Tata Power is set to expand its footprint in the solar manufacturing value chain with a proposed investment of approximately ₹6,500 crore to establish a 10 GW photovoltaic (PV) ingot and wafer manufacturing facility. The project will be executed through its subsidiary, Tata Power Renewable Energy Ltd. (TPREL), marking the company’s entry into the upstream segment of solar production.

The planned facility is expected to be developed in phases, beginning with a 5 GW capacity and scaling up to 10 GW. By moving into ingot and wafer manufacturing—critical inputs for solar cell and module production—the company aims to strengthen backward integration and enhance control over its supply chain.

This strategic move comes amid India’s increasing focus on building domestic manufacturing capabilities and reducing reliance on imports, particularly from China. With limited wafer production capacity currently available in the country, the initiative is expected to address a key gap in the solar ecosystem while supporting the government’s self-reliance agenda.

From a business perspective, the investment is likely to improve supply security and drive cost efficiencies, while enabling better margin management through vertical integration. The project is also expected to benefit from strong demand fundamentals and supportive policy frameworks for domestic solar manufacturing.

With this development, Tata Power is advancing towards becoming a fully integrated solar player, spanning the entire value chain from raw materials to modules. The initiative is poised to play a significant role in strengthening India’s solar manufacturing base and accelerating the country’s clean energy transition.
