Recently, Indian company Tata Power announced plans to build the country’s largest solar ingot and wafer manufacturing plant, with a total capacity of 10 gigawatts (GW).
During an earnings conference call, Tata Power CEO Praveer Sinha revealed that the new facility will focus on ingot and wafer production, while the company currently already possesses 4.9 GW of solar cell and module manufacturing capacity. He pointed out that with India’s existing module capacity nearing saturation and numerous cell factories under construction, developing upstream ingot and wafer capacity holds significant strategic importance. This is particularly relevant against the backdrop of the U.S. imposing high tariffs on Indian solar products, which has weakened the export competitiveness of modules.
Currently, the Adani Group operates a 2 GW ingot and wafer plant. Upon completion, Tata Power’s planned 10 GW project will become the largest of its kind domestically. This plan aligns closely with the Indian government’s strategy to reduce reliance on imports of key solar components by around 2030. The federal government has already announced a Production Linked Incentive (PLI) scheme for ingot and wafer manufacturers. Sinha stated that the company is evaluating federal and state-level financial support, and feasibility studies and site selection have commenced. A final investment decision is expected within the next two months.
Industry analysis suggests that once this plant is operational, Tata Power will possess an integrated supply chain capability—from ingots and wafers to finished modules. This vertical integration is expected to enhance cost efficiency and strengthen the resilience of the industrial supply chain.
