MNRE Proposes Key Amendments To RLMM Procedure For Wind Turbines, Seeks Stakeholder Feedback

Posted On - 16 May, 2025 • By - King Stubb & Kasiva

Introduction

Aiming to simplify testing, certification, and grid synchronizing procedures, the Ministry of New and Renewable Energy (MNRE) has released draft revised rules for the installation of prototype wind turbine models.[1] Seeking to replace current rules released in 2012 and 2016, these amendments center on improving the quality and dependability of wind energy technologies in India. Within three weeks, the ministry has invited stakeholder comments on the suggested changes, so indicating a drive to match India’s wind energy sector with world standards and so promote innovation.

Explanation (Key Points)

  1. Stricter Certification and Validity Requirements
    • Prototype wind turbines must undergo type testing and certification by internationally accredited bodies adhering to IECRE OD 501 and IS/IEC 61400-22:2010 standards.
    • Prototype certificates will have a maximum validity of three years, with extensions contingent on compliance with IECRE guidelines and submission of revised documentation to the National Institute of Wind Energy (NIWE).
    • Manufacturers must submit annual progress reports from certification bodies to NIWE, ensuring transparency in testing and maintenance.
  2. Operational Deadlines and Compliance
    • Prototype turbines must be commissioned within 18 months of receiving NIWE’s recommendation letter.
    • Type certification must be obtained within three years, failing which installed prototypes will be disconnected and removed at the manufacturer’s expense.
    • Post-commissioning, grid synchronization reports from state utilities must be submitted to NIWE immediately.
  3. Ownership and Commercialization Restrictions
    • Prototype turbines cannot be sold until the model is included in the Revised List of Models and Manufacturers (RLMM).
    • Serial production of prototypes is prohibited until RLMM approval, ensuring rigorous evaluation before market entry.
  4. Quality Control and Component Standards
    • Only new, unused components may be used in prototypes, barring second-hand parts. Modifications to existing prototypes require NIWE approval and updated certification.
    • Manufacturers must submit an indemnity bond to state utilities and NIWE, pledging compliance with guidelines.
  5. Role of NIWE
    • NIWE will oversee implementation, requiring manufacturers to submit detailed documentation for prototype approvals. Non-compliance may lead to revocation of permissions for safety reasons.

Conclusion

The suggested changes highlight MNRE’s dedication to advancing India’s wind energy industry by means of strict quality control and conformity with international certification criteria. The rules seek to promote innovation by requiring strict testing schedules and ownership safeguards, so guaranteeing grid stability and consumer safety. Finalizing these changes will depend much on the comments of stakeholders, due by 30 April 2025 (three weeks from the circular’s 9 April issuing). Once put into effect, the updated RLMM policies could greatly improve India’s competitiveness in the world wind energy market.
