Tata Power plans to set up a 10 GW solar ingot and wafer manufacturing facility with an capital investment of around INR 6,500 crore, marking a significant step in its backward integration strategy.
The proposed facility will focus exclusively on ingots and wafers and will complement Tata Power’s existing 4.8 GW of integrated solar cell and module manufacturing capacity, comprising 4.3 GW in Tirunelveli, Tamil Nadu, and 0.5 GW in Bengaluru.
The company is in discussions with several state governments regarding potential state-level incentives, and expects support under the Government of India’s Production Linked Incentive (PLI) scheme. Tata Power said the Centre is keen to rapidly scale domestic ingot and wafer capacity, given the limited existing capacity.
“Ingot/wafer manufacturing requires sophisticated technology, large capital investment, and complex execution capabilities, making it a high-barrier segment with limited competition,” the company said.
As of June 2025, India had only 5.3 GW of wafer manufacturing capacity, compared to 29 GW cell and 120 GW module capacity—according to JMK Research.
Tata Power estimates domestic ingot/wafer demand to exceed 50 GW by 2030, driven by the rapid expansion of solar cell and module manufacturing.
The company said that its planned 10 GW facility will secure raw material supply for its own manufacturing operations, while also supplying wafers to other cell and module manufacturers.
