Tata Power Company Limited has secured a major power transmission project in India. The company announced on June 19, 2026, that it has received a Letter of Intent (LOI) from REC Power Development and Consultancy Limited (RECPDCL), a wholly owned subsidiary of REC Limited. The LOI is for the acquisition of Ryapte Power Transmission Limited, a special purpose vehicle (SPV) created to develop a key transmission network project in Karnataka.
The project will be developed under the Build-Own-Operate-Transfer (BOOT) model. It is designed to strengthen the power evacuation infrastructure in the state and support the growing electricity demand. According to the company, the project has an annual transmission charge of ₹521.07 crore, making it one of the significant additions to Tata Power’s transmission portfolio.
As part of the project, Tata Power will build and commission around 250 kilometers of transmission infrastructure. The scope includes the construction of a 400 kV double-circuit transmission line, a 220 kV double-circuit transmission line, and a 220 kV underground cable system. These facilities will help improve power transfer capacity and grid reliability across the region.
The project also includes the development of two new substations in Karnataka. One of them will be a 400/220 kV Air Insulated Substation (AIS) at Ryapte in Tumkur district. The substation will have a capacity of 5×500 MVA and will be equipped with two 125 MVAr, 400 kV bus reactors. The second facility will be a 400/220 kV Gas Insulated Substation (GIS) at Doddathaggalli near Hosakote. This substation will have a capacity of 3×500 MVA and will also include two 125 MVA, 400 kV bus reactors.
The transmission lines will connect several important substations in Karnataka. The network will link the Ryapte substation with the proposed Doddathaggalli GIS substation and also connect the existing Kolar substation to Doddathaggalli. In addition, the 220 kV lines and underground cable system will connect Doddathaggalli with existing substations at Ekarajapura, Hosakote, and Sarjapura.
Tata Power stated that the Scheduled Commercial Operation Date (SCOD) for the project is 30 months from the effective date of the SPV transfer. Once the project becomes operational, the company will provide transmission services for a period of 35 years.
The company also clarified that the contract has been awarded by a domestic entity and does not involve any promoter, promoter group, or related-party interests. The disclosure was submitted to the stock exchanges by Company Secretary Vispi S. Patel. The project marks another important step in Tata Power’s efforts to expand its transmission infrastructure business and contribute to strengthening India’s power network.
