🗞️ Why in News Coal India Limited (CIL) said on 5 October 2026 that its coal supplies to the power sector rose to 48.90 million tonnes (MT) in September 2026, up 10.63% on a year earlier, and its offtake in the first half of 2026-27 rose 7.6%. Yet the latest Central Electricity Authority (CEA) data, analysed by The Hindu on 6 October, show 84 of 191 thermal power plants with critically low coal stocks, as power demand runs at record levels.
Two Sets of Numbers
| What CIL reports (H1 = April to September 2026) | Figure | A year earlier |
|---|---|---|
| Total offtake, H1 FY 2026-27 | 384.2 MT (+7.6%) | 357.0 MT |
| Offtake, Q2 (July to September) | 186.04 MT (+12.05%) | 166.04 MT |
| Supply to power sector, H1 | 302.8 MT (+6.1%), about 79% of offtake | 285.4 MT |
| Supply to power sector, September | 48.90 MT (+10.63%), about 1.63 MT a day | 44.20 MT |
| Pithead stock drawn down in H1 | 63 MT | |
| Domestic coal-based generation, H1 | 640.05 billion units (+9.9%) | 582.5 BU |
| What the plant data show (The Hindu, from CEA) | Figure |
|---|---|
| Thermal plants tracked | 191 |
| Plants with critical stocks, as of 30 September | 84 (more than 44%) |
| CEA’s test for “critical” | Stock below 25% of the normative stock, or enough for less than three days of generation |
The Coal Ministry’s position, as Union Coal and Mines Minister G. Kishan Reddy put it on 28 September, is that there is no coal shortage, only a surge in demand.
Why Both Can Be True
1. Demand has outrun supply growth. The Hindu reports that power demand grew about 10% in 2026, the steepest annual rise in a decade. Supply up 6 to 11% does not rebuild stocks if burn rises as fast.
2. Stocks moved from the mine to the furnace. CIL drew down 63 MT of coal stored at its pitheads. That kept plants running, but it means the buffer at the mine is thinner, while plants burn coal as soon as it arrives.
3. Hydro fell short. A weak monsoon cuts hydroelectric output and raises demand for irrigation pumping, so coal plants carry more of the load. The Hindu links this to El Niño, with June 2026 recording India’s largest June rainfall deficit since 2014.
4. Heat drives cooling. The IMD recorded India’s hottest August since 1901, with a national mean of 28.01°C against a normal of 27.34°C. Fans and air conditioners add to demand, and the all-time peak demand of 270.8 GW was set on 21 May 2026.
5. Logistics, not only output. Coal must travel by rail from the coalfields of Jharkhand, Odisha and Chhattisgarh to plants across the country. Rake availability and evacuation capacity decide how much reaches a plant. CIL says 46 coal-handling plant silos give it 432 MT of mechanised loading capacity, with more planned.
Why It Matters
| Risk | Consequence |
|---|---|
| Outages | Plants with only days of coal must cut output when demand peaks, causing load-shedding |
| Costly substitutes | Distribution companies buy expensive power on exchanges or run imported-coal plants |
| Industrial supply | When coal is diverted to power, captive users such as aluminium, cement and steel can face shortfalls |
| Climate trade-off | Each shortage strengthens the case for more coal capacity, even as India targets 500 GW of non-fossil capacity by 2030 |
The Policy Toolkit
- Stocking norms. The CEA sets the normative stock each plant should hold, depending on its distance from the mine; the “critical” label is a warning, not a penalty.
- Imported-coal plants. The Centre has in recent years used Section 11 of the Electricity Act, 2003 to direct plants built for imported coal to run during shortages.
- First-mile connectivity. Mechanised loading at mines reduces delays and road transport of coal.
- Storage and renewables. Battery storage and pumped storage can shift solar power into the evening peak, reducing the pressure on coal plants at the hours when demand is highest.
- Demand management. Time-of-day tariffs and efficient cooling standards slow the growth of peak demand.
UPSC Relevance
GS Paper 3. Infrastructure: energy; mobilisation of resources; conservation and climate change. Prelims. Institutions (CEA, CIL), energy data and terms.
A question worth preparing. “India’s coal problem is less one of production than of logistics and demand planning.” Examine in the light of recent stock shortages at thermal power plants. (150 words)
The Mains framing. Present both datasets (CIL supply up; 84 of 191 plants critical), explain the gap (record demand, pithead drawdown, weak hydro, heat, rail logistics), and argue for a mix: higher stocking before peak seasons, rail and first-mile capacity, storage-backed renewables for the evening peak, and demand-side measures.
📌 Facts Corner, Knowledgepedia
Prelims, statement-ready facts:
- CIL power-sector supply, H1 2026-27: 302.8 MT, up 6.1%; about 79% of CIL’s offtake goes to power.
- CIL total offtake, H1 2026-27: 384.2 MT, up 7.6%.
- CEA: a plant is critical when stocks fall below 25% of the normative stock.
- 84 of 191 thermal plants were in the critical category as of 30 September 2026 (CEA data).
- All-time peak power demand: 270.8 GW, 21 May 2026.
- IMD: August 2026 was India’s hottest August since 1901 (mean 28.01°C).
Prelims, the traps:
- The CEA is a statutory body under the Electricity Act, 2003; it advises and sets technical norms but does not mine or sell coal.
- CIL is a Maharatna public sector company under the Ministry of Coal, not the Ministry of Power.
- “Offtake” is coal despatched from the mines; it is not the same as coal produced.
Mains, arguments and keywords:
- Energy security; peak demand; pithead stock; rake availability; first-mile connectivity; El Niño and hydropower; storage-backed renewables.
Interview, be ready for:
- “If coal plants are short of coal, should India build more of them?” India needs reliable power first, but the cheaper path to evening-peak reliability is storage, grid flexibility and efficiency, with coal used as a declining backstop.
