NTPC Plans Rs 17 Lakh Crore Expansion as India Seeks More Reliable Power

A Rs 17 Trillion Plan to Meet Longer Hours of Demand

NTPC plans to invest Rs 17 lakh crore, equivalent to Rs 17 trillion, over the next decade as India's largest power producer expands electricity generation, storage and green fuels. Chairman and Managing Director Gurdeep Singh said about Rs 7 lakh crore would be invested in the first five years, alongside a push toward 30 gigawatts of nuclear capacity by 2047.

Speaking at the 20th India Energy Summit 2026, organised by the Indian Chamber of Commerce in New Delhi, Singh described a growing challenge: supplying affordable electricity through longer periods of high demand. Economic growth, cooling systems, artificial intelligence and data centres are adding pressure, while changing weather conditions affect how much power consumers need.

NTPC's expansion targets put numbers behind that challenge. Executives outlined plans for a capacity portfolio of 150 gigawatts by fiscal 2032 and 250 gigawatts by fiscal 2037, compared with about 91 gigawatts operating today. A gigawatt is 1,000 megawatts, a unit used to describe how much electricity a power station can produce at a given moment.

Singh said the central issue was dependable supply at a price consumers could afford:

The real question is whether we are able to get the power on demand and that will be also affordable.

NTPC intends to expand coal generation while directing growing investment toward renewable energy, storage and nuclear power. Its plans also include gas, hydroelectricity, industrial power partnerships and a hydrogen hub producing fuels for potential overseas customers.

The spending commitment is substantial even before the full decade is complete. The Rs 7 lakh crore planned for the first five years represents about 41 per cent of the Rs 17 lakh crore total. The company has described the programme both as an investment over the next ten years and as an expansion extending through fiscal 2037.

Renewables Lead the Planned Capacity Increase

NTPC expects renewable energy to provide the largest part of its future capacity growth. It aims to increase renewable capacity from about 12 gigawatts operating now to 60 gigawatts by fiscal 2032 and 136 gigawatts by fiscal 2037.

The first target would multiply its current renewable capacity by five. The second would take it to more than eleven times today's level. Against the company's planned portfolio totals, renewables would represent 40 per cent of capacity in fiscal 2032 and about 54 per cent in fiscal 2037.

NTPC Group currently has a portfolio of approximately 127 gigawatts, comprising about 91 gigawatts in operation and 36 gigawatts under construction, according to figures presented at its annual analyst and investor meeting. Singh put the construction figure at 37 gigawatts in his summit remarks, including around 17 gigawatts of coal projects.

Those projects provide a substantial starting point for expansion, but the longer targets require much more construction. The planned 250 gigawatts in fiscal 2037 would be about 2.75 times the capacity operating today.

NTPC executives described coal, renewable energy supported by storage, and nuclear power as the "three legs" of India's energy security. Each has a different role: coal and nuclear plants can provide sustained generation, while solar and wind output varies with weather and time of day. Storage allows some electricity to be saved and delivered later.

Why Coal Is Still Expanding

Singh said India's electricity grid had around 557 gigawatts of capacity, with non-fossil sources accounting for about 55 per cent. Coal nevertheless supplied almost 70 per cent of electricity generated.

Capacity measures the maximum potential output of power plants. Generation measures the electricity they actually produce over time. A solar installation produces during daylight hours, while a coal station can operate at night, so the shares of installed capacity and electricity production can look very different.

NTPC's coal capacity could rise from about 67 gigawatts to around 91 gigawatts under current plans. That is an increase of 24 gigawatts, or roughly 36 per cent, even as renewable capacity grows much faster.

Singh said generation from coal plants had risen about 18 per cent in the month he was discussing, compared with an increase of approximately 10 per cent previously. He also pointed to difficulties keeping adequate coal stocks at power stations as generation requirements increased.

Singh identified weather patterns associated with El Niño, economic expansion and cooling demand as contributors to rising electricity use. El Niño is a climate pattern involving warmer surface waters in part of the Pacific Ocean that can influence weather elsewhere, including conditions affecting electricity demand.

