Currently the PLFs of the domestic coal based power plants in India are low, which implies lower profits, this has happened because India witnessed growth in supply of power plants at an unprecedented level between 2011 and 2016, the supply of power grew at 14.5% in the period. The PLFs dropped further due to the push of the 2014 elected government to increase power generation via Renewable Energy.
More power dispatches started to happen from the RE sources which displaced conventional coal based power.
Currently India has ~40 GW of idle power it has no PPAs signed with the DISCOMs or it is in the IBC-NCLT. These newer plants were built mostly by the private companies which are now stuck because they don’t have PPAs or FSA (Fuel Supply Agreements) from Coal India.
