NTPC Limited, a Central Public Sector Undertaking (CPSU) under the Ministry of Power (MoP) has successfully demonstrated co-firing of biomass at its Dadri Thermal Power Station over a period of time. Following steps have also been taken by MoP towards use of bio-mass in generation from the coal based thermal power plants (TPPs):
i. In November, 2017, MoP issued a policy regarding “Biomass Utilization for Power Generation through co-firing in Coal-based power plants” wherein all fluidized bed and pulverized coal units (coal based TPPs) located in India were advised to endeavour to use 5-10% blend of biomass pellets made, primarily, of agro residue along-with coal after assessing the technical feasibility, viz. safety aspects etc.
ii. In order to further promote use of biomass pellets in coal based TPPs, MoP revised the above policy in October, 2021 to mandatorily co-fire the suitable biomass pellets in the range of 5% to 7% in all coal-based power plants depending upon their type of milling system.
iii. MoP has established a National Mission on Use of Biomass in Thermal Power Plants (NMBTPP) in July, 2021 to expedite the utilization of biomass in TPPs.
iv. A specialized Sub-Group has also been constituted under the aegis of NMBTPP to deal with Research and Development (R&D) on Boiler design and safety aspects for higher amount of co-firing of biomass.
