Central & state support for CBG in West Bengal
Under the GOBARdhan National Unified Scheme (₹23,731 crore, FY 2026-27 to FY 2035-36), eligible greenfield CBG projects in West Bengal can receive capital assistance of up to ₹2 crore per TPD, along with assured offtake, a pricing framework and support for pipeline connectivity. The CBG blending obligation for CNG and PNG creates steady demand. State-level industrial, renewable-energy or bioenergy policies may offer further incentives. These change with notifications, so we check the current provisions for West Bengal while preparing your DPR.
