Tata Power — record profits with the big plant switched off

The State of Play

Tata Power closed FY26 with its first-ever full-year profit above ₹5,000 crore — ₹5,118 crore on the screener tape — while its single largest power plant, the 4 GW Mundra coal station, sat idle for nine of those twelve months. The company spent the year promising ₹25,000 crore of capex and delivering roughly ₹13,000 crore, promising 2.6 GW of its own renewable capacity and delivering about 1 GW, and promising a Mundra contract “within August” that finally closed with Gujarat the following May. And yet the profit streak — 24 consecutive quarters of PAT growth, by management’s count — stayed intact, carried by three businesses that barely registered three years ago: solar manufacturing, rooftop solar, and the Odisha distribution companies.

The Company

Tata Power is India’s largest vertically-integrated private power company — it generates electricity (coal, hydro, solar, wind), moves it across transmission lines, and sells it to homes in Mumbai, Delhi and Odisha. On top of that legacy stack it has built a cluster of newer businesses: a 4.55 GW solar cell and module factory, the country’s largest rooftop solar installer, EV charging, and a renewables developer with 5.5 GW under construction.

The promoter — Tata Sons — has held exactly 46.86% through every quarter for three years; not a share bought or sold. The drift beneath that is institutional: domestic funds have climbed from 14.59% to 17.98% of the register between June 2023 and March 2026, almost exactly mirroring the public’s decline from 28.48% to 24.81%. Retail shareholder count has fallen four straight quarters. The market pays 34x earnings and 3.3x book for a business earning roughly 10% on equity — which is the bet in one line: that the new businesses change what kind of company this is before the arithmetic catches up.

The annual reports tell the same story as a capital-allocation ledger. Consolidated capex ran ₹7,656 crore in FY23, nearly doubled to ₹13,333 crore in FY24 (about 65% into renewables), then ₹17,273 crore in FY25 — of which 95% went to renewables and the wires business, with thermal down to ₹728 crore. Borrowings went from ₹53,689 crore (FY24) to ₹76,141 crore (FY26); free cash flow was negative ₹4,357 crore and then negative ₹7,677 crore in the last two years. A utility rebuilding itself on borrowed money, on purpose.

The Story So Far

August 2025 — Q1 FY26: “the SPPA will be finalized within August”

The year opened with an oddity: all-India power consumption fell about 1.3% in the June quarter — “we have not seen [that] for at least last 5–6 years,” CEO Praveer Sinha told analysts, blaming a monsoon that arrived mid-May. Mundra was on maintenance shutdown, available but barely dispatched, and management made the year’s central promise: a supplementary power purchase agreement (SPPA) with its five procurer states — the contract that would finally fix Mundra’s broken economics and serve as the template “for the next 13 years up to 2038” —

“will be finalized within August.” — Dr. Praveer Sinha, CEO & MD

The plant would not run until it was signed. With it came the year’s other commitments: ₹25,000 crore of capex (₹3,700 crore spent in Q1), roughly 1,600 MW of own utility-scale renewables over the next three quarters, “more than 2 gigawatt” of total commissioning for the year. Rooftop was scaling from 8,000 units a month to 20,000, guided to 40–50,000 “later this year.”

The sharper analysts were already probing the soft spots. Ambit’s Satyadeep Jain asked why Tata’s solar commissioning lagged the industry’s surge; Sinha answered with a year-on-year doubling (350 MW → 652 MW) rather than the relative question. Nuvama asked what Mundra costs annually while idle; no number was given.

November 2025 — Q2 FY26: the target slips, the streak holds

By November the August promise had quietly become a November one — the Gujarat SPPA was now “in the last stage and hopefully maybe within this month.” Mundra had been shut the entire quarter. And the renewables target was formally walked back: the original 2.6 GW of own utility-scale for FY26 was now ~1.5 GW, recast as a deferral —

“Whatever will get missed out in this financial year, we will try to complete it within the next financial year.” — Dr. Praveer Sinha

The actual own-build number for the half: 205 MW, in a year the industry commissioned 27–28 GW. Management’s explanation was that the first half went to finishing third-party EPC commitments.

