A rough ride for coal to power sector as Indian Railways struggles with capacity

As on May 1, some 83 of the 150 power plants running on domestic coal reported critically low coal levels and many of them cited lack of rakes as the reason. On April 29, the railways cancelled 657 mail and passenger trains to ensure faster movement of coal rakes

Nearly 70 percent of India’s electricity comes from coal, and most of that coal is delivered to power plants by railroads.

If the power sector injects life into the economy, the Indian Railways (IR) is the lifeline that breathes life into the power sector.

As on May 1, some 83 of the 150 power plants running on domestic coal had critically low fuel stocks and many of them cited lack of rakes as the key reason. Eleven imported coal-based power plants also had an alarmingly low level of the fuel.

Since 2006, there have been 10 instances when more than 50 thermal power plants in India reported critically low coal levels, the last of which was in October 2021.

While the state-run, near-monopoly Coal India has struggled to scale up its production, the constraints in the rail transport infrastructure has only made the situation worse.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

The lifeline

In 2021-22, the Indian Railway transported 653 million tonnes (MT) of coal, around 111 million, or 20.4 percent, higher, compared to 2020-21. Around 46 percent of the IR’s total freight cargo comprised coal in 2021-22.

Out of the 653 MT coal transported by the railways, around 83 percent, or around 540.4 MT, was to thermal power plants. The remaining was to foundries of different manufacturing units.

According to railway ministry data, nearly 95 percent of coal transported by the IR comes from Coal India’s reserves while the remaining is imported coal.

Rail transport is economical, compared to other modes of transport. Also, road transportation and inland shipping have physical limitations, which make railways the preferred choice.

“Lack of proper roads connecting coal mines and quarries across India, the high fuel cost of trucks, slower movement through trucks and higher pollution by trucks make it infeasible for coal to be transported in trucks in India,” an official from a large domestic logistics company said.

Coal is gold for IR

The power sector depends on IR, and coal transport makes up nearly 47 percent of IR’s freight revenues and has an even higher share in its profits.

“IR’s business model is based on passengers underpaying and freight overpaying. Therefore, coal, its largest transported commodity, play a very big role in its revenues,” a logistics expert from Goldman Sachs said.

Puneet Kamboj, Research Assistant, Brookings India, said: “Since 2012, IR’s coal freight charges have grown more than 3-4 times the wholesale inflation rate.”

As per their research, the IR today explicitly overprices coal freight by about 31 percent to offset coaching losses for its passenger operations, he said.

In 2020-21, this “overcharge” from coal to thermal power plants stood around Rs 148 billion, thus increasing the cost of power, on an average, by about 10 paise per unit, on the basis of the electricity generated in the country.

“For coal carried by railways, on an average, this number is Rs 0.41/kWh in FY2021. For power plants in distant states, which inherently rely on railways for coal, this number can be three times higher,” Kamboj said.

The railway data shows that in the last five years coal revenue has grown at a faster rate than that from other commodities.

But even as coal continues to be a major source of revenue for the railways, the capacity for coal transport has not increased significantly.

Need for speed

“Before 2016, the biggest reason for coal shortage was the shortfall in Coal India’s output. However, in the last three years, production by Coal India has picked up. However, a combination of logistical bottleneck and payment issues still cause a coal shortage,” said a senior infrastructure expert.

In fact, so serious is the coal supply-logistics issue that the IR has cancelled many mail and express trains to facilitate faster movement of coal rakes, he said.

On April 29, IR said 657 mail and passenger trains will be cancelled till May 24 to deal with an unprecedented shortage of the vital input at thermal power plants. While the IR plans to restore operations when possible, at least 21 mail and express passenger trains may remain cancelled till May 24.

The IR supplies coal directly to around 130 of the 150 thermal power plants running on domestic coal, while the remaining plants are supplied indirectly.

“Around 20 thermal power plants are not directly connected with high-speed railway lines, or have not maintained their tracks properly, due to which there is no last-mile connectivity to these plants,” a senior government official said.

On an average, IR transports coal to thermal power plants on a biweekly basis, on a rotating quota to different power plants, through goods trains that are run on mid to high priority, depending on the requirement by the power plant.

Till September 2021, the IR used to transport coal using around 300 rakes per day. In April, it was increased to 410 per day.

Imported coal-based power plants run by Tata Power, Adani Power, Essar Power, ILF&S Tamil Nadu, Coastal Energen, Udupi Power and GSECL Sika Ltd, all have dedicated rail tracks with their own carriages to transport coal.

While most power plants run on imported coal operate dedicated railway lines from ports, IR does transport imported coal to power plants, if needed.

The capacity challenge

While the Indian Railway has said that it has allocated the highest possible capacity for coal transportation, demand has historically increased faster than the infrastructure needed to produce and transport coal in the country.

“For the last three years, power consumption has been stagnant. So, it didn’t matter that Coal India’s production did not see a rise. In FY22, coal consumption grew by 8 percent, but Coal India’s production did not grow significantly. Then there was the problem of a severe shortage of rakes.

Almost 60 MT of coal is lying with Coal India but cannot be transported,” Debasish Mishra, partner & leader (energy), Deloitte India, told Moneycontrol, on April 19.

A senior official from the Indian wagon industry said: “Before 2016, the IR was eyeing an incremental growth of, say 3-5 percent every year, and was carrying around 700-800 MT of traffic annually.”

IR would now order for 8,000-10,000 wagons every year to meet the targeted incremental growth, he said.

In the last five years, though IR’s freight loading has doubled, its orders for wagons have not increased accordingly.

The IR cannot increase capacity allocation to transport coal in India without disrupting the supply chain in other sectors.

Nearly 50 percent of all rakes available are used for coal supply. If the rake allotment is increased by 5-10 percent, there will be a shortage of cement and steel.

The bottlenecks

Many thermal power plants are not connected with high-speed railway lines, or have not maintained their tracks properly. This has led to delays in the supply of rakes to these locations.

Another logistical bottleneck is that the average loading time at thermal power plants is around 6-7 hours at present. This is very high, according to railway officials.

“If the loading time is halved to around 3-4 hours, rakes can be reused and supply can be increased even more, especially in shorter distances,” a senior government official said.

Way ahead

The government is planning to strengthen IR’s infrastructure and has stressed on commissioning 14 critical coal-evacuation railway projects.

These projects include the Tori-Shivpur Rail Line (on deposit basis), the Jharsuguda-Barpali-Sardega Rail Link at Ib-Valley Coalfield of MCL in Odisha (on deposit basis) as well as Shivpur – Kathautia Rail Line (through a Special Purpose Vehicle).

Projects on a deposit basis are developed using non-railway funds.

The government, in 2022-23, has also come out with an order for nearly 90,000 wagons to be supplied in the next three years, in order to meet the shortfall of wagons in the industry.

The national transporter is also looking to acquire 6,000 wagons in this financial year, which will be solely used for coal transportation.

The dedicated freight corridors are also expected to help decongest railway tracks and ease supply-chain bottlenecks.
