India's wind energy got a new gust of energy as Suzlon Group formally launched the S175, a 5MW wind turbine that stands as the tallest and most powerful wind turbine ever built in India, at an official event presided over by the Union Cabinet Minister for New and Renewable Energy, Pralhad Joshi. The turbine had already been successfully commissioned at Vijayanagar in Karnataka ahead of the formal unveiling.
With a 175-metre rotor diameter, a 160-metre hybrid lattice tower, and a blade tip height of 247.5 metres (a little over an 80-floor high-rise), the turbine reaches wind layers that are stronger and more consistent than those accessible to shorter machines.
Suzlon says that the S175 is built specifically for India's low-to-medium wind regimes, where previous turbine designs struggled to generate viable returns. "The S175 embodies this philosophy and is engineered by our R&D teams specifically for Indian wind conditions, grid realities and operating environments," said Suzlon Group Executive Vice Chairman Girish Tanti.
The turbine is also India's first FDRE-ready (Firm and Dispatchable Renewable Energy) wind turbine, meaning it is engineered to integrate seamlessly into hybrid power configurations combining wind, solar, and battery storage to deliver round-the-clock (RTC) or firm power.
This is increasingly significant as India's grid operators demand reliable, schedulable renewable power rather than intermittent generation.
The S175 draws on insights from Suzlon's operational experience running 15.5 GW of turbines across India, the country's largest installed wind fleet. The company, which reported revenues of over $1.75 billion in FY26 and carries a market capitalisation of over $7.5 billion as of June 2026, has been manufacturing wind turbines in India for over three decades.
Union Minister Joshi said at the launch that the S175 "will go a long way in ensuring that we meet our wind energy ambitions — both domestically and globally," adding that the turbine "reflects India's growing strength in advanced clean energy innovation."
