The full incentive stack for compressed biogas under GOBARdhan and SATAT: assured offtake, capex support, fertiliser-side revenue and the FCO gazette moves that enable it — from the official 70-circular register.
The CBG Incentive Stack — Every Leg of a Biogas Plant De-risked
Update, 9 October 2026. Since this piece was written, a single national scheme has been laid over the stack below. The GOBARdhan scheme was approved by the Cabinet on 6 August 2026 with ₹23,731 crore for FY2026-27 to FY2035-36, and launched with a portal and handbook on 1 October 2026, with the Ministry of Petroleum and Natural Gas as the single nodal ministry. Per the launch coverage it sets an administered CBG price of ₹2,110 per MMBtu, offers capital assistance of up to ₹2 crore per tonne-per-day of capacity for eligible greenfield plants and up to 80% of the cost of pipelines linking CBG clusters to trunk lines, adds credit-guarantee support and a challenge fund, and targets roughly ten times today’s output. Several legs listed below (offtake, pricing, capital subsidy, pipelines, finance) now sit inside this one scheme; the section-by-section figures have not been revised. Source: PIB release of 1 October 2026 (PRID 2317937); details as reported by Swarajya and PSU Watch.
Corrections, 14 October 2026. A check of the 9 October update and the figures below against press and agency summaries (the PIB release itself could not be opened) found several details that could not be confirmed or that differ. (1) The administered price of Rs 2,110 per MMBtu is confirmed by several outlets, but it excludes taxes and compression charges, replaces Rs 1,478 per MMBtu, and is reported as Rs 98 or Rs 105 a kilogram depending on the calorific basis. (2) Reports date the price to 1 September 2026 and the operational guidelines to 15 September; the 1 October portal launch rests on one source, and the release number given in the update did not appear in any result. (3) Capital assistance is reported as up to Rs 2 crore per tonne a day at Cabinet stage but Rs 1.25 crore, capped at Rs 30 crore a project, in the guidelines. (4) The “80% of pipeline cost” support was not found in any source. (5) The Rs 54 a kilogram SATAT basis below is unsupported; the last official per-kilogram figure found is Rs 77.4, including Rs 8 for compression, for 2025. (6) The statement that 5% GST applies to CBG sales could not be confirmed; the 5% rate found applies to biogas plants and devices since 22 September 2025. The ~Rs 0.59 a kilogram effect of the blending obligation on the CNG pump price predates the new price and should be rechecked. See the companion piece, “Biogas Is a Priority-Sector Loan. The 43% Higher CBG Price Is Worth About 50 Times the Cost of the Repo Hike”, for the sources. The original text below is unchanged apart from this note.
Updated 7 November 2026. The CBG blending obligation’s first year, FY2025-26, is reported as met: about 1.05% against the 1% target, per Swarajya, though PNGRB’s own 6 August 2026 sales figures (111.48 of 12,033 million standard cubic metres) work out to about 0.93% by this blog’s arithmetic. The obligation steps up to 3% for FY2026-27. Sources: Swarajya, PNGRB, 6 August 2026 (search summary only).
1. Assured offtake & pricing (the revenue floor)
- SATAT procurement price (MoPNG, 20-May-2022 + 15-May-2025 revision): OMCs guarantee CBG offtake at an assured ex-plant price (₹54/kg basis in the model, excl. 5% GST), with long-term agreements; the May-2025 circular revised the methodology and linked pricing under the synchronization scheme.
- CBG–CGD Synchronization Scheme (Apr-2021, extended Oct-2023 and Mar-2026): CBG is injected/co-mingled directly into city-gas networks and treated as fungible with natural gas — the plant sells into the grid rather than trucking to a pump.
- CBG Blending Obligation (CBO) (MoPNG, 27-Feb-2024): mandatory blending in CNG(T)/PNG(D) — 1% FY25-26 rising toward 5% by FY28-29. This is demand assurance by decree; the analysis shows even 5% moves the CNG pump price only ~₹0.59/kg.
2. Capital subsidy & viability funding
- MNRE Waste-to-Energy / National Bioenergy Programme (Nov-2022, revised Jun-2025, supplementary budget Sep-2025): central financial assistance per unit of CBG capacity, capped per project.
- SBM 2.0 Viability Gap Funding for bio-methanation (MoHUA, revised cost norms 12-Nov-2025): VGF for municipal-waste CBG plants.
- SASCI — Special Assistance to States for Capital Investment 2026-27 (Department of Expenditure, Mar-2026 + MoPNG May-2026 guidelines): capital assistance to states tied to CBG-sector reforms — the newest money on the page.
- GOBARdhan (SBM-Grameen) umbrella: district-level support for community/cluster biogas plants.
