Inox Wind director Devansh Jain said, "Inox is producing some of the best performing and most attractive wind turbines for the Indian market, which have been designed with consideration for Indian site conditions and low cost of operation and maintenance."
AMSC president and CEO Daniel P. McGahn said India recently introduced generation-based incentives for wind power, which incentivize project developers to select turbines that lower their levelized cost of energy and maximize their power output.
"This policy is sure to benefit a fully integrated player like Inox, who is committed to providing high-quality, competitively priced wind turbines with exceptional performance and reliability," McGahn added.
The ECS were designed and licenced by AMSC in 2009.
