The coal stock at 27 thermal plants is less than 4 days and western region is worst hit as 12 plants with super critical coal stock are from this region. 5 thermal plants in each region are having coal stock of less than 4 days. In northern region, Rajpura thermal plant in Punjab, Rihand and Anapara C in Uttar Pradesh have reported nil coal stock .
The main reason given for less coal stock is regulated coal supply by Coal India due to several constraints. The reason may be less allocation of coal, transportation problems of Railways and inability of new plants to handle coal.
In case of Punjab, the coal stock at state run thermal plants at Lehra Mohabatt and Ropar is sufficient for 6 and 12 days respectively. In case of private thermal plants at Rajpura and Talwandi Sabo stock is left for 1l and 2 days respectively.
The coal position in all the three thermal plants of Haryana is comfortable. Panipat thermal has 31 days coal stock while Yamuna Nagar and Khedar have 28 days coal stock.
Meanwhile NTPC has reported that the six thermal plants, with a total generation capacity of 17,000 MW, have "reached at a critical level of coal" sufficient for less than two days.
