The plant has a bowl mill and can only use biomass that is torrefied (preheated at 250300 degrees Celsius to remove volatile matter and reduce moisture). There are even fewer suppliers of torrefied pellets in the market. Nabha Thermal Power Plant (LT, Punjab), similarly, has had no takers so far for its tender on the supply of pellets.
