Burning Less, Building More (The Quiet Demotion of Indian Coal)
SYNOPSIS
India's coal-fired power generation fell in FY26, only the third decline in five decades. Cheaper clean power, water stress and Europe's carbon tax are squeezing coal as a fuel. Yet demand for coal as a raw material for steel keeps rising. Coal is changing jobs.
India's coal-fired power generation fell in FY26, only the third decline in five decades. Cheaper clean power, water stress and Europe's carbon tax are squeezing coal as a fuel. Yet demand for coal as a raw material for steel keeps rising. Coal is changing jobs.
For fifty years, coal has kept India's lights on. Roughly 7 out of every 10 units of electricity in the country still come from burning it. But in FY26, something cracked. Coal-fired generation fell from 1,331.8 billion units to 1,280.5 billion units, a drop of almost 4%. According to the International Energy Agency, 2025 was only the third year in five decades that India's coal power declined.
Why? Start with price. In a recent 1,000 MW round-the-clock auction by the Solar Energy Corporation of India (SECI), renewable power backed by storage was won at ₹5.25 a unit, fixed for 25 years. Seven coal power deals signed in 2025 started at ₹5.38 to ₹6.30 a unit. And the clean tariff stays flat for a quarter of a century, while coal tariffs typically move with fuel costs and inflation.
Then there is water. A coal plant boils water to spin its turbines and needs even more to cool them down. Almost 90% of India's thermal power depends on freshwater for this. In 2026, El Niño gave India its fifth-driest June since 1901, and by September around 161 reservoirs were over 32 billion cubic meters short of last year.
Water is a problem India faces at home. The next one comes from abroad.
The European Union now charges a carbon border tax, called CBAM. It does not tax the coal India burns for its own electricity. It taxes the coal used to make the steel India sells to Europe. Most Indian steel is made in blast furnaces that run on coal, so it carries a heavy carbon bill. On default emission values, Indian blast-furnace steel faces a CBAM cost of about €254 a tonne, according to Argus and Fastmarkets estimates. Steel from Turkey, made mostly by melting scrap in electric furnaces, faces about €100.
But here is the twist. In the same year that power plants cut thermal coal imports by 27.5%, India's imports of coking coal rose 15.2% to 66.33 million tonnes, a five-year high.
The difference between the two matters. Thermal coal is burned for heat to make electricity, and it has cheaper rivals. Coking coal is a special grade that is baked in ovens to make coke, a hard, carbon-rich fuel that blast furnaces need to turn iron ore into iron. There is no easy substitute for it, and India is targeting 300 million tonnes of steel capacity by 2030.
Coking also produces a sticky by-product called coal tar. Refined further, it can become needle coke, the material used to make graphite electrodes for electric steel furnaces and graphite for battery anodes. Separately, the government has cleared a ₹37,500 crore scheme to turn coal into gas for fertilizers and chemicals instead of burning it.
None of this means coal is finished. When the drought cut hydropower by nearly 21% in June, according to power ministry data reported by Bloomberg, it was coal that kept the grid running. And for mining towns like Dhanbad and Korba, even a slow decline means fewer jobs.
For investors, the coal story is splitting in two. Coal as a fuel is losing its edge. Coal as an ingredient is gaining one.
So the real question is not whether India still needs coal. It is which kind of coal still has a future.
