Tata Power has commissioned the second element of its Jalpura-Khurja transmission project in Uttar Pradesh, strengthening power infrastructure for the National Capital Region (NCR) with 162 CKM of lines and a 1,000 MVA substation.

The facility was executed through TP Jalpura Khurja Power Transmission Limited, a wholly owned subsidiary of Tata Power. The commissioning adds critical high-voltage connectivity between Khurja, a key power node in Western Uttar Pradesh, and Jalpura.

Key infrastructure highlights

The newly commissioned facility represents a significant addition to the NCR's power transmission network. The project combines high-capacity transmission lines with a large-scale substation to support the region's growing electricity demand.

The following table summarises the key parameters of the newly launched infrastructure:

Significance for NCR power network

The 400KV Jalpura-Khurja transmission line adds substantial capacity to the NCR's power grid. With 162 CKM of lines and a 1,000 MVA substation, the infrastructure is designed to enhance transmission reliability and meet the electricity requirements of the region.

The 162 CKM transmission corridor comprises two circuits of approximately 81 km each. It establishes a critical high-voltage link between Khurja and Jalpura, enabling efficient transmission of power towards NCR and Noida.

The newly commissioned 400/220 kV GIS substation at Jalpura serves as a major power gateway. It enables the transfer of power from the 400 kV high-voltage grid to the 220 kV network, supporting the region's increasing power requirements while enhancing reliability, resilience, and efficiency.

Broader portfolio impact

With this commissioning, Tata Power further strengthens the infrastructure required to support growth in NCR and Western Uttar Pradesh. The company's total transmission portfolio now stands at 7,900 circuit kilometres of lines operational and under execution across India.

Tata Power Renewable Energy Limited (TPREL) has commissioned a 100 MW group captive solar project in Tamil Nadu, expanding its total utility portfolio to 12.3 GW. The facility, located in Kayathar, marks the company’s surpassing of the 7 GW operational capacity milestone.

The project, designated TNGC-2, is situated in Vellalankottai and Nalandhula villages. It represents a significant step in the Tata Group’s decarbonisation strategy, supplying clean power directly to three key subsidiaries. This expansion reinforces TPREL’s position as a major player in India’s clean energy transition.

Project Specifications and Technology

The Kayathar project is engineered with India’s first deployment of Flexible Terrain Compatible (FTC) Single Axis Tracker technology for a Tata project. This innovation aims to maximise energy generation across varying terrain conditions while improving operational efficiency.

Key technical specifications include:

• Modules: 261,660 Mono PERC bifacial solar modules
• Technology: FTC Single Axis Tracker
• Grid Connection: Transmission via Kayathar 400 kV Grid Substation (GSS)
• Annual Generation: 240.63 million units (MUs)
• Carbon Offset: Approximately 1.5 lakh tonnes of CO2 emissions per annum

Energy Distribution Among Beneficiaries

The power generated will be allocated among three Tata Group entities, supporting their specific operational needs. The distribution reflects the varying energy demands of manufacturing, electronics, and real estate sectors within the group.

Portfolio Growth and Pipeline

With this commissioning, TPREL’s operational capacity now exceeds 7 GW. The existing portfolio comprises more than 5.7 GW of solar assets and 1.3 GW of wind energy assets. This mix highlights the company’s diversified approach to renewable generation.

What the Numbers Show

The composition of the operational portfolio reveals a heavy reliance on solar energy, which accounts for approximately 81% of the 7 GW operational capacity (5.7 GW solar vs 1.3 GW wind). While wind provides diversification, the current operational base is predominantly solar-driven. This concentration aligns with the broader pipeline strategy, where solar also constitutes a larger share (2.2 GW) compared to wind (3.1 GW) in the upcoming additions, though the gap narrows significantly in the development stage.

Future Expansion Plans

TPREL has an additional 5.3 GW under various stages of development. This pipeline includes:

• 2.2 GW of solar projects
• 3.1 GW of wind projects

These assets are slated for phased commissioning over the next 6 to 24 months. The addition of significant wind capacity in the pipeline suggests a strategic move to balance the currently solar-heavy operational portfolio in the medium term.

This expansion supports India’s target of achieving 500 GW of non-fossil fuel capacity by 2030. Tata Power continues to leverage its expertise in large-scale renewable assets, including utility-scale solar, floating solar, and Battery Energy Storage System (BESS) projects.
