India’s Coal Stocks Slide as Power Demand Surges
India’s power plants are using coal faster than they can replace it.
This is happening because people and businesses are using unusually large amounts of electricity.
Hydropower is also producing less electricity because rainfall has been below normal in some areas.
As a result, coal plants are working harder to keep the electricity supply steady.
By September 27, their coal stocks were much lower than the amount considered safe.
Many plants had less than one-quarter of their recommended supply.
The government ordered many captive power plants to run at full capacity to add more electricity to the system.
Improved rainfall could reduce demand, but very heavy rain could also make coal mining and transport more difficult.
Coal stocks at India’s domestic coal-fired power plants fell nearly 24%, from 25.4 million tonnes on September 1 to 19.2 million tonnes on September 27.
Stocks were 64% below the required level, while at least 72 of 168 plants held critically low inventories.
Peak electricity demand reached a September record of 269 gigawatts on September 10, just below the annual peak of 270 GW.
Coal-based generation rose 15.5% during September 1-26, while hydropower generation declined 15.5% from the same period last year.
The government invoked Section 11 of the Electricity Act, directing about 112 captive coal plants to operate at maximum capacity from October 1 through December 31.
- Who
- India’s domestic coal-based power plants, the Indian government, and captive coal-fired power plants are involved.
- What
- Coal inventories declined sharply as electricity demand and coal-based generation increased while hydropower output fell.
- Where
- Across India’s domestic coal-based power plants and captive coal-fired power plants.
- When
- Stocks were assessed on September 27; the government’s order applies from October 1 through December 31.
- Why
- High electricity demand, lower hydropower generation, and monsoon-related disruptions to coal mining and evacuation increased pressure on coal supplies.

“While overall mining output was lower, the coal supply to the power sector witnessed some increase. Lower coal availability owing to monsoons and elevated Plant Load Factor (PLF) for thermal power stations led to pressure on coal inventory levels at several power plants, with inventory falling critically below the normative levels,”

“There are signs of a tighter supply environment that warrant proactive management of available thermal capacity. Peak demand has remained elevated, reaching around 270 GW, while coal stocks at a number of thermal plants have come under pressure.”