Artificial intelligence and data centres add another source of demand. Computers processing and storing information need electricity, and the equipment used to keep them cool consumes more. NTPC's investment approach reflects the need to serve these growing loads while expanding sources with lower carbon emissions.

Storage Must Cover a Longer Demand Window

Singh said the period over which the power system needs to meet sustained demand had lengthened from around four hours toward ten to twelve hours. A longer demand window changes the job of storage: it must deliver electricity over more hours, rather than cover only a brief evening peak.

NTPC is pursuing pumped storage, vanadium flow batteries and carbon dioxide batteries as alternatives to conventional lithium batteries. Singh linked this diversification to reducing dependence on imported materials and building domestic technology capabilities.

Pumped storage uses electricity to move water to a higher reservoir. When electricity is needed, the water flows down through turbines. Vanadium flow batteries store energy in liquid solutions held in tanks, while carbon dioxide storage systems use compression and expansion processes to store energy and recover it later.

NTPC expects its first carbon dioxide battery installation to be commissioned in the first half of November. Singh said the technology could be replicated at other locations and used alongside large solar parks. Such storage could help move some daytime solar output into hours when sunlight is unavailable.

Singh also referred to government incentives for advanced battery cell chemistry. His wider argument was that India needs domestic capabilities and several storage options as electricity demand changes, rather than relying on a single technology.

Anil Razdan, a former power secretary and chairman of the Indian Chamber of Commerce Expert Committee on Energy, explained why storage matters for renewable generation:

Renewable energy offers enormous potential, but its intermittent nature makes storage an essential part of the power system. Unless adequate storage infrastructure is developed, we will not be able to realise the full potential of renewable energy.

Nuclear Plans Depend on Sites and Construction

NTPC aims to develop about 6 gigawatts of nuclear capacity by fiscal 2037, within its longer ambition of 30 gigawatts by 2047. The 2047 target would equal 30 per cent of India's national goal of 100 gigawatts.

Singh said NTPC had identified three proposed sites and submitted them for clearance to the Department of Atomic Energy and the Atomic Energy Commission. The locations and approval dates were not specified.

India's nuclear expansion is also opening to wider private participation. Atomic Energy Commission Chairman Ajit Kumar Mohanty, who is secretary of the Department of Atomic Energy, said private companies could invest around Rs 7.5 lakh crore and contribute 30 gigawatts by 2047. NTPC's ambition and the private sector contribution are separate components of the national expansion.

Mohanty said the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act, known as the SHANTI Act, was enacted in December 2025. It opened the sector to broader public and private participation while retaining sovereign control over sensitive activities.

Mohanty estimated the capital requirement at around Rs 25 crore per megawatt. Applied to 30 gigawatts, or 30,000 megawatts, that figure produces Rs 7.5 lakh crore, matching his estimate for private investment. Nuclear plants require large spending before they begin producing electricity.

Nuclear Power Corporation of India Limited operates 24 reactors with about 9 gigawatts of capacity. Another 17 reactors, totalling around 13 gigawatts, are under implementation. Mohanty said nuclear projects typically take five to seven years to build, depending on technology, approvals and construction requirements.

Mohanty also expected a couple of private companies to be operating reactors within five years. Companies are assessing technology, fuel supply, land and possible partnerships with Nuclear Power Corporation of India and foreign providers.

Smaller Reactors and India's Fuel Programme

India is exploring small modular reactors for specialised electricity needs, including industrial facilities requiring large and dependable supplies. Mohanty identified steel and cement as industries where such reactors could potentially provide captive power, meaning electricity generated primarily for the industrial consumer's own use.

Smaller reactors would add another option alongside large nuclear stations. Their use would depend on reactor design, regulatory requirements and the commercial arrangements between the generator and industrial customer.

India is also advancing its programme to make greater use of domestic nuclear resources. Its Prototype Fast Breeder Reactor at Kalpakkam in Tamil Nadu attained first criticality in April 2026. First criticality means the reactor began a sustained nuclear chain reaction, an important stage before full operation.

