Exel Composites, a global composites manufacturer, and Suzlon Energy have signed a new multi-year supply agreement for pultruded carbon fibre planks used in wind turbine blade spar caps
At the time of signing, the parties estimated that future deliveries under the agreement would exceed EUR 100 million through March 2029.
Under the agreement, Exel Composites’ India-based joint venture Kineco Exel Composites India (KECI) will supply an agreed share of Suzlon’s requirements for the products covered by the agreement. The final value and delivery timing may vary depending on Suzlon’s actual production requirements and resulting order volumes.
The agreement expands on a collaboration that began in 2024 and supports the ramp-up of Exel’s manufacturing operations in India. Exel and Suzlon began collaborating in 2024 under a two-year supply agreement; this led to the EUR 10 million purchase order Exel announced in February 2025, when the parties agreed not to disclose Suzlon’s name.
The new agreement extends the collaboration and covers deliveries through March 2029, providing a longer-term framework for the companies to plan sourcing and production.
Amit Agrawal, senior vice president, Global Procurement at Suzlon Energy Limited, said, “We are pleased to further strengthen our cooperation with Kineco Exel through this multi-year agreement. Reliable supply, consistent product quality and local manufacturing capability are important in supporting our wind turbine blade programs and sourcing requirements.”
Growing wind power manufacturing capability in India
Under the agreement, Kineco Exel will manufacture all supplied products at its factory in India. The factory is designed to serve the wind power industry in India and globally, and the agreement supports its continued ramp-up and utilisation.
Shekhar Sardessai, chairman of Kineco and managing director of Kineco Exel, said, “We are delighted to secure this multi-year agreement and thank Suzlon for their continued support. This is a strong endorsement of our quality, ability to deliver at scale, and the confidence our customers place in Kineco Exel. With India’s wind energy sector poised for significant growth, we are well positioned to support this opportunity through our expertise in pultrusion and advanced carbon fibre composite manufacturing.”
Paul Sohlberg, president and CEO of Exel Composites, said, “Reaching this milestone is an important step in strengthening our cooperation with Suzlon. The agreement demonstrates the value of having competitive manufacturing capacity close to one of the key markets for wind power and provides both parties with improved visibility and greater certainty regarding production capacity in India, and supports the continued ramp-up of the factory.”
Spar caps are critical structural components within wind turbine blades. Carbon fibre planks provide the strength, stiffness and load-bearing capacity required to withstand the dynamic forces encountered during operation.
As wind turbines increase in size, carbon fibre composites play an essential role in meeting the demanding mechanical requirements of modern wind turbine blades.
