Coal India cites 168 MT buffer to ease summer fears

What Coal India said on summer coal availability

State-owned Coal India Limited (CIL) said it has built a coal buffer of 168 million tonnes (MT) to meet increased demand during the summer season. The company sought to allay concerns about coal shortages at thermal power plants, even as daily coal consumption by such plants has risen.

CIL said the available coal in the system is adequate to meet the generation capacity of domestic coal-based plants. It also argued that lower stock levels at coal-fired plants during peak summer periods are a normal pattern rather than a supply-side crisis.

The 168 MT buffer - where the coal is sitting

CIL’s statement broke the overall coal availability into stock held at power plants, inventory at mine heads, and coal positioned across transit routes and rail movement. The company said this combination adds up to 168 MT of coal available in the system.

Coal stocks at domestic coal-based power plants were reported at 47.6 MT as on May 23. Inventory at CIL’s mine heads was 113.5 MT as on May 24.

Beyond these, CIL said around 3 MT of coal was awaiting movement at transit points such as goods sheds, private washeries and ports. It added that “rakes on run”, or coal in transit at any point of time through rail networks, was around 4 MT.

Inventory at mine heads up 10% year-on-year

CIL said inventory at its mine heads stood at 113.5 MT as on May 24, which it described as a comfortable level. It also noted that mine-head inventory was up about 10% from the year-ago period.

The company linked this inventory position to its ability to supply domestic coal-based generation units during a period when power demand typically rises. CIL’s communication was aimed at countering market concerns that the system could see disruptions if stock at plants drops in peak summer.

Stock cover: “sufficient to meet 19 days of consumption”

CIL stated that the current stock level is sufficient to meet around 19 days of consumption. The company did not provide a daily burn rate figure in the statement, but framed the 19-day cover as evidence of adequacy.

It also said that compression of coal stock levels at coal-fired power plants during peak summer is a “natural occurrence.” In CIL’s framing, stock drawdowns at plants reflect demand dynamics and logistics cycles rather than a breakdown in supply.

Additional fallback: 50 MT of in-situ mine coal

Along with the stated coal buffer, CIL said there is around 50 MT of in-situ mine coal on tap. The company described this as coal that is ready for quicker extraction and supply if demand necessitates.

This in-situ availability was presented as an additional layer of readiness, in case coal burn at thermal power plants stays elevated for longer or if replenishment needs accelerate.

Plants under “criticality” and the sourcing mix

CIL referred to 21 power plants categorised under criticality as of May 20. Of these, 11 were domestic coal-based plants.

Among those 11 domestic coal-based plants, CIL said seven source their coal from CIL. The company did not name the individual plants in the statement, but the disclosure highlights that CIL’s supply position can materially influence the stock situation at several plants considered sensitive from a fuel-availability standpoint.

CIL’s coordination with power plants on stock-building

CIL said it has been corresponding with power plants to build up their stocks for peak demand periods in advance, when there is ample coal. It also highlighted the case of plants located at difficult logistic points.

The emphasis on advance stock-building is notable because plant-level inventory can fall for reasons unrelated to production, including rail movement timing and the physical distance from coal sources.

Background: Earlier buffer and in-transit numbers cited by CIL

In an earlier update dated Feb 27, CIL had said it was geared up to meet a potential surge in summer coal demand as power consumption begins to rise. In that disclosure, CIL said coal stocks at domestic coal-based thermal power plants stood at nearly 55 MT as of Feb 25, which it described as the highest level for that period.

It also said 5.5 MT of coal was available in transit at goods sheds, washeries and ports at that time. CIL stated that cumulative on-tap availability across these sources stood at around 175.5 MT, and that in-situ coal exposure at mines accounting for 90% of CIL’s annual output was 60.2 MT as of mid-February.

Market impact: What this means for summer power supply concerns

CIL’s latest numbers are aimed at addressing a recurring seasonal issue: when summer power demand rises, coal-fired plants often draw down inventories faster than they can rebuild them. By highlighting 168 MT spread across power plants, mine heads, transit points and rakes on run, CIL is signalling that the supply chain has coal positioned at multiple stages.

The company’s assertion that stock compression is “natural” is also intended to reduce the risk of interpreting plant-level inventory declines as a broader shortage. For investors and market participants tracking power supply stability, the key datapoints in the statement are the 19 days of consumption cover and the mine-head inventory that is up about 10% year-on-year.

Why the update matters

Concerns around coal availability can have knock-on effects across power generation, grid stability, and industrial activity during peak months. CIL’s disclosures give a quantified view of coal on hand and coal in motion, and also point to coordination efforts with plants, particularly those at difficult logistic points.

The reference to plants under criticality and the fact that seven of the 11 domestic coal-based plants in that category source coal from CIL adds context on where coal supply pressures are closely watched.

Conclusion

CIL said 168 MT of coal is currently available across plants, mine heads and transit routes, and that the stock is sufficient for around 19 days of consumption. The company also pointed to 50 MT of in-situ mine coal ready for quicker extraction if demand requires, while reiterating that summer stock compression at plants is not necessarily a supply-side crisis.
