Company Overview
Power Grid Corporation of India — India's Transmission Backbone
Power Grid Corporation of India Limited (NSE: POWERGRID) is a Maharatna Central Public Sector Enterprise (CPSE) and India's largest electric power transmission company. The company owns and operates the Inter-State Transmission System (ISTS), covering over 1,73,000 circuit kilometres of high-voltage transmission lines and over 280 substations. Power Grid is a pure-play transmission utility — it does not generate or distribute electricity but provides the critical infrastructure to evacuate power from generators to distribution companies.
Revenues are earned through long-term (35-year) Transmission Service Agreements (TSAs) under the Regulated Tariff Mechanism (RTM) and, increasingly, under Tariff Based Competitive Bidding (TBCB). The business model provides exceptional earnings predictability — with stable, regulated returns on a growing Regulated Asset Base (RAB). Government of India holds 51.34% of the company.
Business Segments (FY26)
| Segment | FY26 Revenue (Consol.) | Description & Trend |
|---|---|---|
| Transmission | ~₹43,250 Cr | Core regulated tariff business — stable, earns regulated returns on capitalized assets over 35-year TSA life. RTM model shifting to TBCB for new projects. |
| Consultancy | ₹2,347 Cr | Fastest-growing segment. Surged +437% from ₹536 Cr (FY23) to ₹2,347 Cr (FY26). Domestic system strengthening + international projects in 25+ countries. |
| Telecom | ₹1,195 Cr | Powergrid Teleservices Limited (100% subsidiary, spun off Oct 2023). Dark fibre leasing, data services on grid backbone. Steadily growing. |
Structural Note: Standalone telecom revenue disappeared from FY24 onwards when the business was transferred to the 100% subsidiary Powergrid Teleservices Limited (PGTSL). The consolidated books show the full picture. Natural revenue dips in older transmission projects (post-12-year mark, when depreciation recovery drops from 5.28% to ~1.2%) are actively offset by newly capitalised projects.
Executive Summary
Investment Thesis
Power Grid earns stable, regulated returns on capitalized transmission assets over 35-year TSAs. A massive multi-year capex programme (₹32,000 Cr in FY26, stepping up to ₹37,000 Cr in FY27 and ₹45,000 Cr in FY28) directly expands the RAB, which is the primary driver of future earnings growth.
Management estimates a ₹7.9 lakh crore transmission investment opportunity through 2035, expandable to ₹15 lakh crore with international and cross-border HVDC interconnections. Works in Hand of ₹1.7 lakh crore (81% from TBCB wins) underpins a 3–5 year capex runway with high revenue visibility.
India's 500 GW non-fossil energy target by 2030 requires massive new transmission infrastructure to evacuate solar/wind from resource-rich zones to urban load centres. Power Grid is building Green Energy Corridors and 765kV EHVAC/HVDC systems — a direct beneficiary of India's energy transition mandate.
Consolidated consultancy revenues surged nearly +337% from ₹537 Cr (FY23) to ₹2,347 Cr (FY26). International footprint now spans 25+ countries. This higher-margin segment is becoming a meaningful earnings contributor beyond the core regulated business.
New projects are increasingly awarded under TBCB (81% of current backlog). Unlike RTM where returns are pegged to project cost, TBCB allows Power Grid to retain efficiency gains — but also exposes it to competition. Power Grid's scale, balance sheet, and execution track record are durable competitive moats.
Dividend yield of 3.1% at CMP. DPS stable/growing. FY26 dividend outflow: ₹8,371 Cr (declining from ₹11,219 Cr peak in FY24 as internal capex use increases). Strong operating cash flows (₹44,097 Cr in FY26) comfortably cover dividends and capex.

| Dividend Payout | 67% | 67% | 54% | 79% | 65% | 65% | 65% |
* FY26 OPM down to 75% due to a one-off exceptional cost item; underlying OPM ~84% historically and expected to revert in FY27E. Revenue growth appears muted (2–6%) because the RTM model sees natural decline in aging project revenue. Growth accelerates as new capex projects are commissioned into the RAB.

