NTPC has invited bids for procuring 1,000 metric tonnes per day of agro residue based fuel for its 2,650 mw Dadri power plant in the National Capital Region as part of initiatives to help clean air and provide farmers with an alternate to burning crop residues, a major contributor to pollution. The tender seeks supply for two years. A capping price of Rs 5,500 per metric tonne has been kept for agro residue based pellets and Rs 6,600 per tonne for pellets or briquettes of torrefied agro Residue, the spokesperson said. Open burning of biomass has been identified as one of the major cause of poor air quality in Northern India, especially in and around Delhi. NTPC has initiated a programme to consume agro residue based fuel for firing in their power plants along with coal. Subsequently, the government has also come with an advisory to fire 5%-10% of agro residue based fuel in thermal power plants.
