The Contradiction in One Line: Tata Power reported 9M FY26 PAT at ₹3,702 crore (+7% YoY) while its ROCE sits at 10.8% — barely above the cost of capital. They’re investing ₹10,000 crore per quarter in capex to build 5+ GW of renewable capacity annually. The stock trades at 31.7x earnings. Meanwhile, India’s power demand is rising at single-digit rates, their coal plant is offline, and regulatory asset accounting is doing more heavy lifting than actual operational excellence. This is not Castrol. This is the power sector’s “busy, therefore valuable” play.
02 — Introduction
The Power Company That Needs Itself To Fix India’s Power Problem
Tata Power is India’s largest vertically-integrated power company. And by “vertically-integrated,” we mean: they generate electricity (coal, hydro, renewable), transmit it across 4,633 circuit kilometers, distribute it to 12.5 million consumers in Delhi, Odisha, and Mumbai, manufacture solar panels at 4.5 GW capacity, build rooftop solar systems, operate EV charging stations, and somehow found time to invest in Bhutanese hydropower. That’s not a company. That’s a state trying to privatize itself.
The last three years tell two stories. Revenue grew 15% compounded. Profit grew 21% compounded. But return on invested capital is 10.8%, which means they’re earning barely more than their debt costs. The stock is up 28% over five years, compounded. But if you bought at the 2021 peak, you’re still down. And the dividend yield is 0.60% — which raises the eternal question: why hold this stock if growth is slowing and income is negligible?
Q3 FY26 gave us some answers. PAT of ₹1,194 crore was buoyed by regulatory true-up orders at their Delhi distribution arm (TPDDL), which added ₹344 crore in profit for the quarter. Manufacturing at their solar plant turned a corner with 154% year-on-year profit growth. And their Odisha distribution turnaround is now translating into cash — ₹800 crore in a single quarter. But Mundra, their flagship coal plant, remains offline. And management won’t say why.
Welcome to the power sector’s big, messy, ambitious reality. Where growth matters less than regulatory largesse, and execution competes with government cooperation.
Concall Highlight (Feb 2026): “Highest ever revenue in nearly two decades for Q4 CY25.” Wait—that’s Castrol. For Tata Power, the line was: “Mundra arrangement… on all the issues… except one point.” That one point is apparently classified information from the government.
03 — Business Model: What The Heck Are They Doing?
Generation, Transmission, Distribution, Manufacturing, Rooftop, EV Charging, And Somehow, Still Growing
Tata Power’s business is split into four segments, and it’s genuinely hard to know where to start:
Transmission & Distribution (62% of 9M FY26 revenue): They operate transmission lines across 6 states and distribution in Mumbai (0.5% AT&C loss, meaning they’re world-class at not losing power to theft or technical failure), Delhi via TPDDL (5.6% losses, improving), Odisha (four separate discoms), and Ajmer. Total: 12.5 million retail consumers. This is the cash machine with regulatory pricing. Bad returns, good stability.
Thermal & Hydro (24% of revenue): They own 9,300+ MW of thermal capacity across coal, gas, and oil, plus 880 MW of hydro. Mundra is their flagship imported-coal plant and was running beautifully until it wasn’t. Plant load factors range from 44% (hydro) to 74% (non-Mundra thermal). Economics are hurt by coal inflation, grid curtailment, and merchant power oversupply.
Renewables (13% of revenue): 5,384 MW across solar and wind. But here’s where it gets weird: they’re executing 2.7 GW of renewable capacity in FY26 (including third-party EPC), while simultaneously expanding their own manufacturing. Solar cell capacity is 4.5 GW (with 300 MW coming Q4). Solar module capacity is 4.9 GW. They’re essentially building the grid and the equipment to power it.
Others (1% of revenue): Rooftop solar, EV charging (1.3+ lakh stations), project management, and various adjacent bets.
Transmission Network4,633Circuit Km
Distribution Customers12.5Million
Renewable Capacity5,384MW
Solar Module Capacity4,982MW
The Capex Reality: They plan to spend ₹10,000 crore per quarter (₹40,000 crore annually) on capital projects. For perspective, that’s ₹2,400 crore more per year than Castrol’s entire revenue. This is not a mature, cash-returning business. This is growth capex at a scale that demands multiple years of earnings just to cover.
💬 Here’s a real question: If 10.8% ROCE barely covers cost of capital, why is Tata Power spending ₹40,000 crore per year on new capacity? Hope for better returns in the future, or regulatory duty? What do you think?

The Real Story Behind the Numbers: Revenue fell 9.4% YoY because Mundra was offline for 6 months, costing ~₹800 crore in lost capacity charges. But PAT was essentially flat because TPDDL (Delhi distribution) received a regulatory true-up order worth ₹344 crore PAT (₹460 crore EBITDA) in Q3. Without that one-time regulatory gift, PAT would have fallen ~30%. OPM improved because other segments (especially manufacturing) turned profitable. So the headline looks OK, but operational de-growth is being masked by regulatory windfall accounting.
