India has taken a significant step to enhance the efficiency of its wind power generation with the introduction of the ‘National Repowering and Life Extension Policy for Wind Power Projects – 2023’. The initiative aims to rejuvenate the country’s aging wind turbines, many of which were installed before 2000.
The policy allows for the repowering or replacement of older turbines with more efficient ones, even before reaching their original design life, through modifications in components such as gearbox, blades, generator, and controller.
As of October 2023, India’s wind power capacity has grown from 21.1 GW in March 2014 to 44.29 GW. However, the outdated technology of older turbines has prompted the ministry of new and renewable energy to revise its 2016 policy, emphasising the repowering or refurbishment of these installations.
Under the new policy, wind project developers can replace older turbines with modern and efficient ones, even before the end of their original design life. The policy also allows for the refurbishment of turbines to extend their operational life, provided they meet necessary safety and performance standards.
The National Institute of Wind Energy estimates that India has a repowering potential of about 25.406 GW for turbines below two MW capacity. Tamil Nadu is identified as having significant potential, with a projected capacity of 7386.5 MW. Eligibility criteria for turbines to undergo repowering or refurbishment include non-compliance with quality control orders, completion of design life, and a rated capacity below 2 MW.
As reported by ETEnergyworld.com, to facilitate policy implementation, the involvement of state nodal agencies and a central nodal agency, appointed by the government, is envisioned. The policy distinguishes between standalone projects, owned by a single entity, and aggregation projects, owned by multiple owners with shared infrastructure.
