Tata Power Renewable Energy Limited (TPREL), a subsidiary of The Tata Power Company Limited, commissioned 419 MW of utility-scale projects in Q2FY27, representing over 130% year-on-year growth compared to 182 MW in the corresponding quarter of the previous fiscal year.

The company also executed 131.2 MWhr of battery storage projects during the quarter. Of this storage capacity, 101.2 MWhr was for in-house TPREL projects, while the remaining 30 MWhr comprised third-party projects. This strong execution momentum has brought TPREL's total utility-scale operational portfolio to 7.2 GW, alongside 281.2 MWhr of battery storage capacity.

H1FY27 performance and key commissions

Building on the second-quarter performance, TPREL executed a total of 645 MW of utility-scale projects and 161.2 MWhr of storage projects in H1FY27. The storage component included 101.2 MWhr for in-house use and 60 MWhr delivered to third-party customers.

Key projects commissioned during the first half of FY27 include:

• Jewali Wind Project: 100.8 MW
• Kalasar FDRE Project: 227.5 MW solar capacity and 101.2 MWhr Battery Energy Storage System (BESS)
• Kayathar Group Captive Project: 100 MW
• Tata Steel Captive Project: 72.5 MW

The company attributes this efficiency to a resilient supply chain, experienced partners, and robust project management capabilities across diverse geographies.

Portfolio composition and future outlook

The expanded operational portfolio comprises 5.8 GW of solar, 1.3 GW of wind, and 281.2 MWhr of battery storage. This infrastructure supports India's clean energy transition and national energy security goals.

Looking ahead, TPREL expects to execute more than 2 GW of projects in H2FY27. This pipeline includes 1,075 MW of solar, 969 MW of wind, and 274 MWhr of BESS. Additionally, 300 MW of third-party projects are scheduled for execution in the second half.

By the end of the fiscal year, close to 9.3 GW of projects are expected to be executed, consisting of 6,899 MW of solar, 2,298 MW of wind, and 555.2 MWhr of battery storage. In FY28, the completion of approximately 2.6 GW of balance projects (570 MW solar, 350 MWhr battery storage, and 1,700 MW wind) is projected to take TPREL's overall operational capacity to approximately 12 GW.

What the numbers show

A comparison of quarterly execution rates reveals a significant acceleration in deployment velocity. The jump from 182 MW in Q2FY26 to 419 MW in Q2FY27 indicates that the company is not only expanding its order book but also improving its conversion rate from contract to commissioning. Furthermore, the inclusion of substantial battery storage capacity (281.2 MWhr operational) alongside intermittent renewable sources (solar and wind) suggests a strategic shift toward firming up renewable output, addressing grid stability concerns inherent in high-renewable penetration scenarios.

Tata Power Company Limited subsidiary TP Solar Limited recorded production of 1 GW of solar modules and 0.9 GW of solar cells in Q2 FY27 (July–September 2026). This output contributes to a total H1FY27 manufacturing volume of 2 GW for modules and 1.8 GW for cells.

The Tirunelveli facility operates with an installed capacity of 4.3 GW, positioning it as one of India’s largest single-location solar cell and module plants. The company invested nearly ₹4,300 crore through its renewable energy subsidiary, Tata Power Renewable Energy Limited (TPREL), to establish this infrastructure.

Production metrics and operational scale

The reported figures highlight the ramp-up phase of the manufacturing unit. The following table summarizes the production volumes disclosed for the quarter and the first half of the fiscal year.

The modules produced are compliant with Domestic Content Requirement (DCR) norms and are listed under the Government of India’s Approved List of Models and Manufacturers (ALMM). The plant utilizes advanced Tunnel Oxide Passivated Contact (TOPCon) and Monocrystalline Passivated Emitter and Rear Cell (Mono PERC) technologies.

Strategic focus on indigenization

The manufacturing hub features AI/ML-driven systems and Automated Guided Vehicles (AGVs) to enhance operational efficiency. A notable aspect of the workforce composition is that nearly 80% of employees are women, reflecting a commitment to inclusive hiring practices within the heavy manufacturing sector.

This expansion aligns with Tata Power’s broader strategy to achieve self-sufficiency in the solar value chain. The company currently holds 4.9 GW of integrated solar cell and module manufacturing capacity across its portfolio.

What the numbers show

The data reveals a consistent alignment between cell and module production rates. In Q2 FY27, the ratio of cell output (0.9 GW) to module output (1 GW) is 0.9:1. This near-parity suggests that the cell manufacturing line is operating at high utilization to feed the module assembly lines, minimizing dependency on external cell sourcing for DCR-compliant products. The H1FY27 aggregate of 2 GW modules against 1.8 GW cells indicates a slight inventory buffer or potential yield differences, but largely confirms vertical integration efficiency.