Operating cash flows are massive (~₹44,097 Cr in FY26) boosted by ~₹13,000 Cr non-cash D&A add-backs. The re-leveraging is deliberate — ₹28,166 Cr of new non-current borrowings raised in FY26 to fund the ₹1.7 lakh Cr backlog. Debt management risk is low given AAA-rated PSU status and regulated revenue coverage.
Valuation Frameworks
Primary: EV/EBITDA Model
EV/EBITDA is the primary valuation method for Power Grid because it is a capital-intensive utility business where earnings are driven by large transmission assets and regulated returns. Significant fixed assets, high depreciation, and long-term debt make EBITDA a more reliable indicator of operating value than PAT. EV/EBITDA is also widely used globally for utility and infrastructure companies, enabling meaningful peer comparison.
| Metric | FY24A | FY25A | FY26A | FY27E | FY28E | FY29E |
|---|---|---|---|---|---|---|
| Revenue (₹ Cr) | 45,843 | 45,792 | 46,733 | 48,602 | 51,518 | 54,610 |
| Growth | +0.6% | -0.1% | +2.1% | +4.0% | +6.0% | +6.0% |
| OPM | 86% | 85% | 75%* | 84% | 84% | 84% |
| EBITDA (₹ Cr) | 39,425 | 38,923 | 35,050 | 40,826 | 43,276 | 45,872 |
| Net Debt (₹ Cr) | 128,000 | 134,000 | 140,000 | 147,000 | 154,000 | 162,000 |
| EV/EBITDA | 9.0× |

| EV | ₹5,27,528 Cr |
| Net Debt | ₹1,62,000 Cr |
| Equity Value | ₹3,73,528 Cr |
| Shares | 930 Cr |
Revenue growth rationale: Low near-term growth (4–6%) reflects natural RTM aging revenue decline offset by newly capitalised projects. Growth accelerates as the ₹1.7 lakh Cr backlog commissions into the RAB over FY27–FY29. FY26 OPM of 75% is a one-off exceptional cost item; ~84% OPM historically is the normalised base for projection.
Secondary: P/E Model (ROE × BVPS)
| Metric | FY22 | FY23 | FY24 | FY25 | FY26 | FY27E | FY28E | FY29E |
|---|---|---|---|---|---|---|---|---|
| EPS (₹) | 18.09 | 16.58 | 16.74 | 16.69 | 17.13 | 18.25 | 20.53 | 23.15 |
| ROE | — | — | — | — | — | 16% | 17% | 18% |
| BVPS (₹) | — | — | — | — | — | 114.05 | 120.78 | 128.62 |
| P/E (Now Case) | — | — | — | — | 16.6× | 16.6× | 17.0× | 17.0× |
| Price (Now Case) | — | — | — | — | 284 | 303 | 349 | 394 |

| Price (Bull) | — | — | — | — | — | 310 | 370 | 440 |
EPS has been remarkably stable (₹16.58–₹17.13 over FY23–FY26) as the RAB model buffers earnings volatility. The growth inflection to ₹18–23 in FY27–29E reflects new project commissionings. The ROE × BVPS EPS projection (retention ratio ~35% at 65% payout) suggests improving shareholder returns as capex turns productive.
Tertiary: Dividend Discount Model (DDM)
DDM is a particularly relevant secondary lens for Power Grid given its high dividend payout (~54–79%), predictable regulated earnings, and stable dividend history. The company is essentially a dividend-growth stock with RAB-linked earnings expansion.
