India holds an estimated 28 GW of untapped power potential from agricultural residue, a key resource for reducing coal reliance and stubble burning. While the SAMARTH mission mandates biomass co-firing in thermal plants, the sector faces significant operational hurdles, including supply chain fragmentation, storage shortages, and payment delays that affect long-term feasibility.
India currently holds an estimated 28 GW of untapped power generation potential from agricultural residue, such as crop stubble. While this capacity is significant enough to offset a portion of the nation’s peak electricity demand and reduce coal dependency, translating this potential into active power generation remains a complex challenge for the energy sector.
At the core of the government’s strategy is the 'SAMARTH' mission, which mandates that coal-based thermal power plants blend biomass pellets with coal. This policy aims to create a sustainable market for crop residue, transforming a pollutant into a usable fuel source. For many thermal plants, this requires retrofitting existing infrastructure to handle biomass, a move that is essential for meeting environmental mandates to curb air pollution, particularly in the National Capital Region.
However, the gap between potential and execution is wide. The primary obstacle is the logistics of the biomass supply chain. Unlike coal, which is extracted from mines and transported via established rail and road networks, agricultural residue is seasonal and highly dispersed. Harvesting takes place in tight windows, and the lack of localized storage infrastructure often forces farmers to burn stubble instead of collecting it. Surveys in major agricultural states show that many farmers pay out-of-pocket for residue management, highlighting the need for efficient aggregators and transport solutions.
Operational risks are also prominent for pellet manufacturers and power plant operators. The biomass feedstock—often crop waste—is susceptible to moisture and quality fluctuations, which can affect boiler performance in thermal plants. Furthermore, the industry faces profitability pressures caused by volatile raw material pricing and frequent payment delays from larger utilities. Without long-term procurement contracts that ensure stable pricing and timely payments, many small-scale operators struggle to justify the heavy investment required for collection, processing, and storage facilities.
Investors looking at this sector should monitor developments beyond just capacity announcements. The real progress will be measured by improvements in the supply chain, such as the creation of reliable feedstock aggregation centers and more flexible payment structures for pellet suppliers. As thermal power plants work to meet their mandatory blending requirements, the success of the biomass sector will depend on stabilizing the rural bio-economy and addressing the seasonal and logistical bottlenecks that currently prevent this 28 GW potential from becoming a consistent part of the national power grid.
