GOBARdhan's Tenfold CBG Bet: Pricing Out Revenue Risk, Not Just Capital Cost

The Tenfold Jump Is a Bet on Bankability, Not on Biogas Technology

India produces about 0.4 mmscmd of compressed biogas (CBG) today. GOBARdhan, a ₹23,731-crore scheme running from 2026-27 to 2035-36, aims for 4-6 mmscmd. That reads like an engineering target. It is really a finance target and the person it is written for is not the farmer or the motorist but the loan officer.

Why

SATAT stalled at the letter stage SATAT, launched in October 2018, planned 5,000 CBG plants producing 15 million tonnes a year by 2023-24. By 31 October 2022, oil and gas marketing companies had issued 3,694 Letters of Intent, yet only 38 plants had been commissioned.

Thousands of entrepreneurs wanted to build plants, but very few did. Technology was not the bottleneck. Turning dung, crop residue and food waste into gas through anaerobic digestion is a mature process. The bottleneck was in the developer's project report:

• A CBG plant has a large, fixed upfront cost.
• It has two uncertain sources of revenue: the gas and the fermented organic manure left over.
• A Letter of Intent shows that a buyer is interested. It does not fix a price for ten years and it does not commit the buyer to taking every kilogram. A bank sizing a loan cannot work out whether the plant can repay when it cannot forecast the plant's revenue. So the bank either declines or charges a higher interest rate to cover the uncertainty. A plant with thin margins then fails before it is built.

What

GOBARdhan changes in that calculation The scheme goes straight at the revenue problem:

• Assured offtake of up to 100% of eligible output removes the risk of not being able to sell the gas.
• An administered price of ₹2,110/MMBtu (about ₹98/kg), guaranteed until 2036, removes price risk for roughly the life of a typical project loan. Together, these turn a plant that sells into an unpredictable market into something closer to an annuity, with a predictable income stream. That is what lets lenders offer cheaper, longer loans. For a capital-heavy plant, cheaper debt matters more than a one-time grant. Capital assistance still exists, but a subsidised plant that cannot sell its gas will still default, while an unsubsidised plant with guaranteed revenue can still borrow.

Who carries the risk now The risk has not disappeared; it has moved to other parties.

• Gas buyers must now take output at a fixed price. If that price is above what other gas costs, the gap falls on them and through them possibly on consumers or the exchequer.
• Feedstock supply becomes the new constraint. Bulky, seasonal biomass has to arrive at the plant reliably, every day, for a decade. The farmer who sells crop residue instead of burning it is meant to become an energy provider as well as a food grower, an Urjadata as well as an Annadata. That farmer is now the plant's most important supplier. Biomass supply chains are where the next failure could happen.

Exam insight: GOBARdhan is a clear case of the state fixing a market failure in demand certainty, not a technology gap. If the tenfold target delivers ₹40,000 crore in import savings and helps move gas towards 15% of the energy basket by 2030, it will be because lenders followed the price guarantee, not because the subsidy paid for the equipment.
