Tata Power gets ₹521.07cr Ryapte LOI in Karnataka 2026

Stock trades flat as filing highlights new transmission win

Shares of Tata Power Company Ltd were trading on a flat note on the day the company disclosed a fresh transmission project development. The Tata Group firm said it has received a Letter of Intent (LOI) from REC Power Development and Consultancy Ltd (RECPDCL) for the acquisition of Ryapte Power Transmission Ltd. RECPDCL is a wholly-owned subsidiary of REC Ltd.

The LOI relates to a project special purpose vehicle (SPV) created for a transmission infrastructure project in Karnataka. Tata Power disclosed that the project carries annual transmission charges of ₹521.07 crore, indicating the contracted fee payable for the asset once it becomes operational under the agreed structure.

Who issued the LOI and what Tata Power plans to acquire

According to the company’s disclosure, the LOI has been issued by RECPDCL, which typically anchors tariff-based competitive bidding (TBCB) processes for power transmission projects. Tata Power’s LOI is for the acquisition of Ryapte Power Transmission Ltd, the SPV associated with the project.

The company clarified two key aspects around the transaction classification. It said the contract has been awarded by a domestic entity. It also clarified that the transaction does not fall under the category of related-party dealings.

BOOT model and concession period: 35 years of transmission services

Tata Power said the project will be executed under the build-own-operate-transfer (BOOT) model. Under this structure, the selected developer builds and operates the transmission asset for the contracted period and later transfers it as per the terms of the agreement.

The company stated that the project will provide transmission services for 35 years from the Scheduled Commercial Operation Date (SCOD). This long concession period is typical for regulated transmission assets where revenues are linked to contracted transmission charges.

Timeline: SCOD targeted 30 months after SPV transfer

On execution timelines, the company said SCOD is expected to be achieved 30 months after the transfer of the SPV. This effectively sets the project’s development and commissioning schedule once the SPV acquisition is completed.

The timeline is important for investors tracking when annual transmission charges could begin, because transmission service revenues are tied to operational milestones. The disclosure does not specify interim milestones beyond the SCOD expectation.

Project scope: about 250 km network across Karnataka

Tata Power said the project entails development of an around 250-km transmission network across Karnataka. The scope includes 400 kV double-circuit transmission lines, 220 kV double-circuit lines, and 220 kV underground cable systems.

The filing points to a mix of overhead lines and underground cable links, which can be relevant from a right-of-way and urban connectivity standpoint. The company has not disclosed the project cost in the provided information.

Substations planned: AIS at Ryapte and GIS at Doddathaggalli

As part of the project, Tata Power will establish a 5x500 MVA, 400/220 kV air-insulated substation (AIS) at Ryapte in Tumkur district. It will also establish a 3x500 MVA, 400/220 kV gas-insulated substation (GIS) at Doddathaggalli near Hosakote.

The scope also includes installation of associated bus reactors. Together, these assets are intended to support reliable power evacuation and transmission through the corridor described in the project.

Connectivity plan: linking multiple substations in the corridor

Tata Power said the transmission corridor will interconnect substations at Ryapte, Doddathaggalli, Kolar, Ekarajapura, Hosakote and Sarjapura. The interconnection will be achieved through a combination of overhead transmission lines and underground cable links.

By explicitly listing the nodes, the disclosure outlines the geographic spread and the network nature of the project. The company’s note does not provide further technical parameters beyond voltage levels, circuit configuration, and substation capacity.

Key facts at a glance

Market impact: what the disclosure signals, and what it does not

The immediate market reaction, as described in the update, was muted, with Tata Power shares trading flat even after the LOI disclosure. While the filing sets out annual transmission charges of ₹521.07 crore, it does not provide capital expenditure details, financing structure, or expected returns.

What the disclosure does establish is revenue visibility in the form of annual transmission charges once the project achieves SCOD, and a defined operating period of 35 years from that date. It also signals continued participation in regulated transmission tenders under frameworks such as tariff-based competitive bidding, which the filing references.

Why this matters for Tata Power’s transmission strategy

Transmission assets under BOOT frameworks can provide long-dated contracted cash flows, subject to commissioning and performance obligations. The project’s 30-month SCOD expectation highlights execution discipline as a key variable, because revenue commencement depends on the asset becoming operational.

The project also expands Tata Power’s transmission footprint in Karnataka through a specified corridor and two greenfield substations, combining AIS and GIS technologies. The company’s clarification that the award is domestic and not related-party addresses governance disclosures that investors typically watch in large infrastructure transactions.

Conclusion

Tata Power’s LOI from RECPDCL to acquire the Ryapte Power Transmission SPV adds a new Karnataka transmission project with annual transmission charges of ₹521.07 crore and a 35-year BOOT service period. The next operational marker disclosed by the company is SCOD, which it expects to reach 30 months after the SPV transfer, alongside the build-out of an around 250-km network and two substations in the state.
