Yamuna Nagar thermal unit synchronization further delayed
According to sources, the unit was lighted up last week for synchronization but have to be closed again following high vibrations in the turbine. As some bolts of bearing cover have been damaged, turbine is again being checked for some oil leakage.

300 MW Yamuna Nagar thermal unit, which was expected to be revived by middle of October has been further delayed following vibrations in the turbine.

According to sources, the unit was lighted up last week for synchronization but have to be closed again following high vibrations in the turbine. As some bolts of bearing cover have been damaged, turbine is again being checked for some oil leakage.

It may be mentioned that complete overhauling of this unit and auxiliary system was carried out under the direct supervision of Chinese engineers for a period of more than 6 months. The unit turbine rotor was received back at Yamuna Nagar after repairs at Baroda/ Mumbai in September this year.

Meanwhile, the damaged rotor of other unit which was sent to China for repairs has been dispatched after final inspection. The rotor components are expected to reach Indian port by last week of December. The unit may come early next year.

The coal shortage has hit all the running thermal plants in the state except Yamuna Nagar thermal which is under long forced shutdown. As per latest Central Electricity Authority (CEA) report, coal stock at NTPC and CLP plants at Jhajjar was just sufficient for 2 days. The coal stock at Khedar and Panipat is just sufficient for 4 days. One 660 MW unit at Jhajjar is under shutdown for last three weeks due to coal shortage.

The power demand in state is around 1331 lakh units and there is no power shortage, as per CEA daily report. One 600 MW unit at Khedar is likely to be revived in next few days after clearance of technical fault. One Panipat unit is under scheduled annual maintenance. Meanwhile NTPC has reportedly commissioned third 500 MW unit at Jhajjar.

Overall in the country, there are 30 thermal plants which have less than 4 days coal stock which comes under super critical category. 50 thermal plants including super critical category have less than a week coal stock. 7 thermal plants in country have less than 4 days coal stock as they failed to import coal. There are at least 4 plants which have zero coal stock.
