Despite a growing pipeline and government support, India’s compressed biogas sector remains fragmented and constrained by high costs and logistical challenges. With significant potential and diverse off-takers, the sector’s ability to transition from ambitions to reality hinges on overcoming delivery obstacles and scaling projects from small plants to larger, commercially viable operations.
India’s compressed biogas sector is expanding steadily, but the market is still shaped more by ambition than scale. Renewable Watch Research, in its latest market snapshot for March to June 2026, says the country has 1,847 tracked CBG projects across commissioned, under-construction, yet-to-start and approved stages. The appeal is clear: CBG can replace compressed natural gas, LPG, diesel and furnace oil across transport, cooking, industrial heat and captive power, giving it a role in both energy security and waste management.
The underlying resource base is substantial. NITI Aayog has estimated India’s all-India biopower potential at 42 GW, including 28 GW from biomass and 14 GW from cogeneration bagasse, and government schemes such as SATAT and GOBARdhan have helped push the sector forward, according to Renewable Watch Research. Yet the market remains weighted towards smaller plants: the largest share of commissioned projects falls below 5 tonnes per day, while under-construction projects are most often in the 5-10 tonnes per day band. That pattern suggests the economics still favour localised facilities with simpler feedstock sourcing and lower upfront costs.
The project pipeline is concentrated in a handful of states. Uttar Pradesh and Gujarat lead both commissioned and under-construction counts, followed by states including Maharashtra, Haryana, Rajasthan and Madhya Pradesh, with Tamil Nadu, Punjab, Karnataka and Jharkhand also prominent in the operational base. Renewable Watch’s data point to a market that is spreading geographically, but not yet evenly.
Despite that breadth, the sector is still fragmented. Renewable Watch says no single developer dominates supply or sales, although large groups and public-sector entities feature prominently. Those include Reliance Group, Blue Planet Environmental Solutions, the state oil marketing companies and EverEnviro Resource Management, alongside district-level agencies and sanitation bodies. On the demand side, major offtakers include GAIL, BPCL, HPCL, Indian Oil, Indraprastha Gas and Gujarat Gas, with other buyers such as Bhagyanagar Gas, Adani Total Gas, Reliance BP Mobility, Torrent Gas, Maharashtra Natural Gas, Avantika Gas and AG&P Pratham.
The broader policy case for CBG is being reinforced by research and recent corporate financing. Studies cited by StudyIQ, ScienceDirect and Springer describe CBG as a product of anaerobic digestion that can help cut open burning, reduce dependence on imported fuels and support a circular economy, while also noting persistent bottlenecks around feedstock logistics, regulation and by-product monetisation. In July, Mercom India reported that GPS Renewables raised ₹6.35 billion to support its project pipeline, a sign that private capital still sees room for growth even as execution risks remain high.
For now, the biggest constraint is not market interest but delivery. Renewable Watch says the sector is held back by high production costs, weak feedstock supply chains and difficulty in earning revenue from by-products. The key question is whether more projects move from announcement to commissioning. If they do, CBG could become a meaningful part of India’s renewable mix; if not, the market may stay stuck in the pipeline.