| Year | FY23A | FY24A | FY25A | FY26A | FY27E | FY28E | FY29E |
|---|---|---|---|---|---|---|---|
| EPS (₹) | 16.58 | 16.74 | 16.69 | 17.13 | 18.25 | 20.53 | 23.15 |
| Payout Ratio | 67% | 67% | 54% | 79% | 65% | 65% | 65% |
| DPS (₹) | 11.11 | 11.22 | 9.01 | 13.53 | 11.86 | 13.35 | 15.05 |
| Ke (Cost of Equity) | 10% |
| Terminal Growth (g) | 5% |
| Terminal Dividend (FY29E) | ₹15.05 |
| Terminal Value PV | ₹301 |
| Explicit Period PV | ~₹35 |
| DDM Price | ~₹315 |
DDM Sensitivity (Terminal Price)
| g \ Ke → | 9.0% | 9.5% | 10.0% | 10.5% | 11.0% | 11.5% | 12.0% |
|---|---|---|---|---|---|---|---|
| 4.0% | 313 | 285 | 261 | 241 | 224 | 209 | 196 |
| 4.5% | 349 | 315 | 286 | 262 | 242 | 225 | 210 |
| 5.0% | 395 | 351 | 316 | 287 | 263 | 243 | 226 |
| 5.5% | 454 | 397 | 353 | 318 | 289 | 265 | 244 |
| 6.0% | 532 | 456 | 399 | 354 | 319 | 290 | 266 |
At Ke=10%, g=5% (base): DDM = ₹315. At CMP ₹292, the DDM implies a dividend yield play with upside as EPS (and therefore DPS) grows through new RAB commissionings. The DDM naturally underpins the stock's defensive characteristics during equity market volatility.
EV/EBITDA Sensitivity (FY29E Price)
| EV/EBITDA | Price (₹) | vs CMP (₹292) |
|---|---|---|
| 7.0× | 171 | -41.4% |
| 8.0× | 220 | -24.7% |
| 9.0× | 270 | -7.5% |
| 9.5× | 294 | +0.7% |
| 10.0× | 319 | +9.2% |
| 10.5× | 344 | +17.8% |
| 10.8× | 358 | +22.6% |
| 11.0× | 368 | +26.0% |
| 11.5× | 393 | +34.6% |
| 12.0× | 418 | +43.2% |
| 12.5× | 442 | +51.4% |
The stock currently trades at ~9.5× FY29E EBITDA (implied by CMP). Any re-rating toward 10.8–11.5× (in line with utility sector peers globally) provides 23–35% upside. The RAB growth story supports EV/EBITDA multiple expansion as new commissionings reduce execution risk.
Risk Factors
Key Risks & Mitigants
| Risk | Description | Severity | Mitigation |
|---|---|---|---|
| RTM Revenue Aging | As older projects complete 12 years of life, depreciation recovery drops from 5.28% to ~1.2% and interest compensation drops near zero — causing ~9% natural revenue decline for those specific assets | Medium-High | Actively managed: new TBCB projects commissioned from ₹1.7 lakh Cr backlog directly offset aging RTM revenue. Consultancy growth provides supplementary revenue |
| Re-leveraging Risk | Current borrowings nearly doubled (₹14,626 Cr → ~₹26,937 Cr). Total debt rising aggressively to fund capex step-up to ₹45,000+ Cr per year | Medium | AAA-rated PSU — lowest borrowing cost; stable regulated revenues comfortably cover debt service; operating cash flows ₹44,097 Cr cover new capex from internal accruals + 80:20 debt-equity mix |
| TBCB Competition | Private sector players (Adani Transmission, Sterlite Power, Torrent Power) aggressively bidding for TBCB projects. Power Grid's ~81% share of current backlog (₹1.37 lakh Cr TBCB) could face pressure | Medium | Scale, balance sheet, execution track record, and technology advantage (765kV HVDC) are durable moats. GoI policy preference for POWERGRID as the national carrier also provides structural support |
| Regulatory / Tariff Risk | CERC revises tariff regulations every 5 years; the FY24–29 block is governed by the newly notified CERC 2024 regulations. Any reduction in allowed return on equity would impact earnings | Low-Medium | CERC 2024 provides 5-year regulatory certainty; historically CERC has maintained a fair return on equity for PSU utilities; government ownership provides additional political floor |
| Project Execution Delays | Clearances, land acquisition, and right-of-way issues can delay project commissioning — delaying RAB addition and revenue recognition | Medium | Sovereign execution muscle and established clearance relationships; proactive land acquisition under new frameworks; track record of consistent annual network additions (4,000–7,500 ckm) |
| Interest Rate Risk | New borrowings priced at prevailing AAA PSU bond rates. Rising interest rates increase funding costs for new capex projects | Low | Revenue is indexed to debt costs under RTM — CERC allows pass-through of normative interest; TBCB projects evaluated on post-financing DSCR; declining RBI rate cycle in FY26 is supportive |
