Forty-five Indian thermal power plants are down to critically low coal, up from 31 a month ago, as a 12% monsoon deficit and El Nino heat keep air-conditioning demand running through the night
28 Aug, 04:27 IST · Plays out within days · 1 source
Forty-five coal power stations have less than three days of fuel left because it is unusually hot and the rains failed, so electricity gets pricier for everyone and Coal India is asked to dig faster.
Key facts
What the reporting establishes, before any reading of it.
- 45 coal-fired plants held under 25% of normative stock or under three days of fuel as of 25 August, up from 31 at end-July
- India's monsoon rainfall is 12% below normal, so hydro is weak and night-time cooling demand stays high
- The power ministry told some plants to defer planned maintenance and set up a Core Management Team with the CEA and Coal India for daily monitoring
- An NTPC official described coal supply as hand-to-mouth
How the news spreads
Step by step — from the first companies it hits to whole sectors.
Who it hits first
- Forty-five coal-fired power stations are running on under three days of fuel and are being told to ration generation and defer maintenance
- Generators that buy imported or e-auction coal - RattanIndia Power most of all, where coal is 68.4% of costs - face a direct cost squeeze they cannot fully recover
- State distribution companies face costlier power purchases just as air-conditioning demand peaks
Who may gain
- Coal India, which sells more tonnes through premium-priced e-auctions
- Generators with merchant capacity, which earn more per unit when scarce power lifts exchange tariffs
- Power-equipment and spares suppliers, as utilities buy emergency balance-of-plant items rather than take units offline
Along the supply chain
Downstream
State distribution companies buy costlier exchange power and either absorb the loss or seek tariff revisions; energy-intensive downstream users - cement, aluminium, steel and paper - face higher grid and captive power costs, and industrial consumers in states with the worst stock positions face load management.
Upstream
Coal India and its subsidiaries see dispatch pressure and daily government monitoring, while railway rakes and port handling for imported coal become the binding constraint; Indonesian and South African coal suppliers gain Indian orders as plants substitute imports for scarce domestic linkage coal.
Where demand moves
Business
Electricity demand is rising while coal deliveries fall short, so generation shifts from fuel-starved private plants to those with secure linkage supply, and the shortfall is bought on the power exchange at higher prices. Coal India captures the extra tonnage through e-auctions, and cement and steel makers that burn coal for captive power compete for the same scarce fuel.
Capital
Money rotates out of imported-coal and thinly capitalised generators such as RattanIndia Power and towards fuel-secure regulated names like NTPC and towards Coal India as the supplier. Because this is a cost and availability story rather than a demand story, investors favour companies that can pass fuel cost to customers over those that sell power at a fixed price.
How it spreads across sectors
Cement
Captive power and pet-coke costs climb into a weak-pricing season
Metals & Mining
Coal India dispatch and e-auction realisations rise; aluminium and steel smelters face higher captive power cost
Oil, Gas & Consumable Fuels
Imported coal and substitute fuel demand rises
Power
Fuel cost rises and generation availability falls; merchant-exposed generators gain on tariffs while fixed-price sellers lose

Note
This is an availability and volume shock, not a price shock - the tracked coal series is flat at 0% over one and three months and its price feed has been stale since 2025-12-26, so the modelled margin impact is 0 basis points and the damage shows up as lost generation rather than a higher per-tonne cost.

When it plays out
Immediate
Plants ration generation and defer maintenance; exchange power prices spike; the Core Management Team publishes daily stock positions
Medium term
If rains normalise, hydro returns and demand cools, stocks rebuild by the second half of the year; if not, the shortage feeds into tariff petitions and a second round of cost pressure across manufacturing
Short term
Imported coal orders and railway rake allocation decide who recovers first; state distribution companies start absorbing higher purchase cost
