Suzlon commissions India’s tallest wind turbine, the 5 MW S175 in Karnataka

Suzlon Energy Limited has commissioned its 5 MW S175 wind turbine at a project site in Vijayanagar district, Karnataka. The company said the S175 is India’s tallest wind turbine powerhouse, with a tower height of 160 metres.

According to the company, the turbine has been developed using operational insights from Suzlon’s existing 15.5 GW wind turbine fleet. The company described the S175 as India’s first turbine designed for Firm and Dispatchable Renewable Energy (FDRE) applications.

The turbine is designed for integration with solar and battery energy storage systems (BESS) to support hybrid renewable energy projects and round-the-clock (RTC) power supply models.

Turbine specifications

The S175 features a 175-metre rotor and a blade tip height of 247.5 metres. Suzlon said the turbine uses carbon-girder blade technology to improve energy capture in low and medium-wind conditions.

The company stated that the turbine is intended to expand the wind energy market beyond traditional high-wind states.

Historically, Gujarat, Rajasthan, Maharashtra, Tamil Nadu, and Karnataka have accounted for around 75% of India’s wind energy market due to favourable wind conditions. According to Suzlon, higher-capacity turbines could make additional locations commercially viable for wind power projects.

Market transition

Speaking about the launch, Suzlon Group Executive Vice Chairman Girish Tanti said the Indian market is moving from 2 MW turbines towards higher-capacity 3 MW, 4 MW, and larger machines. He said the S175 has been designed specifically for Indian wind conditions, grid requirements, and operating environments.

According to Tanti, improved turbine technology could expand India’s wind energy potential from around 350 GW to 1.1 TW by making previously unviable sites operational. Suzlon also stated that it currently has a 9 GW order book for its 3 MW turbine platform.

The company said demand is increasingly being driven by project economics, with industrial consumers and public sector undertakings preferring higher-capacity projects.

Suzlon 2.0 roadmap

Earlier this month, Suzlon announced that it is transitioning from a wind original equipment manufacturer (OEM) to an integrated renewable energy company covering wind, solar, and BESS segments. Under its “Suzlon 2.0” roadmap, the company aims to scale annual renewable energy sales to 10 GW by FY31, increase its order book to 15 GW, and expand assets under management (AUM) to 70 GW.

The company is also targeting around 40% market share in the Indian wind sector and export order intake of 3 GW by FY31.

Financial performance

Suzlon reported consolidated revenue from operations of Rs 16,679 crore for FY26, compared to Rs 10,851 crore in FY25, reflecting a year-on-year increase of 54%. Total income increased to Rs 16,842 crore from Rs 10,993 crore in the previous fiscal year. Consolidated net profit rose to Rs 3,163 crore in FY26 from Rs 2,072 crore in FY25. Profit before tax increased to Rs 2,422 crore from Rs 1,447 crore a year earlier.

The company stated that higher execution in the wind turbine generator (WTG) business and increased operational scale supported revenue and profitability growth, while higher finance costs and working capital requirements continued to impact margins and cash flows.
