Where it fits
Wins inter-state projects through tariff-based competitive bidding (TBCB) run by PFC and REC consulting arms, or builds them under regulated cost-plus returns (RTM). Once a line is charged it earns a fixed annual charge for 35 years from the pool of users, regardless of how much power flows. InvITs buy finished assets and pay out most of the cash.
Why it matters
These are the customers for everything else in the chain. POWERGRID had ~₹1.75L Cr of works in hand in Jun 2026 and guided ~₹37,000 Cr of FY27 capex; Adani Energy Solutions had ~₹87,000 Cr of projects under construction at Sep 2026. Their award wins are the leading indicator for tower, conductor and transformer orders.
Where the value pool sits
Low-risk annuity: regulated assets earn a 15.5% post-tax return on equity (CERC), and TBCB assets earn whatever the winning tariff allows - competition has pushed those returns lower. Long asset lives and availability-based payments make the pool bond-like.
Key drivers
~₹9.15L Cr NEP transmission plan to FY32
ISTS pipeline: ~₹4.86L Cr envisaged, of which ~₹2.22L Cr under implementation (CareEdge, Jan 2026)
Asset recycling into InvITs
Intra-state TBCB opening up in states like Maharashtra and Rajasthan
Potential bottlenecks
Equipment lead times (transformers, HVDC) delaying commissioning
Right-of-way and forest clearances
Thin TBCB bid margins as more developers compete
