India’s Tata Power(TTPW.NS)announced plans on Tuesday to establish the country’s largest solar wafers and ingots manufacturing facility,with a total capacity of 10 gigawatts.Chief Executive Praveer Sinha said the plant will complete Tata Power’s integrated solar manufacturing chain,as the company already operates 4.9 GW of combined solar cell and module production capacity.
The new facility will focus on producing ingots and wafers,which serve as the base materials for solar cells.Sinha explained during a post-earnings call that the company aims to strengthen its upstream production,noting:“We find that there’s already adequate capacity of modules and many cell plants are under construction in India.”He added that developing domestic capacity for ingots and wafers has become strategically important,especially as higher U.S.tariffs on Indian solar products have made module exports less competitive.
Currently,the Adani Group operates a 2 GW annual ingot and wafer manufacturing plant,making Tata Power’s planned project the largest of its kind in India once completed.The initiative aligns with the Indian government’s long-term strategy to boost local production of key solar components and reduce dependence on imported materials,particularly toward the end of the decade.
The federal government has also announced plans to extend output-linked financial incentives to manufacturers of ingots and wafers to promote local value addition in the solar industry.Sinha said Tata Power is assessing available federal and state-level financial support options for the project.“A final call on the total investment will be made in the next two months,”he said,indicating that feasibility studies and site evaluations are already underway.
The planned 10 GW plant will strengthen Tata Power’s position in the domestic renewable energy manufacturing ecosystem,allowing the company to supply a full range of solar components—from raw materials to finished modules.This vertical integration is expected to improve cost efficiency and enhance supply chain resilience in India’s solar sector.
In addition to expanding its solar manufacturing portfolio,Tata Power is exploring opportunities in nuclear power generation.India currently has just over 8 GW of nuclear capacity but aims to raise this figure to at least 100 GW by 2047 as part of its long-term energy diversification strategy.The company’s potential entry into nuclear energy underscores its broader focus on clean,stable,and scalable power sources.
Tata Power’s latest investment plan reflects both growing domestic demand for renewable energy solutions and India’s policy emphasis on energy self-reliance.By advancing local manufacturing of solar ingots and wafers,the company aims to play a central role in supporting national goals for sustainable energy expansion and reduced import dependence.
