Wind energy extends beyond electricity generation. It sits at the intersection of manufacturing, industrial competitiveness, corporate sustainability and digital transformation. “As India accelerates its energy transition, the wind sector is gaining a role capable of driving economic growth, strengthening supply chains and supporting the country’s ambitions in advanced manufacturing,” says Jayasurya Francis, Director -India, Global Wind Energy Council (GWEC).
India has quietly built one of the world’s most comprehensive wind manufacturing ecosystems. According to a Niti Aayog report, it has an annual manufacturing capacity of approximately 17.25 GW. The ecosystem extends well beyond turbine assembly. Domestic annual manufacturing capacity includes about 5200 MW of towers, 8000 MW of gearboxes, 11,590 MW of castings, 10,000 MW of yaw drives and 5000 MW of pitch drives.
LOCALISATION WILL OPEN OPPORTUNITIES
The importance of this manufacturing ecosystem goes far beyond meeting India’s own wind energy needs. “As companies look to diversify their supply chains and reduce dependence on a few manufacturing hubs, India has a real opportunity to emerge as a major global supplier of wind turbines and their components,” points out Jayasurya. The economics are compelling. Wind turbine towers make up about 26 per cent of total turbine costs, blades account for 22 per cent and gearboxes contribute another 12 per cent. Together, these components represent nearly 60 per cent of a turbine’s value. As more of the supply chain is localised, India stands to gain not just through jobs and exports, but also the growth of advanced manufacturing capabilities that can support long-term competitiveness.
ESG is driving demand
Corporate renewable energy procurement has emerged as one of the fastest-growing drivers of clean energy investment globally. The rise of artificial intelligence and cloud computing have accelerated this trend, with technology giants such as Google, Microsoft, Amazon and Meta committing billions of dollars. India too is witnessing a similar shift. It is increasingly becoming a business necessity rather than a compliance requirement. “Thirty years ago, wind power was adopted to reduce electricity costs. Today, large technology companies, cloud-service providers and data-centre operators are among the fastest-growing consumers of renewable energy,” says Jayasurya.
Data-centre operators are increasingly signing long-term renewable-energy agreements, with companies such as Sify committing 231 MW of wind and solar capacity for hyperscale facilities, while newer AI-ready campuses are securing dedicated renewable energy supplies to meet both sustainability targets and rising electricity demand. Many of these facilities require reliable, round-the-clock clean energy. Wind combined with solar and battery storage can help create a more stable solution. As more corporations adopt net-zero commitments, demand for clean power is expected to remain structurally strong.
Rise of digital wind farm
Perhaps the most transformative shift in the sector is occurring not in manufacturing facilities or project sites, but in data centres and control rooms. The future of wind energy will increasingly be shaped by digital technologies. Modern wind farms are evolving from mechanical infrastructure into intelligent energy systems. Advanced sensors, predictive maintenance systems and real-time data analytics allow operators to anticipate faults, optimise turbine performance and reduce downtime. This allows wind farms to be managed with unprecedented efficiency.
This increased connectivity also creates new vulnerabilities. The Niti Aayog report notes concerns regarding remote turbine management, overseas data servers and dependence on imported power plant controllers and supervisory control systems. Industry guidelines now emphasise vulnerability assessments, penetration testing, firmware updates, communication protocol compliance and regular cybersecurity audits for critical infrastructure. Utilities are required to implement information security management systems and conduct periodic audits of both IT and operational technology systems to strengthen resilience against cyber threats. The future competitiveness of the sector will therefore depend not only on manufacturing turbines but also on securing the digital infrastructure that powers them.
India’s wind sector is entering a new phase of development. The first chapter was about harnessing wind resources. The second focused on scaling deployment and reducing costs. The third chapter, now unfolding will be defined by manufacturing competitiveness, ESG-driven demand, offshore opportunities and digital intelligence.
TN: The manufacturing powerhouse
Tamil Nadu remains India’s undisputed wind component manufacturing powerhouse, leveraging an advanced heavy-engineering supply chain and strategic maritime infrastructure.
While Gujarat leads in total installed grid capacity, Tamil Nadu ranks first in manufacturing maturity, housing major global OEMs like Envision Energy, Senvion India, Siemens Gamesa, Vayona Energy , Vestas, across its primary industrial hubs in Trichy, Coimbatore and Chennai.
The state is also emerging as a global engineering and innovation hub for the wind sector. Global OEMs have established major engineering and Global Capability Centre(GCC)operations in chennai supporting global design, digitalisation,analytics and product devlopment. Vestas’ largest global office in Chennai alone houses over 2500 professionals supporting worldwide R&D, engineering and digital functions, while companies such as Nordex, Rambool and COWI have established major engineering centres in the state. These centres are creating high-value jobs positioning Tamil Nadu not only as a manufacturing base but also as a global hub for wind-energy design,innovation and project execution.
Tamil Nadu’s advantage is further strengthened by favourable industrial policies, repowering opportunities and the centre’s Rs 6853 crore offshore wind Viability Gap Funding (VGF) programme.
For export logistics, Tamil Nadu vastly outperforms competing western Indian states when handling over-dimensional cargo. V O Chidambaranar Port in Thoothukudi serves as India’s leading gateway for wind energy exports, featuring dedicated 100,000 sq. m. staging yards built specifically for handling and shipping blades up to 90 meters long. Kamarajar Port in Ennore too offers a highly skilled workforce trained for composite moulding.
Reflecting this strength, Nordex India has invested Rs 1000 crore for wind turbine component expansion project in Vengal near Chennai to manufacture advanced 4 MW to 7 MW+ nacelles and rotor blades. This solidifies the state’s role alongside global electronics players like Ingeteam that assemble specialised turbine electronics.
