Power Sector — Transmission (India)

Small summary: India’s power transmission sector is in the middle of a multi-year buildout driven by renewable energy (RE) integration, new load centers (data centers, green hydrogen), and grid stability needs (HVDC corridors, synchronous condensers, storage-as-transmission). The near-to-medium-term opportunity is anchored by the National Electricity Plan’s transmission investment estimate of ~₹7.9 lakh crore through FY36, with bid-outs expected to concentrate over the next ~3–4 years. The sector’s economics remain predominantly regulated/contracted (availability-based tariffs, long-duration assets, high leverage tolerance), but execution risk has risen meaningfully due to right-of-way (ROW), compressed timelines, and equipment supply constraints. POWERGRID remains the reference operator-developer with ~99.8% availability and a dominant position in TBCB (tariff-based competitive bidding) with ~47% cumulative ISTS-TBCB tariff market share since inception, while rapidly scaling its TBCB platform and adjacent businesses (telecom, consultancy, smart metering, grid stability solutions).

A. Industry Overview & Market Landscape

What The Industry Is

Power transmission moves electricity from generation to distribution/load centers through high-voltage networks (AC and DC) consisting of lines, substations, transformation capacity (MVA), reactive power assets, and protection/telecom systems. In India, transmission projects fall into:

• ISTS (Inter-State Transmission System): backbone grid connecting states/regions, largely under