What kept the call upbeat was everything else. EBITDA crossed ₹4,000 crore in a quarter for the first time, PAT grew 14% — the 24th straight quarter of growth — with the loss-making Mundra cluster (~₹360 crore drag) fully absorbed. The new engines revved: Odisha discoms’ PAT up 362%, the cell-and-module plant up 262%, rooftop up 390% with its first ₹1,000-crore quarter. The board approved a second Bhutan hydro project (1,125 MW Dorjilung, 40% stake, no recourse to Tata Power), and a 10 GW ingot-and-wafer plant was “in principle decided,” with numbers promised “in the next two months.”

The uncomfortable exchange came from JP Morgan’s Atul Tiwari, who noted net debt had risen about ₹10,000 crore in a half-year against ₹7,300 crore of capex — a gap management never reconciled, offering instead a soft “around 4x” net-debt-to-EBITDA guardrail. Screener’s quarterly tape shows what the monsoon did: sales of ₹15,545 crore in the September quarter, falling to ₹13,948 crore in December — the weakest top line since March 2023.

February 2026 — Q3 FY26: a beat with an asterisk

Q3 EBITDA came in at ₹3,913 crore, up 12%. Then Axis Capital’s Sumit Kishore did the bridge arithmetic out loud: a one-time Delhi regulatory true-up — an order letting the Delhi discom recover old FY22-23 dues, worth ₹460 crore at the EBITDA line — explained essentially the entire year-on-year increase, and it hadn’t been called out. Management’s counter was fair as far as it went: the prior-year quarter had ~₹300 crore of Mundra EBITDA that this year lacked, so the one-off was substituting for an absence. The 9-month Mundra hit, extracted under questioning: roughly ₹800 crore at the PAT level.

The Mundra promise moved again — one point still open with Gujarat, to be closed “in the next 2–3 weeks,” restart “maybe by the end of this month.” This time it largely held: the plant came back under Section 11 (the government’s emergency-dispatch provision), billing per the not-yet-fully-signed SPPA terms.

The new businesses kept compounding — manufacturing 9M PAT up 154% with a 28% quarterly EBITDA margin, rooftop crossing 1 GW in nine months, Odisha 9M PAT at ₹505 crore versus ₹164 crore. Asked by Goldman’s Nikhil Bhandari how much of that margin was policy-built (captive cells under domestic-content rules) and how durable it was, Sinha offered: “this will be much, much better going forward… It will not become worse.” Not a number. Sinha closed the call nudging analysts to give the distribution business more weight in their models, and renewables — “too many players and… margins are a challenge” — less. From a company spending most of its capex on renewables, it was a striking aside.

May 2026 — Q4 FY26: the record, and the reconciliation that didn’t come

The year ended with the headline management wanted: FY26 PAT above ₹5,000 crore for the first time, EBITDA of ₹16,090 crore up 11%, “in spite of the fact that Mundra did not operate for 9 months.” The Gujarat SPPA was finally concluded — nine months after “within August” — with the remaining four states promised in “4 to 6 weeks.” The full-year segment tallies confirmed the new-engine story: manufacturing PAT ₹857 crore (doubled), rooftop ₹499 crore, Odisha ₹809 crore versus ₹439 crore.

The asterisks sat in plain view for anyone reading the notes. Q4’s ₹1,416 crore record PAT carried roughly ₹1,773 crore of other income and a ₹250 crore non-cash deferred tax asset; operating profit actually fell that quarter, with margin dropping from 22% to 17%. Delhi’s prior-period regulatory clearances contributed ₹783 crore across FY26, versus ₹333 crore the year before — and management declined to say what FY27’s number might be.

The hardest exchange was again Sumit Kishore on capex. FY26 came in around ₹13,000 crore against guidance he insisted — citing management’s own November presentation — was ₹25,000 crore. Sinha countered that the guidance had been “about ₹22,000 crores.” The two figures were never reconciled; the ~40%+ shortfall was framed as “phasing” caused by transmission and right-of-way delays, “not that these will not come.” The same ₹25,000 crore was then re-guided for FY27, and again for FY28.

Strategy, meanwhile, visibly shifted at the edges: future renewable bids will be hybrid-plus-storage rather than pure solar or wind; the 10 GW wafer plant got a rationale (domestic-wafer rules from June 2028) and a two-phase plan; small modular nuclear reactors (2×220 MW, with NPCIL, three states) entered the deck; and the long-standing refusal of new coal softened to “if the tariff is attractive and it’s a bankable PPA, we’ll definitely look at those.”