3. Infrastructure & feedstock support
- Development of Pipeline Infrastructure (DPI) scheme (MoPNG, Mar/Jun-2024, amended Jan-2025, revised Aug-2025, extended Feb-2026): funds the connecting pipeline from plant to CGD grid — the offtake bottleneck.
- Biomass Aggregation Machinery (BAM) scheme (Feb-2024, revised Jul-2025): assistance for paddy-straw/biomass collection machinery.
- Crop Residue Management guidelines (DA&FW, 2023/2024): channels parali (stubble) to CBG plants as feedstock.
4. The fertiliser leg (digestate = second revenue stream)
This is the deepest circular trail — 15+ of the 70 circulars:
- FCO amendments: FOM recognised Jul-2020, LFOM May-2021, spec relaxations 2023 (moisture, C:N, authorization exemption), culminating in the "Organic Carbon Enhancer" Schedule VIII category (17-Feb-2025 + 27-Mar-2025 specs — gazette CG-DL-E-29032025-262118: defined on organic carbon 12–14% + heavy metals only, no NPK/C:N/sieve requirement — built so CBG digestate can actually pass).
- Bulk Sale Notifications I–VII (Nov-2023 → Feb-2026): named plants may sell FOM/LFOM in bulk directly to farmers for 3 years, bypassing fertiliser-dealer licensing.
- Market Development Assistance (MDA) (DoF, Sep-2023 guidelines + SOPs/iFMS/DBT machinery through 2024-25): ~₹1,500/tonne support on FOM/LFOM/PROM sold — a per-tonne subsidy on the digestate.
- ICAR Package of Practice (Jul-2024): official agronomic guidance legitimising FOM use on crops.
5. Finance access
- Priority Sector Lending (RBI, Sep-2020): CBG plants qualify — cheaper, mandated bank credit.
- Agriculture Infrastructure Fund (Oct-2020/Jan-2023): interest subvention + credit guarantee eligibility.
- AHIDF (DAHD, Apr-2022): dung-based plants eligible under the animal-husbandry fund.
- NCDC coop route: exists but — per the supply analysis — is 96.5% working capital in practice.
6. Tax & carbon
- 5% GST on CBG (vs full excise+VAT on liquid fuels).
- Central excise exemption on CBG-blended CNG (Feb-2023 budget): the blended portion isn't taxed twice.
- Carbon-credit eligibility (MoEFCC, 20-Feb-2023): CBG plants can monetise credits under the Paris-Agreement framework — a third revenue leg.
7. Regulatory easing & standards
- CPCB re-categorisation (2021, Feb/Mar-2025): friendlier pollution-control classification for CBG plants.
- IS 16087:2025 (Aug-2025 revision): the Bio-CNG quality standard that makes CBG legally fungible with CNG — the technical basis of "energy parity per kg".
- MoRTH notification (Jun-2015): bio-CNG authorised as an automotive fuel — the foundational circular.
8. State policies layered on top
UP Bio-Energy Policy 2022, Bihar 2023 (+2025 amendment), Rajasthan & AP Integrated Clean Energy 2024, Assam 2025, MP biofuel scheme Apr-2025, and the newest — Chhattisgarh CBG Policy, 8-Jul-2026 — typically adding capital subsidy top-ups, land, stamp-duty and electricity-duty waivers. MoPNG's Model State CBG Policy (Apr-2026) now gives states a template.
The pattern worth noting: the stack de-risks every leg of the CBG business model — feedstock (BAM/CRM), capex (MNRE/VGF/SASCI), debt (PSL/AIF/AHIDF), gas revenue (SATAT floor + CBO mandated demand + DPI evacuation), digestate revenue (FCO Schedule VIII + bulk sale + MDA), and carbon revenue — and it's all on-budget and ex-plant, the exact contrast with ethanol's hidden consumer-side funding. The circular cadence also shows acceleration: roughly half the register is dated 2025-26.

What would fix this
- The Petroleum Ministry should publish one consolidated, dated register of every central CBG incentive with the amount sanctioned and disbursed under each in the latest year, so that a stack built from some 70 circulars, half dated 2025–26, can be judged on money paid rather than schemes announced.
- The Petroleum Ministry should publish CBG Blending Obligation compliance by city-gas entity each year — volume blended against the 1% rising to 5% obligation, so that ‘demand assurance by decree’ can be checked against what was actually bought.
- MNRE should publish central financial assistance sanctioned and released, plant by plant, under the National Bioenergy Programme, so that capital support can be matched to plants that actually commission and produce.
- NCDC should publish the split of its lending to cooperative CBG and biogas projects between term loans and working capital, so that the finding that the cooperative route is 96.5% working capital in practice is tracked and any shift towards project finance is visible.
