Web site: Task 27 Small Wind Turbine Labeling

The entire wind energy sector should support the labeling initiative to reduce the risk of accidents with small wind turbines and to minimize deceptive investments in less than optimum equipment. The primary objective of this new task is to give incentives to this industrial sector to improve the technical reliability, and therefore the performance, of small wind turbines. The intention is to define a globally standardized product label for small wind turbines and minimum requirements for a testing process that would allow a label to be placed on products. This would give customers and governments minimum assurances regarding the safety and performance of small wind turbines. Common methodologies to test equipment and test results displayed in a form understood by consumers will increase the maturity of the small-scale wind power sector. In addition, consumer quality labels will benefit manufacturers of high-quality small wind turbines, that compete in a marketplace with outdated or untested technologies. But mostly, the outcome of this task will benefit potential buyers and installers of small wind turbines and the official energy entities that give permits to connect them to the electric grid.

This task, approved in April 2008, will develop and deploy a system of quality labeling for consumers of small wind turbines. The task will also contribute to and use an IEA Wind Recommended Practice for labeling small wind turbines. For anyone interested in buying a small wind turbine, this work will also provide information such as recommended methodologies and independent test reports on power performance curves, acoustic noise emissions, strength and safety, and duration tests. The actual testing of the wind turbines is beyond the scope of Task 27. Reliable third-party testers such as national laboratories, universities, and certification entities already exist. The Operating Agent of this task will direct small wind turbine manufacturers to these testers in order to get a label for their products.

The task’s primary goals are to
1) build bridges between small wind turbine manufacturers and third-party testers and
2) to provide private companies with a commonly accepted testing methodology (IEA Wind Small Wind Turbine Recommended Practice).

To accomplish these outcomes, several goals must be met.

• To build up a critical mass of involvement the task will include government agencies, wind turbine manufacturers, and third-party testers (primarily universities, national laboratories and institutes, and companies having considerable experience in testing wind power devices) to develop methodologies for testing and presenting results and for labeling classification. This critical mass should provide the necessary basis for development and wide use of the IEA Wind Recommended Practices for the small-scale wind power sector.

• To test methodologies and labels on several small wind turbines and provide feedback to entities that are working to update methodologies in this area.

• Strongly increase consumer and official entities awareness.

The main deliverables of this new task are a system of quality labels for small wind turbines and an IEA Wind Small Wind Turbine Recommended Practice as a pre-normative international standard for testing and labeling small wind turbines.