Where Things Stand

The pattern across four quarters is consistent: headline delivery, slipped specifics. The PAT streak is real and the new businesses driving it — manufacturing, rooftop, Odisha — are genuinely compounding, large enough now (₹2,100-odd crore of combined FY26 PAT) to absorb a nine-month outage at the company’s biggest plant. But the year’s three concrete promises — the August SPPA, the 2.6 GW build, the ₹25,000 crore capex — landed at May, ~1 GW own, and ~₹13,000 crore respectively, each reframed as deferral rather than miss. The quality of the earnings beat needed analyst excavation twice (the Delhi true-ups in Q3 and Q4, the other-income-heavy record quarter).

The FY27 setup repeats the bet at larger scale: ₹25,000 crore of capex, 2.5 GW of own commissioning using its own cells, Mundra fully contracted, Odisha guided to “peak,” rooftop guided up 50–100%. The balance sheet is the constraint to watch — net debt around ₹56,000 crore at 3.3x EBITDA, free cash flow deeply negative two years running, interest costs grinding up — against returns still near 10% on equity. Management itself put the open questions on the record by declining to answer them: what the SPPA gives away on coal profits, what curtailment costs, how much of the manufacturing margin is policy, and whether Delhi’s regulatory gifts repeat.

The Four Checks

1. Quality and moat. A collection of businesses with very different moats stapled together. The wires-and-discoms core — Mumbai, Delhi, Odisha distribution plus transmission — is a genuine franchise: licensed monopoly infrastructure with regulated returns that nobody can replicate without a government’s permission, and it was the biggest profit driver in FY25 (T&D result up 29%). Around it sits everything contestable: utility-scale renewables, where management itself conceded “too many players and… margins are a challenge”; solar manufacturing, whose 28% margins lean on domestic-content rules management wouldn’t quantify when Goldman asked; and Mundra, a 4 GW coal plant that spent nine months idle waiting for a contract. The licensed core is durable; much of the growth story sits in the crowded part. A real moat, but only over part of the castle.

2. Returns on incremental capital and runway. This is the weak check. ROCE is 10.5% and ROE 10.1%, with the three-year ROE at 10.7% — flat at a level that barely clears a utility’s cost of capital, despite four straight years of record profits. The runway is enormous on paper (₹25,000 crore of capex guided for FY27 and again FY28, India’s electrification as the tide), but runway only matters if the returns are worth redeploying at, and three years of pouring ₹38,000-odd crore into renewables and wires has not moved the return needle. The new engines — manufacturing, rooftop, Odisha, ₹2,100-odd crore of combined FY26 PAT — are compounding fast, but they are still being outweighed by the low-return bulk of the asset base.

3. Capital allocation for the stage. Mixed, and internally consistent at least: management has chosen to reinvest everything and then some. Capex went ₹7,656 → ₹13,333 → ₹17,273 crore over FY23–25 (95% into renewables and wires by FY25, thermal down to ₹728 crore), funded by borrowings rising from ₹53,689 crore to ₹76,141 crore in two years, with free cash flow at negative ₹4,357 and then negative ₹7,677 crore. Dividend payout has held near 20%; no buybacks appear anywhere in the record, and no dilution either — promoter holding frozen at 46.86% throughout. The quibbles are real: reinvesting this hard at ~10% returns is the strategy’s central gamble, the capex guidance missed by 40%+ and was never reconciled, and the deck keeps acquiring new fronts — a 10 GW wafer plant, small modular reactors, a softened stance on new coal — in a business already running 3.3x net debt to EBITDA. Disciplined in form, expansive in appetite.

4. Price. Demanding. As of the June 2026 snapshot, the stock trades at ₹399 — 33.5x earnings and 3.23x book value for a business earning 10.1% on equity, with a 0.63% dividend yield. That is growth-stock pricing on utility returns: the multiple only works if the new businesses lift the blended return on equity well before the borrowing costs and negative free cash flow bite, and the latest record quarter needed ₹1,773 crore of other income to get there while operating profit fell. The market is paying today for a transformation that is real but, on the return numbers, not yet visible.
