Forty-Five Indian Power Plants Hit Critical Coal Thresholds as Monsoon Disrupts Supply
Plant stockpiles fell 15.5% in three weeks as El Niño amplifies demand, straining the domestic coal substitution drive that slashed imports to a four-year low.
Forty-five coal-fired power plants in India were operating below safe inventory thresholds as of Thursday (2026-08-27), with stocks at many sites insufficient for three consecutive days of generation or below 25% of required capacity, Reuters reported citing data from India's Central Electricity Authority.5
Inventories across India's power plants fell 15.5% between August 1 (2026-08-01) and August 23 (2026-08-23), as monsoon rains cut road and rail deliveries while a strong El Niño kept electricity demand elevated. The combination pushed stockpiles from manageable to critical at a speed that grid operators described as unusual for the August period.5
The stress lands at an exposed moment for India's coal supply chain. In the months before August (2026-08), the country had been aggressively substituting domestic coal for imported supplies at plants originally designed to run on seaborne fuel. By late June (2026-06-24), domestic coal accounted for 50% of the fuel mix at many of those import-designated facilities, with some plants reaching 70%, industry and government officials told Reuters at the time.3
India had shifted domestic coal to cover 5.7 gigawatts of the 18.7 gigawatts of capacity at import-reliant plants, with efforts to move another 4.3 gigawatts underway, Reuters reported. Thermal coal imports slumped to a four-year low between January and May (2026-01-01 to 2026-05-31), down 12% from a year earlier, according to commodities consultancy BigMint.3
That import-reduction approach saved money when global prices were firm. But plants running on domestic coal draw from inland supply chains — road and rail networks that monsoon rains disrupt more severely than the coastal logistics that imported coal depends on. The 15.5% inventory decline between August 1 (2026-08-01) and August 23 (2026-08-23) reflects that vulnerability directly.5,3
Coal India had moved earlier in the year to address tightness. In late May (2026-05-25), the state-owned miner asked its subsidiaries to accelerate deliveries to power plants as record demand during an intense heatwave forced rolling blackouts across several regions, two sources with direct knowledge of the matter told Reuters.2
Coal India chairman B. Sairam told Mint on August 25 (2026-08-25) that coal will remain at the center of India's energy mix until 2047, driven by industrialization, urbanization, and sustained demand growth. His statement frames the current inventory shortfall not as a transition artifact but as a recurring supply management problem in a sector with a long operational runway.4
That view sits against a notable 2025 data point. Carbon Brief analysis published in May (2026-05-19) showed coal power generation in India fell 3.0% year-on-year — a reduction of 46 terawatt hours — the first simultaneous drop in both India and China in 50 years. China's decline was 1.6%, or 90 terawatt hours, even as total electricity demand there grew at 5% annually. Record clean-energy additions in both countries drove both declines.1
The August (2026-08) crisis underscores the gap between generation trends and supply-chain readiness. Coal still accounts for around 60% of India's total power output, and the plants facing stock shortfalls are not marginal operators — they are core baseload capacity running against hard physical limits.3
Newcastle coal physical was trading at $135.69 per tonne on September 4 (2026-09-04). JKM, the Asian LNG benchmark, was at $23.76 per MMBtu on September 4 (2026-09-04). Neither price has shown a sharp response to the Indian inventory data, suggesting markets expect the monsoon-driven supply disruption to ease as the season winds down. How quickly Coal India can rebuild buffers at the 45 affected plants — and whether El Niño keeps demand elevated long enough to prevent restocking — is what coal market participants are now watching.5,3
