Wind turbine manufacturer Vayona Energy has signed an agreement with independent power producer Oyster Renewable Energy to supply 64.8 MW of its 18 SG 3.6-145 wind turbines for a project in Kadapa, Andhra Pradesh.

Vayona will also provide long-term operations and maintenance (O&M) services for the turbines.

The wind turbines have a capacity of 3.6 MW each.

Vayona was formed in late 2025 as an independent wind energy platform by global alternative asset management firm TPG and a MAVCO-led consortium, following the acquisition of Siemens Gamesa’s onshore wind business in India and Sri Lanka.

The company stated that it has a customer order book and an O&M portfolio of approximately 7 GW.

Vayona’s SG 3.6-145 and other similar-capacity wind turbines have secured an order intake exceeding 3.6 GW since their launch in India. The order intake surpassed 2 GW in December 2025.

Critical components of these wind turbines will be manufactured at Vayona’s facilities in Mamandur, Tamil Nadu. The turbine supply is scheduled to commence from the first quarter of 2026. 

The company has a wind portfolio of approximately 12 GW in operational and development assets.

India added 6.3 GW of wind power capacity in 2025, an 85.2% year-over-year (YoY) increase from 3.4 GW in 2024, according to Mercom India Research. The additions marked the highest annual wind installations recorded in the country. Andhra Pradesh installed 4.3 GW of wind energy during the year.

India installed 1.38 GW of wind energy capacity in the fourth quarter of 2025, a 73% YoY growth from 800 MW in Q4 2024. Capacity additions were down 4% in a quarter-over-quarter comparison.

Last year, the Ministry of New and Renewable Energy amended the standard operating procedure (SOP) for prototype testing under the Approved List of Models and Manufacturers (ALMM) for wind and wind turbine components, while the SOPs were issued in October. For a wind turbine model to qualify under ALMM (Wind), it must possess a valid type certificate issued by an accredited certification body.
