NTPC Limited just dropped a number that stops you in your tracks: ₹17 lakh crore over the next decade. That’s roughly ₹7 lakh crore in the first five years alone, spanning thermal, gas, nuclear, and storage technologies. Chairman Gurdeep Singh laid this out at the India Energy Summit, framing it as a response to unprecedented domestic power demand. But here’s the thing—this isn’t just about building more plants. It’s about a fundamental shift in how India uses electricity, when it uses it, and where that power comes from. Let’s break down what’s actually happening beneath the headline.
For years, peak demand in India was a sprint—maybe 4 hours in the evening. Not anymore. Singh says that window has shrunk to about 3.5–3.7 hours right now, but the real story is how it’s expanding to 10–12 hours. That’s a massive structural change.
What’s driving this? It’s a cocktail of factors. El Niño has messed with weather patterns, pushing up cooling requirements. The economy is expanding, lifting baseline consumption. Then there’s the new kid on the block: artificial intelligence and data centers. These facilities run 24/7 and guzzle power. Add in industrial growth, and you get a load profile that doesn’t just spike—it stays high for longer.
This shift hits NTPC Limited right where it hurts. The company operates about 91 GW of capacity, with another 37 GW under construction. When peaks last longer, you can’t just rely on solar, which disappears after sunset. You need firm power. That’s why coal-based generation surged 18% in the current month. Coal still supplies about 70% of India’s energy, and it’s the backbone that keeps the lights on when the sun goes down.
But this comes with a cost. Plant load factor (PLF) has dropped to around 77% from over 80% a few years ago. Why? Because plants back down during the day when solar floods the grid, then ramp up hard in the evening. That cycling burns efficiency. Backing down supercritical units below their optimal level reduces output per unit of fuel. It’s like driving a car in stop-and-go traffic instead of on the highway. You get where you’re going, but you burn more fuel and wear out the engine faster. Transcript +1
Here’s how the big number breaks down. The plan is back-loaded, not front-loaded. The first five years account for about ₹7 lakh crore, or roughly 41% of the total. The heavier lifting—about ₹9.63 lakh crore—comes in the second half (FY33–FY37), when nuclear and storage take center stage. Transcript
By technology, the mix is telling. Renewables get the largest slice at 43% (₹7.24 lakh crore). Nuclear is second at 27% (₹4.63 lakh crore). Thermal gets 18% (₹3.09 lakh crore), while hydro and pumped storage take 8%, and battery storage just 3%. Investor Presentation
This allocation reflects a delicate balancing act. Coal is still king today, but its share of the portfolio is set to fall from 82% to 56% by FY32 and 39% by FY37. In absolute terms, coal capacity keeps growing—from about 66 GW now to 77 GW under the plan, with a 17 GW pipeline under construction. But the intensity of coal additions is declining. The question isn’t thermal versus renewable anymore, as Singh put it. It’s whether you can get power on demand that’s also affordable. Transcript +1
NTPC Limited aims to build 30 GW of nuclear capacity by 2047, contributing about 30% of India’s 100 GW national goal. That sounds impressive, but the timeline is back-ended. The company expects only about 1 GW by 2032 and 6 GW by 2037. Most of the heavy lifting happens after that. Investor Presentation
The reference project is Mahi Banswara in Rajasthan—a 2,800 MW plant being developed through ASHVINI, a joint venture with NPCIL. The investment is about ₹42,000 crore, implying roughly ₹15 crore per MW. First concrete is expected by August 2027, with the first unit synchronizing in November 2032. That’s a six-year wait before a single unit of power flows. Other +1
Nuclear brings firm, clean baseload power—exactly what a grid with 10–12 hour peaks needs. But it’s capital-intensive with a long gestation period. Capital sits unproductive for years, which can pressure return on capital employed (ROCE). The company hasn’t disclosed a direct nuclear-versus-thermal cost comparison, but the trade-off is clear: nuclear pays off over decades, while thermal delivers returns sooner. Investor Presentation
Clearances are another bottleneck. Three sites have been submitted to the Department of Atomic Energy and the Atomic Energy Commission. The SHANTI Act, 2025 opened the door to private and foreign investment, but detailed rules were still in draft as of August 2026. Until those gates open, nuclear projects face regulatory and execution uncertainty.
When peaks stretch into double-digit hours, storage becomes non-negotiable. But NTPC Limited isn’t putting all its chips on lithium-ion. The company is prioritizing non-lithium alternatives—pumped storage, vanadium flow batteries, and CO2 batteries—to curb import dependence on critical minerals like lithium and cobalt.
