Issue of Type certificate

The issue of Type certificate to a Wind Turbine Model under the Certification Scheme operated by NIWE is determined by the results of conformity assessment through Evaluation and provided documents are conforms to the requirements specified in the certification scheme and the applicant has fulfilled all other conditions.

Before issuing a certificate the following must be addressed:

  • All evaluation reports shall be prepared and signed by the engineer(s) who have verified the documentation.
  • The signed evaluation reports must be reviewed and signed by another qualified engineer.
  • Certification Engineer, based on the evaluation reports, shall prepare the conformity statements and final evaluation report. Project Leader shall review the conformity statements and the final evaluation report. The final evaluation report concludes the certification process with an appropriate recommendation that a Wind Turbine is ‘recommended’ for certificate, with or without outstanding issues, or ‘not recommended’. The final evaluation report and the conformity statements are approved by the Project Manager.
  • Based on the approval of the final evaluation report and the conformity statements, the certificate shall be prepared Project Leader and reviewed by the Project Manager. The certificate shall be prepared as per the format. The PM/Head and PL shall sign the conformity statements, final evaluation reports and the certificate.
  • Administrative approval of Director General(DG) shall be sought by Head for grant of certificate. A note for approval shall be sent to DG, along with the certificate, the conformity statements and the final evaluation report. Upon approval from DG the project completion report shall be sent to Finance & Administration (F&A) unit. F&A unit shall send an invoice to the client as per the contract.
