India's 97 GW Coal Expansion Plan Looks Too Small, Senior Official Says

India planned to add 97 gigawatts of coal-fired capacity by 2035. That plan could now rise to 105 GW or even 150 GW. The change reflects a sharp increase in electricity demand over the past year, according to Ghanshyam Prasad, chair of the Central Electricity Authority.

The key issue is dependable supply. Coal plants can provide power when demand is high and help support the grid continuously. Prasad said growing demand requires stable supply resources, not only more total generating capacity.

India already had 231 GW of coal and lignite capacity in August. Yet renewable capacity also reached 243 GW, showing that both sources are expanding. If demand continues rising, India may revise its 2035 coal target upward. The article also identifies nuclear power as another future option, with India targeting 100 GW by 2047.

India’s coal and lignite fleet stood at 231 gigawatts in August. That represented 42% of the country’s total power capacity, according to the Centre for Research on Energy and Clean Air. Coal remains a major part of India’s electricity system.

Renewable capacity excluding large hydro reached 243 GW in the same month. It represented 44% of total capacity, slightly exceeding coal and lignite. Renewables had grown from 193 GW, or 39%, in August 2025. This was the fastest growth among the major capacity categories.

The comparison measures installed power capacity, not electricity produced. A larger renewable capacity total does not automatically mean renewables supply more electricity at every moment. India still expects to add coal capacity because demand is rising and officials emphasize the importance of stable, flexible supply for grid operation.

Electricity demand and supply must stay balanced across the grid. When demand rises quickly, generators and networks must respond without leaving customers short of power. This makes dependable resources and flexible operations more important.

For example, a coal plant can provide steady output for long periods. Other resources, such as storage or responsive generation, can adjust when demand changes. The article does not quantify these balancing needs, but Ghanshyam Prasad said India needs stable supply resources as demand grows. That is the central mechanism behind the proposed coal expansion.

India’s demand surge has already made its earlier 97 GW coal-addition plan look potentially too small. The target could rise to 105 GW or 150 GW by 2035. At the same time, renewable capacity is expanding quickly, so India’s challenge is combining growth with reliability rather than choosing capacity based on one source alone.

Coal-fired power capacity means the maximum electrical power that a group of coal plants is designed to produce at a moment, usually measured in gigawatts. It describes the size of the generating fleet, not its total yearly output. India’s reported 231 GW is therefore a capacity figure.

Installed capacity is the equipment available to generate electricity. Actual generation depends on how often plants run, their operating limits, maintenance, fuel availability, and demand. A plant with 1 GW of capacity can produce 1 GW at full output, but it may operate below that level or stop at other times.

This distinction matters when comparing coal with renewables. India had 243 GW of renewable capacity excluding large hydro, but that figure does not show how much electricity renewables generated. Comparing generation requires energy units, such as gigawatt-hours, and a defined period.

Installed capacity is not the same as dependable electricity at every moment. Solar and wind capacity can be large, yet their output changes with sunlight and wind conditions. A country can therefore have more renewable capacity on paper while still needing resources that support the grid during shortfalls.

India illustrates this tension. Renewables excluding large hydro reached 243 GW in August, compared with 231 GW of coal and lignite. Even so, the Central Electricity Authority said demand growth requires stable supply resources. Coal plants can provide sustained output when operating, helping cover demand while renewable production varies.

This does not mean renewables are unimportant. Renewable capacity grew from 193 GW in August 2025 to 243 GW in August 2026, the fastest increase described in the article. India’s planning challenge is to integrate that growth while maintaining reliable supply. The article also points to nuclear power as another firm-capacity option.

India has several possible ways to meet demand while limiting additional coal. Nuclear plants can provide large, steady output. Energy storage can shift electricity from periods of surplus to periods of high demand. Stronger transmission networks can move power between regions and connect renewable projects with consumers.

The article gives one concrete alternative: India aims to raise nuclear capacity from 8.8 GW to 100 GW by 2047. It has also allowed private investment in nuclear energy and expects to build five small modular reactors domestically by 2033. Storage and transmission are not quantified in the source, but they can improve flexibility.

These options could complement, rather than automatically replace, coal. India’s renewable capacity reached 243 GW in August, while demand is rising quickly. A broader mix of nuclear, renewables, storage, and transmission could reduce reliability risks. The article does not state whether these measures would eliminate the proposed coal additions.

One gigawatt is a unit of power equal to one billion watts. It describes an instantaneous rate or a plant’s maximum output. When India reports 231 GW of coal capacity or 243 GW of renewable capacity, it is describing the potential size of those fleets.

Energy generation is different. It measures how much electricity is actually delivered over a period, commonly in gigawatt-hours. A 1 GW plant operating continuously would produce more energy than a 1 GW plant operating only part of the time. Operating patterns vary among coal, nuclear, wind, and solar facilities.

That distinction prevents misleading comparisons. India’s renewable capacity slightly exceeded coal capacity in August, but the article does not provide generation totals for either source. Capacity shows available scale; generation shows actual contribution. Reliability also depends on when electricity is available, not only on the number of gigawatts installed.
