India is exploring ways to upgrade around 25 GW of ageing wind Farms, as the government looks to increase generation from existing installations while pursuing its 100 GW wind power target by 2030.
At the eighth edition of Windergy India 2026 in Chennai on 8 October, Union Minister for New and Renewable Energy Pralhad Joshi said the government was working on strategies to repower around 25 GW of older wind energy projects.
The proposal focuses on wind installations nearing the end of their operational lives, where ageing turbines and equipment could be replaced with modern technology. The government has not yet announced which projects will be covered or when the repowering exercise will begin.
What Does Repowering Mean for India?
Instead of developing an entirely new wind farm, repowering allows developers to replace older turbines with newer models that can generate more electricity from available wind resources. The actual gains depend on wind conditions, site characteristics, grid connectivity and the technology installed.
For India, this could offer a way to make better use of existing wind sites as the country expands its renewable energy capacity. However, the proposed 25 GW figure refers to projects being considered for repowering, not additional capacity already approved or installed.
The Road to 100 GW
India’s wind power sector added approximately 6.05 GW of capacity in FY2025–26. Around 3 GW more was installed between April and September 2026, according to reports quoting the minister. Joshi also expressed confidence that wind capacity additions in FY2026–27 would exceed the previous financial year’s level.
The country’s installed wind power capacity stood at 59.20 GW as of 30 September 2026. Reaching 100 GW by 2030 will require further capacity additions through new projects, alongside efforts to improve the performance of existing installations.
Tamil Nadu, Gujarat and Andhra Pradesh are among India’s major wind power states, although the government has not specified where the proposed repowering initiative will begin.
The next step will be to establish which ageing projects are suitable for upgrades and how the process will be implemented. Until the government releases further details, the 25 GW proposal remains an initiative under development rather than a confirmed repowering programme.
