Coal stocks at thermal plants hold above 18 MT as supply deficit narrows

Coal stocks are the quantity of coal physically available at a thermal power plant for future generation. The stock is measured in tonnes and represents fuel already delivered but not yet burned. It matters because plants need supplies available every day to keep producing electricity.

A plant consumes coal continuously while trains or other supply routes bring in replacement coal. If incoming supplies match consumption, stocks remain stable. If consumption is higher, stocks decline. The article describes this difference as the rate of stock depletion.

On October 10, domestic thermal plants held 18.205 million tonnes. Stocks had stayed above 18 million tonnes since September 29, while daily consumption remained below 3 million tonnes. The government therefore said supplies were adequate. It also monitored plants with critical stocks and redirected coal to vulnerable stations when needed.

The available coal stock was 18.205 million tonnes on October 10. This is a large reserve compared with the reported daily consumption rate, which remained below 3 million tonnes. The comparison helps show how much fuel plants had available relative to their immediate needs.

Using the stated upper limit of 3 million tonnes per day, 18.205 million tonnes would cover more than six days of consumption. The exact number of days could be higher because the article says consumption was less than 3 million tonnes, not exactly 3 million tonnes.

The government described the stocks as adequate and said they had remained above 18 million tonnes since September 29. Thermal plants continued consuming coal while incoming supplies kept pace closely enough to prevent a sharp fall in the reserve.

Stock depletion measures how much faster plants consume coal than they receive it. A smaller depletion rate means incoming supplies are coming closer to matching daily use. This matters because slower depletion helps preserve the reserve and reduces pressure on power stations.

In September, the gap averaged 0.24 million tonnes per day. During the first 10 days of October, it narrowed to 0.06 million tonnes per day. The ministry linked the stabilisation to coal supplies keeping pace with plant consumption. It also closely monitored plants holding critical stocks.

Rail freight movement improved at the same time. Daily coal rake loading rose 10% to 469 in early October, compared with September’s daily average. The government also used requirement-based redistribution to send coal to vulnerable stations, helping reduce uneven shortages and support uninterrupted generation.

Rail shipments are a key link between coal supplies and thermal power plants. When more coal reaches plants each day, they can replace more of the fuel they burn. That reduces the gap between consumption and incoming supplies, helping reserves remain stable.

The average number of daily coal rakes rose 10% to 469 during the first 10 days of October, compared with the daily average for September. October’s daily loading ranged from 447 to 482 rakes. These figures show a sustained increase rather than a single delivery surge.

The stronger rail movement accompanied a sharp reduction in stock depletion. The gap fell from 0.24 million tonnes per day in September to 0.06 million tonnes per day in early October. As deliveries improved, plants could keep generating while drawing down their stored coal more slowly.

Coal availability matters especially when thermal power carries most of the electricity system during peak demand. The article reports that thermal power accounted for more than 60% of electricity generated at those times. Plants therefore need dependable fuel to keep meeting the highest demand periods.

If coal deliveries fall behind consumption, stocks decline and plants with critical reserves face greater pressure. The ministry said it was monitoring such plants closely and redistributing coal according to requirements. This approach aims to protect vulnerable stations and maintain generation.

The current position was described as stable. Plants held 18.205 million tonnes on October 10, and stocks had stayed above 18 million tonnes since September 29. Consumption remained below 3 million tonnes daily, while improved supplies and rail movement helped support uninterrupted power generation.

Requirement-based redistribution means directing available coal toward plants facing the greatest supply risk. It matters because coal stocks are not necessarily equal across all stations. Supporting a vulnerable plant can help prevent a local shortage from interrupting generation.

The ministry said supplies to plants with critical stocks were being closely monitored. Coal was then redistributed according to requirements to vulnerable stations. The article presents this as a coordinated response alongside regular supply flows, rather than as a replacement for normal deliveries.

This process helped support adequate supplies and uninterrupted power generation while overall stocks remained stable. On October 10, domestic thermal plants held 18.205 million tonnes. The government also reported that incoming supplies were keeping pace more closely with daily consumption, reducing the average depletion rate to 0.06 million tonnes per day in early October.

The article focuses on coal availability, not the generation process. Generally, a coal-fired thermal plant converts coal’s chemical energy into electricity by burning the coal and using its heat to make steam. This is why a steady coal supply matters for continued generation.

Coal is burned in a boiler, where its heat turns water into high-pressure steam. The steam flows across turbine blades and makes the turbine spin. The turbine is connected to a generator, so its rotation drives the generator to produce electrical power. The electricity is then sent onward through the power system.

After passing through the turbine, the steam is cooled back into water and can be used again. This process continues as long as the plant has coal, water, and operating equipment available. In the article’s context, stored coal and incoming rail supplies help maintain this continuous operation.
