In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This qualification does not replace any other qualification and is not replaced by any other qualification. 

The purpose of this qualification is to prepare a learner to operate as a Wind Turbine Service Technician.

A Wind Turbine Service Technician plans, prepares and conducts installation, maintenance and component assembly for wind turbine processes, systems, facilities and equipment.

A qualified learner will be able to:
  • Prepare and plan for installation of components.
  • Inspect, diagnose malfunctioning and conduct maintenance, replacement and repair of wind turbine components.
  • Assemble and install component parts and/or equipment.

    A consortium of sector organisations, including Green Cape, Centre for Renewable and Sustainable Energy Studies and South African Wind Energy Association, conducted and supported earlier studies by identifying the need for specific training for Wind Turbine Service Technicians in South Africa.

    The Department of Higher Education and Training (DHET) allocated funds for the establishment (design, erection and commissioning) of the South African Renewable Energies Technology Centre (SARETEC) at the Cape Peninsula University of Technology (CPUT) to focus on training of Wind Turbine Service Technicians. This initiative is supported by the National Skills Fund (NSF), South Africa's National Energy Development Institute (SANEDI), DHET; Department of Education (DoE), GIZ, CIM, GREEN CAPE, BAVARIA and ESKOM. Erection of wind turbine parks has commenced in the Eastern and Western Cape.

    This qualification will draw learners that are qualified in disciplines such as Electrician, Fitter/Turner, Millwright and Mechatronics, and various other equivalent national certificates from the Technical Vocational Education and Training colleges (TVET). The incumbents will receive additional training in operation and maintenance of wind turbines. Learners will perform a variety of (operational and maintenance) functions that are important to sustain the capital investment in this sector.

    The wind energy will provide an additional source of alternative energy and assist the South African economy to comply with various international protocols aimed at reducing carbon emissions and promoting sustainable environment practices. The current concession contracts for installation of wind turbines in the three Cape provinces are estimated to have generated many additional jobs for Wind Turbine Service Technicians. Currently, almost all the components required for erection of wind turbines are imported, but the potential exists for immediate development of component manufacturers and other services around targeted areas of Western, Northern and Eastern Cape. 

    Recognition of Prior Learning (RPL):
    RPL for access to the external integrated summative assessment: Accredited providers and approved workplaces must apply the internal assessment criteria specified in the related Curriculum document to establish and confirm prior learning. Accredited providers and workplaces must confirm prior learning by issuing a Statement of Results or certifying a Work Experience Record.

    RPL for access to the qualification: Accredited providers and approved workplaces may recognise prior learning against the relevant entry requirements.

    Integrated Assessment:
    Integrated Formative Assessment:
    The skills development provider will use the Curriculum to guide them on the stipulated internal assessment criteria and weighting. They will also apply the scope of practical skills and applied knowledge as stipulated by the internal assessment criteria. This formative assessment leads to entrance into the integrated external summative assessment.

    Integrated Summative Assessment:
    An external integrated summative assessment, conducted through the relevant Quality Council for Trades and Occupations (QCTO) Assessment Quality Partner, is required for the issuing of this qualification. The external integrated summative assessment will focus on the Exit Level Outcomes and Associated Assessment Criteria. 

    The comparability study was undertaken to examine whether the Wind Turbine Service Technician qualification is comparable to international best standards in terms of the competencies that Wind Turbine Technicians are expected to attain upon completion of a qualification.

    United States of America:
    The National Center for Construction Education and Research (NCCER) is a not-for-profit education foundation created in 1996. It was developed with the support of more than 125 construction CEOs and various association and academic leaders who united to revolutionise training for the construction industry. Sharing the common goal of developing a safe and productive workforce, these companies created standardised training and credential programmes for the industry. The NCCER in collaboration with the American Wind Energy Association (AWEA) have developed a Core Skill Set for Wind Turbine Service Technicians.

    The core skill set is as follows:
  • Demonstrate the ability to inspect the required personal protective equipment prior to use.
  • Properly and safely ascend and descend a 30-foot tower or comparable structure.
  • Under instructor supervision, measure the voltage from line to neutral and neutral to ground.
  • The ability to use an ohmmeter to measure the value of various resistors.
  • Prepare and terminate various low-voltage conductors and cables.
  • Select the appropriate conductor based on the ampacity, insulation type, and temperature rating using the National Electrical Code (NEC) tables.
  • Interpret hydraulic schematics and symbols; check hydraulic fluid levels; inspect and replace hydraulic system strainers and filters and charge an accumulator.
  • Perform necessary record keeping.

    This qualification has ensured that the international standard compiled for Wind Turbine Technicians' competencies has been met. In addition this qualification also enables learners to to be able to identify and address malfunctioning components of a wind turbine plant as well as to be able to operate and maintain a wind turbine and its subcomponents.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
