Suzlon Targets India’s 30 GW Wind Repowering Opportunity
Suzlon Energy makes and develops wind power projects in India.
Its vice chairman says many old wind turbines could be replaced with newer, more efficient ones.
He estimates this opportunity could involve about 30 GW of capacity in India.
Suzlon may reuse some existing foundations and towers to make upgrades cheaper and faster.
India installed 6 GW of wind capacity last year and is expected to install 8 GW this year.
The country still needs to build about 10 GW each year to reach its 100-GW goal by financial year 2030.
Suzlon also wants to build more complete projects instead of only selling turbines.
It is entering battery storage because demand is growing.
The company says offshore wind is currently too expensive and difficult for India, so near-term growth will mainly happen on land.
Suzlon Vice Chairman Girish Tanti estimates India’s wind repowering opportunity at about 30 GW.
Repowering involves replacing aging turbines, while potentially reusing existing foundations and towers to reduce costs and time.
India added 6 GW of wind capacity last year, with 8 GW expected this year.
Tanti expects India to add about 30 GW by financial year 2030, below the 10-GW annual pace needed for the 100-GW goal.
Suzlon is expanding into project development and battery storage while expecting future margins of 17% to 18%.
- Who
- Suzlon Energy Vice Chairman Girish Tanti and Suzlon Energy are central to the announcement.
- What
- Suzlon is targeting India’s wind-turbine repowering market, estimated by Tanti at about 30 GW, while expanding into project development and battery storage.
- When
- The comments were made at WindEnergy Hamburg; India’s capacity targets refer to last year, this year, and financial year 2030.
- Where
- India, with comparisons to Europe and China’s wind markets.
- Why
- Aging turbines can be replaced with more efficient models, while India’s wind installations and demand for integrated renewable-energy projects are increasing.
Growth Opportunity
Industry Constraints
Wind repowering
Growth Opportunity
Suzlon sees roughly 30 GW of potential in India and has won a small repowering order, with more opportunities possible.
Industry Constraints
Repowering requires renegotiating land agreements, power contracts, and grid permissions, making it more complex than simply replacing turbines.
India’s wind expansion
Growth Opportunity
India added 6 GW last year, is expected to add 8 GW this year, and is beginning to gain momentum in wind development.
Industry Constraints
Installations remain below the roughly 10 GW per year needed to reach the 100-GW FY30 goal, while grid availability and permitting continue to delay projects.
Offshore wind
Growth Opportunity
Tanti expects India’s near-term wind growth to continue on land, where projects are more viable.
Industry Constraints
India is not yet ready to follow Europe into offshore wind because coastal wind conditions are less favorable and offshore projects cost two to three times more than onshore projects.
- India repowering opportunity
- About 30 GW, according to Girish Tanti.
- European repowering opportunity
- About 50 GW, according to Tanti.
- India wind additions last year
- 6 GW.
- Expected additions this year
- 8 GW.
- India’s FY30 target
- 100 GW of wind capacity, requiring roughly 10 GW of annual additions.
- Suzlon future margin outlook
- 17% to 18% for the full year, despite quarter-to-quarter fluctuations.
- Suzlon share price
- ₹40.61 at Thursday’s close, down 4.2% that day and 23% year to date.
