across the globe.

On completion, delegates should understand the value of power performance verification, how the process works and how to minimize the risk. Specifically: how to set the stage during contract negotiation for a successful campaign; what factors most influence the wind speed measurement and how to design for the lowest uncertainty; how the results can be interpreted and leveraged.
