Adani New Industries Limited (ANIL) is set to manufacture India’s longest onshore wind turbine blades, measuring 91.2 metres, at its Mundra facility in Gujarat. With this move, the company positions itself at the forefront of India’s transition toward higher-capacity wind turbines and enhanced energy generation from low- and medium-wind sites.
Technological Leap in Wind Blade Manufacturing
Currently, the Mundra plant produces wind turbine blades of 78.6 metres and 80.5 metres. However, the new 91.2-metre blade marks a significant advancement in composite materials engineering, aerodynamic design, and precision manufacturing. The company has already installed the first set of these blades on a new turbine platform. It will commence serial production within this calendar year, signalling a rapid commercial rollout.
Larger Rotor, Higher Energy Yield
Blade length directly impacts rotor diameter and, in turn, energy capture. A 91.2-metre blade enables a rotor diameter of nearly 185 metres, sweeping approximately 26,600 square metres. As a result, the turbine can harness more kinetic energy from the wind. The expanded swept area improves capacity utilisation and increases overall power output, making projects more economically viable.
Unlocking Low and Medium Wind Potential in India
The development is particularly significant for India, where a large share of untapped wind potential exists in low- and medium-wind regimes. Turbines rated above 5 MW, supported by longer blades and higher hub heights, can now make such sites commercially attractive. Consequently, the shift toward larger turbines reflects both India’s geographical realities and ongoing technological progress in the wind energy sector.
Scaling Manufacturing Capacity at Mundra
Currently, the Mundra facility has a blade manufacturing capacity of 2.25 GW per annum, equivalent to roughly 450 blade sets. Going forward, ANIL plans to scale this capacity to 5 GW in phases, with a long-term target of reaching 10 GW. The company has earmarked investments of up to ₹3,000 crore in wind manufacturing at the site. Future capital expenditure will focus on automation, advanced tooling systems, and the development of recyclable blade materials, aligning with sustainability goals.
Strengthening India’s Global Wind Position
As reported by manufacturingtodayindia.com, India currently ranks fourth globally in cumulative installed wind capacity, with approximately 55 GW deployed. In addition, the country boasts nearly 20 GW of annual wind manufacturing capacity and achieves localisation levels of 70–80 per cent across the wind value chain. Therefore, initiatives such as the 91.2-metre blade manufacturing project further reinforce India’s emergence as a global wind manufacturing hub while accelerating the clean energy transition.
