132 Plants Against a Target of 5,000: India Mandates Biogas Before It Can Make It
A blending obligation rising to 5% by FY29 turns voluntary demand into law — but Germany's 'corn mania' is the warning India's maize numbers are already echoing
What happened
Energy-security answers usually stop at the import bill. The examinable tension here is between two government objectives that are both succeeding: blending targets are being met ahead of schedule, and crop diversification is going backwards. Learn this as the clearest current instance of a policy externality inside Indian agriculture — where the price signal created by an energy mandate reorganises what farmers plant, and the food-security cost appears in a different ministry's numbers.

Compressed biogas is produced by anaerobic digestion of organic matter — agricultural residue, cattle dung, municipal solid waste, press mud, sewage — followed by purification to raise methane content and compression for use as a transport or piped fuel.
●Because it is chemically similar to CNG, it can be blended into existing city gas distribution networks without new infrastructure at the consumer end.
●SATAT (Sustainable Alternative Towards Affordable Transportation), launched in 2018 by the Ministry of Petroleum and Natural Gas with oil marketing companies as assured offtakers, targeted 5,000 CBG plants by 2023; only 132 had been completed as of 3 June 2026.
●GOBARdhan (Galvanising Organic Bio-Agro Resources Dhan), under the Department of Drinking Water and Sanitation, provides grants of up to ₹50 lakh per district.
●The National Biofuels Coordination Committee approved CBG blending in 2023 and a phased mandatory obligation was announced in the 2024 Budget: 1 per cent in FY26 rising to 5 per cent by FY29, applying to CNG for transport and PNG for domestic use.
●Related support includes ₹564 crore for biomass collection machinery and ₹994 crore for grid-connection pipelines.
●On the liquid-fuel side India achieved 20 per cent ethanol blending by December 2025, ahead of its 2030 target.
●Global biogas production remains concentrated — roughly 90 per cent in Europe, China and the United States.
A blending mandate creates demand by law; it cannot create digesters, feedstock aggregation or grid connections — which is why 132 plants now face an obligation designed for thousands.
◎ In Simple Words
India buys most of its oil and cooking gas from abroad, much of it shipped through one narrow sea passage. To reduce that dependence, the government wants gas made from farm waste, cow dung and other organic matter — called compressed biogas — mixed into the gas supply. From this year, companies must include 1 per cent of it, rising to 5 per cent by 2029. The problem is that very few such plants exist: the plan was 5,000 by 2023, but only 132 have been built. There is also a catch. Making fuel from crops has made maize very profitable, so farmers are growing maize instead of pulses and oilseeds — which India then has to import.

Frequently Asked
· People also askWhat is compressed biogas and how is it made?
Compressed biogas is produced by anaerobic digestion of organic matter — agricultural residue, cattle dung, municipal solid waste, press mud or sewage — then purified to raise methane content and compressed. Because it is chemically similar to CNG, it can be blended into existing city gas networks without changes at the consumer end.
Prelims · GS3That drop-in compatibility is why a blending obligation is technically feasible: no new distribution infrastructure or appliances are required, only supply.
SOURCE Ministry of Petroleum and Natural Gas
What is SATAT and how far has it got?
SATAT — Sustainable Alternative Towards Affordable Transportation — was launched in 2018 by the Ministry of Petroleum and Natural Gas with oil marketing companies as assured offtakers of compressed biogas. It targeted 5,000 CBG plants by 2023; as of 3 June 2026 only 132 had been completed.
Prelims · GS3The shortfall reflects high capital costs, difficulty aggregating dispersed biomass, weak access to formal credit and limited pipeline and grid connectivity.
SOURCE Ministry of Petroleum and Natural Gas
What is the CBG blending obligation?
A statutory requirement on city gas distribution companies to blend compressed biogas into their supply — 1 per cent from FY26, rising to 5 per cent by FY29. It applies to CNG for transport and PNG for domestic use, and converts what was voluntary offtake into a legal obligation.
GS3 · EconomyIt was approved by the National Biofuels Coordination Committee in 2023 and announced in the 2024 Budget. The design question is that it acts on demand while the binding constraint is supply.
SOURCE National Biofuels Coordination Committee
Why is maize cultivation a concern here?
Biofuel demand made maize highly profitable — maize-based ethanol prices grew at 11.7 per cent CAGR from FY22 to FY25 and yields rose from 2.56 to 3.78 tonnes per hectare. The Economic Survey 2026 records maize displacing pulses, oilseeds, soybean, millets and cotton in states including Maharashtra and Karnataka.
GS3 · AgricultureSince India imports pulses and edible oils, an energy policy that reduces crude imports by increasing pulse and edible-oil imports does not straightforwardly improve the external position.

What was Germany's 'corn mania' and why does it matter to India?
Germany's Renewable Energy Sources Act of 2000 made biogas from energy crops so profitable that maize monoculture spread widely, shifting land away from food crops. The government eventually capped the share of maize permitted in biogas feedstock.
GS3 · ComparativeThe lesson is that feedstock composition must be regulated from the outset, because an incentive paid per unit of biogas will select the highest-yielding energy crop regardless of its food opportunity cost.

Why does India want biogas for energy security specifically?
Because its exposure is concentrated at a single maritime chokepoint — about 90 per cent of India's LPG imports transit the Strait of Hormuz — and domestically produced biogas substitutes precisely for the gaseous fuels most affected, unlike solar or wind.
GS3 · EnergyIt also converts waste-management liabilities — crop residue burning, unmanaged cattle dung, municipal organic waste — into an energy input, addressing an air-quality problem and an energy problem with one instrument.
