1. At a Glance
Tata Power reported consolidated revenue of ₹19,051 Cr for the quarter ended June 2026, up 5.6% from ₹18,035 Cr a year earlier. Operating profit was ₹3,860 Cr against ₹3,565 Cr, an 8.3% rise, with operating margin at 20%. Net profit came in at ₹1,401 Cr versus ₹1,262 Cr, up 11.0%; of that, ₹1,176 Cr is attributable to owners of the company, giving EPS of ₹3.68 against ₹3.32.
The quarter’s largest single number is not on the income statement. Capital expenditure was ₹5,375 Cr — described by the company as its highest ever quarterly capex. Net debt moved from ₹56,122 Cr at end-Q4 FY26 to ₹61,238 Cr, with net debt to equity at 1.25x.
The Mundra plant, which supplied no power between July 2025 and March 2026 while overhauling, ran through this quarter under Section 11 directions at 94% reported availability, billing on supplementary-PPA terms. The Gujarat SPPA was executed in March 2026; approvals from the remaining procurers are in progress, and the Section 11 permission runs to 30 September 2026.
TP Solar produced a record 1,001 MW of modules and lifted PAT to ₹371 Cr from ₹96 Cr. The rooftop business billed 371 MWp against 270 MWp. The third-party solar EPC business went the other way: revenue from large projects and group captive fell 71% to ₹411 Cr, with EBITDA at negative ₹57 Cr.
Sequentially, the picture is stranger — and the March quarter is where it gets interesting.
2. Introduction
Formed in 1915, Tata Power sits across the entire electricity value chain: generation, transmission, distribution, coal mining, solar manufacturing, EPC and power trading. Total capacity stood at ~16.8 GW at Q1 FY27, with 8.8 GW thermal and the balance across solar, wind, hydro and waste-heat recovery. Distribution reaches 13.2 million customers across Mumbai, Delhi, Odisha and Ajmer. Tata Sons holds 45.21%.
The last few years have been an exercise in rebuilding the mix. Renewables contributed 22% of FY26 segment terms versus 14% in FY25; thermal and hydro fell to 12% from 24%. The company targets at least 70% clean capacity by 2030 and 100% by 2045 as thermal PPAs expire.
Recent activity has been dense. In April 2026 TPREL approved a photovoltaic ingot and wafer facility of 10 GW across two phases, an investment of up to ₹6,500 Cr. In May, Bhutan and the World Bank signed $515 million of financing for the 1,125 MW Dorjilung hydro project, in which Tata Power holds 40%. In July, SECI awarded a letter of award for 324 MW / 2,592 MWh of pumped storage service over 40 years at ₹351.3 Cr annually. TPREL commissioned the 100.8 MW Jewali wind project in Maharashtra in early July.
Ind-Ra affirmed the issuer rating at IND AA+/Stable in July 2026, taking a fully consolidated view and citing the regulated nature of distribution, transmission and generation assets. The agency also lists a weakness: pending resolution for the Mundra plant.
Outstanding since 2023 is an arbitration matter. The Singapore International Arbitration Centre found the company in breach of non-disclosure agreements with Kleros Capital Partners and, in 2025, awarded damages of USD 490.32 million plus interest and costs. The company has appealed to the Singapore International Commercial Court; hearings are complete and the order is reserved. No provision has been recorded. The auditors flagged it as an emphasis of matter without modifying their conclusion.

3. Business Model: WTF Do They Even Do?
Tata Power sells electrons four different ways and hopes you don’t notice they’re four different companies wearing one coat.
The regulated coat. Transmission and distribution — 65% of FY26 revenue — is the boring bit that pays for everything else. 5,562 Ckm of operational transmission lines, 13.2 million distribution customers, and a return set by regulators rather than by anyone’s negotiating skill. AT&C losses in Mumbai operations were 0.6% in FY26; TPDDL 5.4%; Odisha 15.5%. Odisha, acquired in 2021, is where the improvement work happens; Mumbai is already so close to zero that further progress requires inventing a new decimal place.
The renewable coat. 6,734 MW of RE capacity, up 1,100 MW year on year. Plus a 4.9 GW solar cell plant and a 4.9 GW module plant, plus a rooftop business ranked India’s number one for eleven straight years, plus 5,970 public EV charging points across 717 cities. The manufacturing plant sells to itself and to strangers — 63% of module sales in Q1 went external.
The thermal coat. 8.8 GW, including Mundra’s 4,150 MW, Trombay’s 930 MW, Maithon’s 1,050 MW and a 20% slice of Prayagraj. Mundra runs on imported coal, which is why Tata Power also owns 30% of Kaltim Prima and 26% of BSSR in Indonesia. The company is, structurally, hedged against itself: when coal is expensive the mines earn and the plant suffers, and vice versa. Management describes the mine
