The one day short course allows attendees to benefit from DNV GL’s extensive experience in power performance measurements by having a focused look at the relevant changes and recommendations included in Edition 2 (2017) of IEC 61400-12-1.
Particular attention will be paid to site calibration requirements, new analysis methods (e.g. shear and veer corrections) and uncertainties. Breakfast and lunch are included with the course.

Additional information
Expectations for power performance verification are defined and negotiated before financial close of a project in order to minimize financial risk. Performance verification procedures and power curve warranties are defined in the turbine supply contracts. After wind farm commissioning, the verification test is used to demonstrate that the turbine’s performance is within the acceptance level and to quantify the uncertainties. The test can also be carried out during the wind farm operation in order to follow and quantify the performance of the wind turbines.  

On completion of this course, delegates should understand the key changes in Edition 2 and their potential impacts for power performance warranties and analysis. 

Who should attend?
Developers, operators, turbine manufacturers, lenders and other professionals involved with power curve warranty negotiations and measurement campaigns who wish to benefit from DNV GL’s technical knowledge and expertise. Attendees with a basic or more advanced understanding of IEC 61400-12-1 Edition 1 will benefit most from the course.
