Adani Arm to manufacture India’s longest 91.2-metre wind turbine blades at Mundra

NEW DELHI: Adani New Industries Limited (ANIL), which houses the Adani Group’s renewable manufacturing businesses, is preparing to manufacture 91.2-metre onshore wind turbine blades - the longest to be produced in the country - at its Mundra facility in Gujarat. The blades will be deployed on next-generation turbines designed to improve energy output, particularly at low- and medium-wind sites.

The Mundra plant currently manufactures blades measuring 78.6 metres and 80.5 metres. The new 91.2-metre blade marks a significant leap in design complexity, materials engineering and manufacturing capability. Officials said the initial set of 91.2-metre blades has already been erected on a new turbine model, with serial production expected to begin within the current calendar year.




Blade length, combined with higher rated capacity, is a critical determinant of wind energy output. A 91.2-metre blade - comparable to the length of a football field and taller than a 30-storey building - enables a rotor diameter of nearly 185 metres, sweeping an area of about 26,600 square metres. Each rotation covers an area larger than three football fields combined. A larger swept area, along with higher-rated capacity turbines, allows the turbine to capture more kinetic energy from the wind, improving capacity utilisation and increasing power output.

“This is particularly relevant for India, where a large share of potential wind sites falls in low- to medium-wind regimes. Larger rotors and higher hub heights make these locations commercially viable, expanding wind deployment beyond traditional high-wind corridors. The shift towards turbines rated above 5 megawatts (MW) is therefore as much about geography as it is about technology,” an official said.

ANIL’s blade manufacturing facility at Mundra has a current capacity of 2.25 gigawatts (GW) per annum, equivalent to about 450 blade sets annually. The company plans to scale this up to 5 GW in phases, with a longer-term ambition of reaching 10 GW.

Mundra is evolving into a multi-technology renewable manufacturing hub, housing wind turbines, solar modules and supporting component facilities within a single ecosystem. Investments in wind manufacturing so far are estimated at up to ₹3,000 crore, with future capital expenditure focused on automation, advanced tooling and materials research, including recyclable blade materials and larger rotor designs.

India ranks fourth globally in cumulative installed wind capacity, with around 55 GW operational. It is also the world’s third-largest wind manufacturing base, with a domestic manufacturing capacity of approximately 20 GW - sufficient to meet about 10% of global demand. Localisation levels across the wind value chain are estimated at 70–80%, covering towers, nacelles, blades and key components. Blade manufacturing alone accounts for nearly 16 GW of capacity, giving India close to a 10% share of global blade manufacturing.
