India’s wind manufacturing sector is entering a new phase as Adani New Industries Ltd (ANIL) begins producing the country’s longest onshore wind turbine blades, measuring 91.2 metres, at its Mundra facility in Gujarat. The development reflects growing domestic capability supported by policy measures and a strong push toward clean energy self-reliance.
The new blades will power next-generation turbines designed to improve energy generation, especially in low- and medium-wind locations. The Mundra plant currently produces 78.6 metre and 80.5 metre blades.
The 91.2 metre blade marks a major advancement in design, materials engineering and manufacturing scale. Industry sources indicate that initial sets have already been installed on a new turbine model, with serial production expected within the current calendar year.
Why blade size matters
Longer blades combined with higher rated capacity significantly improve wind energy output. A 91.2 metre blade enables a rotor diameter of about 185 metres, sweeping nearly 26,600 square metres. A larger swept area allows turbines to capture more wind energy, increasing capacity utilisation and power output.
This is particularly important for India, where many potential wind sites fall in low- to medium-wind zones. Larger rotors and higher hub heights make these sites commercially viable, expanding deployment beyond traditional high-wind corridors. The shift toward turbines rated above 5 MW reflects both geographic and technological progress.
A blade of this size is comparable to a football field and taller than a 30-storey building. Each rotation sweeps an area larger than 3 football fields combined.
Manufacturing scale and investment
ANIL’s Mundra facility currently has an annual blade manufacturing capacity of 2.25 GW, equivalent to around 450 blade sets per year. The company plans to scale this to 5 GW in phases, with a long-term target of 10 GW.
Mundra is being developed as an integrated renewable manufacturing hub, producing wind turbines, solar modules and supporting components. Investments in wind manufacturing have reached up to Rs 3,000 crore. Future spending will focus on automation, advanced tooling and research into recyclable blade materials and larger rotor designs.
India’s wind manufacturing momentum
India ranks 4th globally in cumulative installed wind capacity, with around 55 GW operational. The country is also the world’s 3rd-largest wind manufacturing base, with about 20 GW of domestic capacity, meeting nearly 10 per cent of global demand.
Localisation across the wind value chain stands at 70 to 80 per cent. Blade manufacturing alone accounts for nearly 16 GW, giving India close to 10 per cent of global blade capacity.
In 2025, India added 6.3 GW of wind capacity, the highest annual addition so far, marking an 85.2 per cent year-on-year increase, according to Mercom Capital Group.
Policy support and supply chains
Government support has strengthened domestic manufacturing. Earlier this year, authorities approved a Rs 7,280 crore programme to build an integrated ecosystem for rare earth permanent magnets, a key input for wind turbines and electric vehicles. The initiative targets 6,000 tonnes per annum of capacity to reduce import dependence.
The road ahead
In the current financial year, ANIL expects to deliver up to 1.25 GW of turbines to external customers and a similar volume for projects of Adani Green Energy Limited, fully utilising existing capacity.
As India accelerates its renewable transition and strengthens its position as a clean energy manufacturing hub, domestically produced ultra-long blades and higher rated turbines signal a major shift in scale, integration and technological capability.