Mohanty described a programme with three stages. Uranium reactors generate electricity and produce plutonium that can be recovered from used fuel. Fast breeder reactors use that material in the second stage, supporting the eventual use of thorium in the third. Thorium must first be converted into suitable reactor fuel.

Mohanty said India holds about 25 per cent of global thorium reserves, including deposits associated with beach sand minerals in states such as Odisha and Andhra Pradesh. India has also signed agreements for peaceful civil nuclear cooperation with 18 countries, providing a basis for international partnerships as its reactor fleet expands.

Green Fuels Need Buyers Beyond Pilot Projects

NTPC is discussing green ammonia and other green fuels with potential buyers in Japan, South Korea and Germany. Its proposed hydrogen hub in Andhra Pradesh is intended to produce green ammonia and green methanol, while a pipeline stretching 20 kilometres is under construction at Simhadri to connect supply with overseas customers.

Green hydrogen is made by using electricity from renewable sources to split water into hydrogen and oxygen. It can then be used to make products such as ammonia and methanol. Those products offer additional ways to use and transport energy derived from renewable electricity.

Singh said NTPC's next step was to turn demonstrations into businesses supported by dependable demand:

We have to make hydrogen a business with the focus shifting from pilot projects to commercially viable ventures.

NTPC's discussions are with potential buyers; purchase agreements, export volumes and delivery schedules have not been announced. Securing customers matters because a production plant needs reliable revenue to support investment and operation.

India targets annual green hydrogen production of 5 million metric tonnes by 2030, backed by government support of about $2.1 billion. NTPC has already tested hydrogen in transport, with ten hydrogen buses operating. Singh said the first five were deployed in Leh-Ladakh around two and a half years earlier, using hydrogen produced with solar electricity.

Industrial Partnerships Could Use Heat More Efficiently

NTPC is examining a model under which it could take a 26 per cent equity stake in captive power arrangements with industrial consumers. Equity participation means owning a share of the project, rather than acting solely as an electricity supplier.

Singh said cogeneration could help reduce industrial power costs and carbon emissions. Cogeneration produces electricity and puts some of the heat from that process to use, for example in a factory. Conventional electricity production often releases much of that heat without using it.

Singh cited potential efficiency of around 70 per cent when useful heat and electricity are counted together. For an industrial consumer that needs both, recovering heat can allow more productive use of the same fuel.

The precise structure and scope of the proposed equity model require further clarification. NTPC's interest connects its expansion plans with industrial customers seeking dependable power and lower operating costs.

Finance and Forecasting Matter Alongside New Plants

Razdan said geopolitical tensions and disruptions to global energy transportation were reshaping markets and adding cost pressures. He called for stronger finances at power distribution companies, timely collection of revenue and a regulatory environment that supports investment.

Distribution companies deliver electricity to consumers and collect payment. Their ability to recover revenue affects the funds available to pay generators and sustain investment across the electricity system.

Ghanshyam Prasad, chairperson of the Central Electricity Authority, called for advance planning and stronger demand forecasting, including for data centres. Forecasting means estimating when and where electricity will be needed so generation, storage and delivery infrastructure can be prepared.

Prasad also supported domestic manufacturing of power sector components to reduce dependence on global supply chains. Singh made a similar point about NTPC's technology priorities:

Technology self-reliance will be equally important as energy security.

NTPC's programme therefore involves more than adding generating capacity. Storage duration, fuel availability, nuclear approvals, paying industrial customers and demand forecasts will all influence whether new assets can supply affordable electricity when it is needed.

The Milestones From 2025 to 2047

NTPC's plans stretch across several investment and construction periods. The nearer milestones involve storage and renewable capacity, while the largest nuclear ambitions extend to 2047.

• December 2025: The SHANTI Act opened nuclear energy to wider public and private participation.
• April 2026: The Prototype Fast Breeder Reactor at Kalpakkam attained first criticality.
• October 13, 2026: Singh outlined the investment programme and technology priorities at the India Energy Summit in New Delhi.
• First half of November 2026: NTPC expects to commission its first carbon dioxide battery installation.
• 2030: India targets annual green hydrogen production of 5 million metric tonnes.
