India TBCB transmission projects

Interstate (ISTS) and intrastate schemes awarded through tariff-based competitive bidding since January 2022, plus schemes now under bid or approved for bidding. Capex here is the winning developer's project investment, recovered through the transmission tariff; EPC contracts the developers award are a separate market and are listed apart, never added in. POWERGRID holds — of the — awarded schemes; the two HVDC corridors it won (Khavda–Nagpur, Barmer–South Kalamb) and Adani's two (Bhadla–Fatehpur, KPS3–South Olpad) carry the largest capex.

How this was compiled, and how far to trust each figure

Projects come from the CEA report on under-construction TBCB projects (May 2026), CTUIL regional status sheets, bid-coordinator notices from PFC Consulting and REC Power Development & Consultancy, NCT approvals, stock-exchange disclosures by the winners, and trade coverage (T&D India, Power Line, Mercom). Each scheme links to the source used for it.

  • TBCB investment vs EPC. Capex is the project cost the winning transmission developer invests and recovers through the 35-year tariff. Where the developer has awarded EPC or equipment packages (for example HVDC converter contracts), the contractor is named in its own field and its contract value is not added to any total.
  • Capex basis. "NCT / BPC estimate" is the cost the National Committee on Transmission or the bid coordinator published. "Developer stated" is the figure the winner announced. "Estimated from quoted tariff" scales the winning annual transmission charge by roughly 8.5 to 9 times, which matches schemes where both are public. "Indicative estimate from scope" is a rough figure from line length and transformer count, typically good to about ±30 to 40 percent.
  • Routes. Lines join approximate substation locations and do not follow the surveyed alignment. HVDC corridors are drawn through intermediate points only to keep them readable.
  • Older awards. Schemes marked "Status not re-verified" were awarded in 2022–23 and are likely complete or close to it, but no current status report was found for them.
  • Dates. "Awarded" is the LoI or SPV transfer month. Scheduled COD is the contractual date; expected COD is the CEA or CTUIL anticipated date where reported, otherwise the contractual period from transfer.
  • Left out. RTM schemes (for example Ladakh HVDC and Satara Part B), schemes awarded before January 2022, a few small 2022–23 schemes whose scope could not be located (WRES-XXVII, WRES-XXVIII/XXIX, ER–NER strengthening), and SPV acquisitions of existing assets. Intrastate TBCB schemes are covered where a bid coordinator notice or trade report could be found (Maharashtra, Karnataka, UP, MP, Rajasthan, Bihar, J&K, Haryana); smaller state tenders and pre-2024 state awards may be missing. Annulled bids (Ambernath, Joda–Barbil) are left out.
  • Pipeline cross-check (Nov 2026). Bid dates and stages were re-checked in November 2026 against bid-coordinator notices and trade reports. A few pre-RFP schemes (Siot, ERES-56, NERGS-V, Dhule PS Phase-II, Nabinagar-II/Barun) have no public notice yet; they are shown as low-confidence with indicative locations.
  • Schemes under bid. Bids are split into three stages: RFP open (bids not yet due), bids under evaluation (e-reverse auction pending or held, no result), and L1 declared (winner named, LoI awaited). They are drawn as dotted lines with hollow nodes in shades of one colour, darker as the bid gets closer to award. Their capex is the bid coordinator's or NCT's estimate, or an internal estimate from scope, and bid dates move often. Bikaner-V Parts C and D are assumed to be out to bid alongside Parts A and B, and some substation locations for new schemes are approximate.
