Recently the Ministry of New and Renewable Energy has come up with a draft scheme known as “Indian Turbine Certification Scheme,” which incorporates the guidelines for certifying the Turbines in India.
Basics of the Scheme
- The scheme is a compilation of best National and International Standards, Technical Regulations and requirements as issued by the Central Electricity Authority and other international bodies.
- It has also strived to incorporate various best practices from other countries to ensure the quality of the wind energy projects.
- The scheme is mainly focused on assisting and facilitating the following stakeholders:
- Original Equipment Manufacturers (OEMs)
- End Users -Utilities, SNAs, Developers, IPPs, Owners, Authorities, Investors, and Insurers
- Certification Bodies
- esting Laboratories
- IWTCS is approved and issued by the Ministry of New and Renewable Energy (MNRE), Government of India.
- The draft Scheme incorporates the guidelines for the benefit of all the stakeholders from concept to lifetime of a wind turbine, including the followings:
- Indian Type Approved Model (ITAM)
- Indian Type Certification Scheme (ITCS)
- Wind Farm Project Certification Scheme (WFPCS)
- Wind Turbine Safety & Performance Certification Scheme (WTSPCS)
- The guidelines for the recognition of the certification schemes was paramount for the success of quality wind turbines installed in the country.
- The successful evaluation under the recognized schemes resulted in the wind turbines being listed in the Revised List of Models and Manufacturers (RLMM).
- This listing has resulted in stakeholders having confidence in the quality of the wind turbines offered by various manufacturers.
WIND ENERGY IN INDIA
- Wind energy has matured to be the mainstream source of renewable power generation in the country in the past few decades.
- The steady growth of this sector has seen different types of wind turbines with various performance and safety criteria.
- The Indian Government India through various policies and schemes has facilitated the healthy and orderly growth of the wind energy sector.
- Wind sector is growing at a rapid pace with increased utilization of wind energy for fulfilling the energy requirement and power generation, especially in the remote regions.
- The modern wind turbines have higher hub heights, larger rotor diameter, higher capacity and improved Capacity Utilization Factor (CUF) along with technological improvements.
- Under these developments, there is a need for a comprehensive document which provides the complete technical requirements which shall have to be compiled by the wind turbines for the safe and reliable operation by all the stakeholders viz, OEMs, Independent Power Producers (IPPs), wind farm developers, Financial Institutions, Utilities, and others.
- Also, there is a need for technical regulations which shall facilitate common ground for OEMs, Developers, Investors and Financial Institutions for systematic development.
- India’s current target is achieving 5GW of offshore wind capacity by 2022 and 30GW by 2030.
CERTIFICATION OF WIND TURBINES
- Type Certification of wind turbines plays an active role in ensuring that wind turbines in India meet the requirements of requisite IS/IEC/IECRE standards in vogue.
- At the global level, IEC /IECRE Certification schemes for wind turbines are well recognized and widely used, and the IWTCS in its formulation has incorporated the rules and procedures of IS/IEC/IECRE.
- The IWTCS defines certification system guidelines for wind turbines that comprised of Prototype Certification and Type Certification; Project Certification, Failure reporting of installed wind turbines, Safety and Performance assessment and De-commissioning & Safe Disposal of the wind turbine/wind turbine projects installed onshore and offshore.
- The body specifies guidelines for carrying out conformity evaluation of wind turbines and wind farms, concerning specific standards and other technical requirements, relating to safety, reliability, performance, testing, and interaction with electrical power networks.
PURPOSE BEHIND CERTIFICATION
- The primary purpose of this certification is to ensure that the wind turbine is designed, documented and manufactured in conformity with design assumptions, specific standards, and other technical requirements.
- The document is expected to benefit and assist all stakeholder involved in the field. More than 30 companies and consortia have shown interest to build a 1,000MW offshore wind project in India, following NIWE’s invitation for expressions of interest issued earlier this year.
THE ROAD AHEAD
Presently, the ministry has uploaded the draft on its website and invited suggestions from all the concerned stakeholders and the public. As soon as the draft is approved, it will help in realizing the dream of making India self-sufficient in the field of energy. The draft will ensure the implementation of best practices in the field of wind energy to be implemented in the country with their effective and efficient implementation.