The headline project is a 160 MWh CO2 battery at Kudgi, built with Italy’s Energy Dome and Triveni Turbine. It uses a thermodynamic cycle with CO2 as the working fluid, offering a claimed life of over 25 years, 100% depth of discharge, and no critical minerals. Commissioning is expected around November 2026. If it works, NTPC plans to replicate it elsewhere. Transcript
Then there’s the 100 MWh vanadium flow battery project at Khavda Solar Park in Gujarat, awarded to Bondada Engineering. Vanadium flow batteries also boast long lifetimes and minimal degradation, making them suitable for long-duration storage.
Pumped storage remains the least-cost option in India today. The NTPC Group is working on about 18,010 MW of pumped storage projects, including 750 MW already commissioned at THDC Tehri. Management estimates storage costs at around ₹3.50–4.00 per unit, with an all-in price of ₹7.25–8.25 per unit including the price adder. Transcript +1
Lithium-ion isn’t being ignored—far from it. The company has a 38.9 GWh battery storage portfolio, including a 30.4 GWh non-solar-hour pipeline. But non-lithium is the strategic bet for the long haul, especially if peak durations keep expanding. The risk is technological: CO2 and vanadium flow are first-of-a-kind at this scale in India. Success isn’t guaranteed, and costs are still opaque. Transcript
NTPC Limited is also rethinking how it sells power. In October 2026, it invited industries to take a 26% equity stake in co-generation projects that supply both steam and electricity. These projects integrate coal, renewables, and battery storage, offering long-term contracts to industrial consumers. Co-generation improves fuel efficiency by producing heat and power together, and an industry expert noted it could help avoid certain open-access surcharges, potentially lowering costs.
On the green fuels front, the company is developing a massive green hydrogen hub at Pudimadaka near Visakhapatnam, spanning 1,200 acres. The hub aims to produce over 2.5 million tonnes of green chemicals annually, including green ammonia and methanol, backed by 7 GW of renewable energy. A 20–25 km pipeline from the Simhadri power station will supply CO2 as feedstock for methanol production. Investor Presentation
Offtake is the critical challenge. NTPC is in talks with buyers in Japan, South Korea, and Germany for export deals. It has already signed a 70,000 tonnes per annum green ammonia purchase agreement under SECI’s SIGHT scheme and an MoU with Japan’s ENEOS for green methanol. But as Singh stressed, green hydrogen must move from pilot to dependable demand to become a viable business. Transcript
So, how does NTPC Limited pay for all this? Management says funding will come mainly from internal accruals and debt, with a dividend payout ratio of 36–40%. The company’s weighted average borrowing cost has fallen to 5.98% in FY26 from 6.61% the previous year, and its debt-to-equity ratio stands at about 1.32. Domestic credit ratings are AAA (CRISIL, ICRA, CARE), while international ratings (S&P, Moody’s, Fitch) are investment-grade and aligned with sovereign ratings. Transcript +2
But the scale of the plan is staggering. FY26 operating cash flow was about ₹50,902 crore, while group capex was around ₹49,000 crore. The planned FY28–32 spend averages about ₹1.19 lakh crore per year—more than double current cash generation. That implies substantial external borrowing. Net debt has already crept up from about ₹1.81 lakh crore in FY22 to ₹2.04 lakh crore in FY26. Interest coverage has weakened to about 2.09x in FY26, though Q1 FY27 recovered to 3.25x. Transcript +1
On returns, the CMD says regulated returns on new projects are about 15.5% after commissioning, or roughly 12–13% in practice. All new projects have power purchase agreements (PPAs). Historical ROCE has hovered around 9–10%, while ROE has climbed to about 14% in FY26. Nuclear and green hydrogen are capital-intensive with long payback periods, which could temporarily pressure ROCE before assets start earning. Thermal projects with PPAs convert to cash sooner. Transcript +1
Dividends have risen from ₹7.15 per share in FY22 to ₹8.85 in FY26 (or ₹9.00 on the company’s basis). Management intends to keep dividends rising, but the heavy capex program means retained earnings will be crucial. The mix of long-cycle projects (nuclear, storage, hydrogen) versus shorter-cycle thermal will shape cash flow and dividend capacity over the next decade. Transcript
NTPC Limited isn’t just building power plants anymore. It’s reshaping its portfolio for a world where peak demand lasts half the day, AI drives consumption, and decarbonization is non-negotiable. The ₹17 lakh crore plan is a bet on coal as the bridge, nuclear as the long-term anchor, and storage as the enabler. It’s a bold, expensive, and risky transformation—but one that India’s energy future likely depends on.
