What to check before you quote it

The CBO, approved by the National Biofuels Coordination Committee, requires CGD entities to blend CBG into CNG for transport and PNG for domestic use: 1% in FY2025-26, 3% in FY2026-27, 4% in FY2027-28 and 5% from FY2028-29. It creates demand; it is not itself installed capacity.

In FY2025-26 CBG sales into the CNG transport and PNG domestic segments reached 1.05% against the 1% target, per the Petroleum Minister's written reply of 6 August 2026. But the CBO is an obligation on CGD entities to blend, not proof that enough CBG capacity has been built - India had roughly 217 commissioned plants against a 5,000 target at the same date.

It converts voluntary demand into a legal obligation on CGD entities, which improves offtake certainty - but the volumes are consumption-linked targets, not a guarantee that supply exists. Petroleum Minister Hardeep Singh Puri stated the CBO would encourage investment of around 37,500 crore rupees and facilitate 750 CBG projects by 2028-29, which is a projection rather than a commitment.

As of 6 August 2026 the GOBARdhan portal recorded 1,908 registered CBG and Bio-CNG plants, of which 217 were commissioned - producing 0.4 MMSCMD - with 339 under construction. Registered and commissioned are very different numbers and must never be conflated.

SATAT's original aspiration was 5,000 CBG plants. Actual commissioned plants - 217 as of mid-2026 - remain a small fraction of it, so it is a target rather than achieved capacity, and should be modelled against commissioning trends rather than quoted as a fleet size.

Reliance laid the foundation on 2 April 2025 for the first of a planned 500 plants - Kanigiri in Andhra Pradesh, 475 acres, 139 crore rupees, 100 TPD - within a 65,000 crore rupee state programme. Adani Total Gas runs Barsana at 600 TPD feedstock; GPS Renewables builds EPC at scale with IOC and BPCL joint ventures; EverEnviro operates an Indore MSW plant of about 15 TPD. Most of the large figures are planned capacity, not operational.

They are policy ambitions, not committed capacity. With 217 plants commissioned against a 5,000-plant target the delta is enormous, and closing it depends on feedstock, financing and execution rather than on the target being restated. Model against commissioning trends.

Large players - Reliance, Adani Total Gas, GPS Renewables, EverEnviro, and IOC and IGL joint ventures - are building multi-plant portfolios, which favours standardised replicable designs and creates eventual consolidation potential. Portfolio counts are planned rather than operational, so read them as pipeline, not fleet.

Under REPowerEU the EU targets 35 bcm - about 350 TWh - of annual biomethane production by 2030, against roughly 3 bcm produced today, backed by an estimated 37 billion euro investment need. It is an ambition comparable in scale, and in evidence gap, to India's CBG push.

The IEA's 2025 outlook sees demand roughly tripling in India. Earlier IEA analysis found that biomethane could cost-effectively meet 10% of India's natural gas demand today, rising to almost two thirds by 2040, with India's biomethane potential around 35 bcm by 2040 in its sustainable scenario.

CBG historically faced a double-taxation problem at the blending point. Budget 2026-27 exempted central excise duty on the biogas or CBG portion of blended CNG, removing a barrier that had made CGD entities reluctant to pay the full rate. GST still applies and should be modelled explicitly in the DPR.

The Kalaburagi-Vijayapura geographical area is served by AG&P Pratham / THINK Gas, holding 25-year PNGRB authorisation across several southern states. Kalaburagi has no trunk gas pipeline, so CBG there is cascade and retail oriented rather than injection oriented.

Maharashtra, Uttar Pradesh, Punjab, Gujarat and Madhya Pradesh are among the most active, driven by sugar - press mud and spent wash - paddy straw and dairy feedstocks, and several carry dedicated CBG or bioenergy policies. Reported commissioned counts put Uttar Pradesh around 40, Gujarat around 25 and Maharashtra around 24, but state counts move frequently and should be checked against the live portal.

Karnataka administers renewable energy largely through KREDL and its Renewable Energy Policy 2022-27, without a dedicated bioenergy agency. Its Industrial Policy 2025-30 offers extra incentives - up to 5% for extremely backward regions and 3% for backward regions - which covers Kalyana Karnataka and Kalaburagi. Land is accessed by lease.

Unlike manure and waste pathways, there is no robust peer-reviewed life-cycle assessment of Napier-based CBG in Indian conditions. Existing work is largely lab and pilot yield studies, so the carbon intensity of a Napier-fed plant - accounting for cultivation, fertiliser, water and land use - is genuinely uncertain and should be stated as such.

Projects can use accelerated depreciation and input GST credits, and Budget 2026-27 exempted central excise on the CBG portion of blended CNG, improving CGD willingness to pay the full rate. MSME status can unlock further benefits. Exact rates should be confirmed with a tax adviser rather than taken from a summary.

The GGSS is a tariff-based support scheme for biomethane injected into the grid, funded by a levy on gas suppliers - a subsidy model distinct from both India's administered procurement price and the US credit markets. Current tariff details should be checked against the scheme documentation before being quoted.
