Tata Power's subsidiary, TP Solar, hit a production milestone at its Tirunelveli facility, outputting 1 GW of solar modules in Q2 FY27. With a total H1 output reaching 2 GW for modules and 1.8 GW for cells, the company is successfully scaling its 4.3 GW unit to meet domestic solar demand.
Tata Power Subsidiary TP Solar Reports Strong Production Growth in Q2 FY27
Module production reached 1 GW in Q2 FY27 with H1 output totaling 2 GW.
Cell production hit 0.9 GW in Q2 FY27, bringing H1 cumulative output to 1.8 GW.
Reader Takeaway: Strong operational scaling at the Tirunelveli plant enhances domestic supply chain positioning amidst rising solar energy demand.
What just happened
TP Solar, the manufacturing arm of Tata Power Renewable Energy Limited, has released its latest production figures for the second quarter and the first half of FY27. The company's massive 4.3 GW solar cell and module facility located in Tirunelveli, Tamil Nadu, is demonstrating significant operational momentum. The facility achieved a production output of 1 GW of solar modules and 0.9 GW of solar cells during the July-September 2026 quarter.
Why this matters
The facility's performance is critical to Tata Power's strategy of achieving self-sufficiency in the solar value chain. By producing 2 GW of modules in the first half of the year, the company is effectively translating its Rs 4,300 crore investment into tangible manufacturing output. The plant utilizes advanced TOPCon and Mono PERC technologies alongside AI-driven automation, ensuring high-efficiency output that aligns with the government's current energy transition goals.
What changes now
TP Solar is now well-positioned to capitalize on India's push for local manufacturing. All modules produced at this site are fully compliant with Domestic Content Requirement (DCR) norms and are listed under the Approved List of Models and Manufacturers (ALMM). This certification allows the company to participate in a broader range of government-tendered renewable energy projects, potentially securing a larger share of the domestic market.
Risks to watch
While operational ramp-up is steady, the facility faces risks associated with global supply chain dependencies for raw materials and the high intensity of competition within the domestic solar manufacturing sector. Investors should watch for further updates on capacity utilization rates as the plant moves toward its full 4.3 GW design capacity.
What to track next
Future quarterly updates regarding capacity utilization at the Tirunelveli plant and the integration of this output into Tata Power’s broader utility-scale project pipeline will be the key indicators of long-term value accretion for shareholders.
