The under-construction power transmission portfolio of Tata Power surpassed 2,000 ckm, as of June 30, 2026.
The milestone was crossed with the Ryapte intrastate-TBCB scheme in Karnataka for which Tata Power received the letter of intent in the first quarter (Q1: April to June) of FY27. With an envisaged investment of over Rs.4,000 crore, the Ryapte project envisages 491 ckm of transmission lines within the southern state.
Tata Power’s under-construction power transmission portfolio has now touched 2,332 ckm that will be commissioned in phases between the remaining part of current fiscal year FY27 and FY29. (See Table 2)
In a media interaction discussing the company’s performance in Q1FY27, Dr Praveer Sinha, CEO & MD, Tata Power, said that the company was very excited about emerging opportunities in the intrastate transmission system (InSTS) space under the tariff-based competitive bidding (TBCB) mechanism.
Tata Power now has three InSTS-TBCB scheme – one each in Uttar Pradesh, Maharashtra and Karnataka. Regarding the Maharashtra (Jejuri-Hinjewadi) and Karnataka (Ryapte) schemes, Dr Sinha said that the process of acquiring the project SPVs would be completed soon.
Meanwhile, Tata Power is expected to fully commission two TBCB schemes – one interstate and one intrastate – during the current fiscal year, the Tata Power top official said. The interstate scheme, housed under “TP Bikaner III Neemrana II Transmission Ltd,” involves the construction of 692 ckm of lines. The project is almost complete, Dr Sinha observed, and was awaiting completion of a related line being developed by another transmission service provider.
Tata Power has envisaged capital expenditure of around Rs.40,000 crore in its power transmission business, to be deployed between now and FY30. A large part of this – around Rs.25,000 crore – will be for TBCB projects (both intrastate and interstate) while the remaining would be directed towards the Mumbai power transmission business. Incidentally, Tata Power is aiming to significantly upgrade its power T&D network in Mumbai by 2031, a plan that includes creation of a robust 400kV ring network to serve data centres and metro rail lines.
The overall power transmission portfolio of Tata Power, including both commissioned and under-construction projects, is now close to 8,000 ckm, touching 7,894 ckm as of June 30, 2026. By current thinking, this entire portfolio should turn operational by March 2029.
Completions in FY27
By March 31, 2027, Tata Power is likely to commission two greenfield power transmission projects, thereby adding 854 ckm of lines to its operational portfolio. This quantum will come from an intrastate-TBCB project in Uttar Pradesh, housed under TP Jalpura Khurja Power Transmission Ltd and an interstate-TBCB project in Rajasthan, incorporated under TP Bikaner III Neemrana II Transmission Ltd.
In the current fiscal year, Tata Power is also likely to make progress on two interstate-TBCB schemes in Odisha – TP Paradeep and TP Gopalpur. These are likely to commission during FY28. Dr Praveer Sinha noted that even as TP Gopalpur was awaiting final transmission licence from Central Electricity Regulatory Commission (CERC), project work was underway. The Gopalpur scheme is envisaged to supply RE power to upcoming green hydrogen units in the Gopalpur area of Odisha.
Resurgent Power
Though Tata Power today has a portfolio of six TBCB projects that it has won directly through international competitive bidding, the Tata Group entity entered the TBCB-related power transmission space through the acquisition of one ISTS and one InSTS scheme by Resurgent Power Ventures, in which Tata Power has 26 per cent equity holding. Both the projects were stressed assets, acquired whilst under construction. The two projects have since been commissioned and have together contributed 1,823 ckm to Tata Power’s transmission portfolio. (See Table 1)
