Tata Power has received a letter of intent (LoI) from REC Power Development and Consultancy, a wholly owned subsidiary of REC, for the acquisition of the Ryapte Power Transmission project.
The move enables Tata Power to take charge of the project special purpose vehicle (SPV) and develop power transmission infrastructure in Karnataka, India.

The Ryapte project will be implemented on a build-own-operate-transfer basis, under which Tata Power will provide transmission services for 35 years from the scheduled commercial operation date. This operation date is set for 30 months following transfer of the SPV.
The scope of the Ryapte Power Transmission project encompasses the construction and commissioning of approximately 250km of transmission network.
Planned works involve the installation of a 400kV double circuit (D/C) transmission line, a 220kV D/C transmission line and 220kV underground cables.
Specifically, the project includes a 400kV D/C connection from the Ryapte air-insulated substation to the proposed 400/220kV Doddathaggalli gas-insulated substation (GIS) substation. Another 400kV D/C line will link the existing Kolar substation to the proposed Doddathaggalli GIS substation.
In addition, a 220kV D/C line and underground cables will connect the planned Doddathaggalli substation to the substations at Ekarajapura, Hosakote and Sarjapur in Karnataka.
As part of the project, Tata Power will establish two new substations.
A 5×500 megavolt-ampere (MVA) 400/220kV substation will be set up at Ryapte in the Tumkur District, equipped with two 125MVA, 400kV bus reactors.
A 3×500MVA 400/220kV GIS will also be established at Doddathaggalli, near Hosakote, with another two 125MVA, 400kV bus reactors.
The company will be responsible for both construction and subsequent operation and maintenance over the 35-year term. The project’s annual transmission charges are set at Rs5.21bn ($55.2m).
The new infrastructure is intended to facilitate reliable evacuation of renewable power in support of Karnataka’s long-term energy plans.
According to the Resource Adequacy Assessment of Karnataka from 2024–25 to 2034–35, the state is targeting deployment of an additional 25GW of solar, 13GW of wind and 6GW of battery energy storage.
Karnataka Renewable Energy Development, appointed as the nodal agency for renewable projects, is planning a 2GW solar park at Ryapte in Pavagada Taluk, Tumakuru District. The transmission project is designed to enable efficient delivery of power generated at this location to the grid.
Tata Power, which describes itself as one of India’s largest vertically integrated power companies, recorded a profit after tax of Rs14.16bn for the fourth quarter of fiscal year 2026 (Q4 FY26) ending 31 March, an 8% year-on-year increase. The company’s revenue reached Rs159.62bn and earnings before interest, taxes, depreciation and amortisation stood at Rs42.16bn, up 10% for the period.
Its transmission network portfolio comprises 7,403 circuit kilometres (ckm), with 5,562ckm operational and 1,841ckm under construction at the time of announcing the results in May 2026. Tata Power completed two major transmission projects in Q4 FY26, adding a cumulative 1,823ckm to its network.
Earlier this year, Tata Power Renewable Energy, a subsidiary of Tata Power, announced plans to establish a new 10GW greenfield manufacturing facility for ingots and wafers in Andhra Pradesh, India.
