Mounting protests over the death of four miners, paralysing production at one of the largest coal mines under Coal India Limited (CIL) in Odisha, has started taking a toll on power generation. Hit by a coal shortage, the country’s largest power producer, NTPC, has been forced to progressively shut down three units at its 3 000 MW super thermal power plant since the protests over the death of the miners started to gather momentum, leading to a shortage of coal supplies from CIL mines.
