The Ministry of New and Renewable Energy (MNRE) has announced important amendments to its revised guidelines for the installation of prototype wind turbine models. The changes were issued through an Office Memorandum dated June 25, 2026, and revise certain provisions of the guidelines that were originally released on June 12, 2025.
One of the key amendments relates to the power generated by prototype wind turbines. Under the earlier guidelines, a maximum of three wind turbines per prototype model could be installed only for synchronization or commissioning purposes. The revised provision now allows the electricity generated by these prototype models to be sold commercially. Distribution companies (DISCOMs) and other entities can purchase the scheduled power either at a mutually agreed tariff or according to the tariff regulations issued by the Central Electricity Regulatory Commission (CERC) or the respective State Electricity Regulatory Commission (SERC). This change is expected to provide a clear commercial framework for electricity generated during the prototype stage.
The second amendment concerns the installation approval process for prototype wind turbine models. The earlier guidelines stated that serial production and installation of a prototype wind turbine could not begin until the model was included in the Revised List of Models and Manufacturers (RLMM). The updated provision now specifies that installation of prototype wind turbines will not be allowed until the wind turbine model is officially included in the Approved List of Models and Manufacturers (ALMM) for wind turbines. This change aligns the approval process with the government’s updated compliance framework.
Apart from these two amendments, all other provisions of the revised guidelines issued in June 2025 will continue without any changes. The Office Memorandum was issued by Rishikesh Vaishnav, Scientist-C, after receiving approval from the competent authority. The revised guidelines have been circulated to all concerned stakeholders for immediate implementation across the wind energy sector.
