Tangedco’s import is maximum even though it has the lowest thermal capacity among the large distribution public companies
Tangedco imported a total of 2,82,000 tons of coal between April and June this year after the Center asked all state-owned electricity distribution companies and private generators to import coal and mix it with local coal.
Tangedco’s import is maximum while it has the lowest thermal capacity among large public distribution companies. Mahagenco (Maharashtra discom) comes next with 2.56,000 tons, with the total import from all states being 6.05,000 tons.
The Union Department of Energy, in an April 28 letter, advised Central Gencos (Gencos), State Gencos and Independent Power Producers (IPPs) to import coal from blending purposes in fiscal year 2022-23.

In addition, to ensure minimum coal stocks at power stations before the onset of the monsoon, the ministry advised all Gencos to complete the placement of coal import rewards by May 31.
The Ministry has informed Gencos that domestic coal will be allocated proportionally to each of them based on the likely availability of domestic coal from CIL/SCCL from June 1 and that the shortfall is to be made up by blending the imported coal.
Following these two orders, Tangedco like other Gencos started to import coal and it landed at the port of Ennore.
“Electricity demand started to peak this year from the end of March. We faced a shortage of coal and electricity was also not available in the power exchange, as generators also faced a shortage of coal,” said a senior Tangedco official.
The coal inventory fell to one day or less in some thermal units in April and May. “We had to import as much as possible to meet the demand and ensure the power supply without any power cuts. It was only after the start of wind power generation that we did not face a shortage of coal as wind power was available to cope with the evening peak,” the official said.
Until July 22, the old thermal power plants of Tuticorin and the old thermal power plants of Mettur did not have a stock of imported coal. But the North Chennai and Mettur 600MW units have 30.3 metric tons and 135.5 metric tons of imported coal.

“Until September, we will have enough power from wind and solar sources. As many as 80 million units of solar and wind power are produced every day and it has become a very important power source in the world. ‘State this year,’ the official said.
After September, demand will only be met with thermal and other sources. “We are confident to meet demand even without wind as two units of Kudankulam will start generating power and together with other central and thermal units will also supply power,” the official said.
