Grain-based feedstocks have become the primary driver of India’s ethanol supply, accounting for 70% of the 895 crore litres delivered by August 2026. This move marks a significant diversification from sugar-based sources to improve energy security. While the transition stabilizes supply, stakeholders are keeping a close watch on potential food inflation, input cost volatility for distilleries, and evolving government blending policies.
Data from the All India Distillers' Association (AIDA) for the 2025-26 Ethanol Supply Year (ESY) shows a major change in how India produces fuel ethanol. Out of the 895 crore litres of ethanol supplied through August 2026, grain-based feedstocks have emerged as the dominant source, providing 624 crore litres, or roughly 70% of the total. This highlights a clear pivot away from the traditional reliance on sugarcane-based feedstocks, which contributed 271 crore litres in the same period.
Maize and Rice Take Center Stage
Within the grain segment, maize has become the single largest contributor to the supply, accounting for 345 crore litres. This is supported by surplus rice sourced from the Food Corporation of India (FCI), which contributed 214 crore litres, along with 64 crore litres from damaged food grains. In contrast, the sugar sector’s contribution has been more limited, comprising 149 crore litres from direct sugarcane juice, 107 crore litres from B-heavy molasses, and 15 crore litres from C-heavy molasses.
This shift is strategic for the national energy blending program. By diversifying the materials used to create ethanol, the industry aims to protect its supply chain from the volatility often seen in the sugar sector. Sugarcane production is frequently affected by monsoon patterns, variable crop yields, and government-mandated export policies, which can disrupt ethanol production schedules.
Business and Economic Risks
While the diversification is a positive step for supply stability, it brings new challenges for distillery companies. One primary concern is the pressure on profit margins. Distilleries using grain-based feedstock are now more exposed to the price fluctuations of maize and broken rice. Unlike long-term sugar contracts, grain prices can be sensitive to seasonal harvests and government procurement priorities.
Another critical factor is the food-versus-fuel trade-off. As India increases its reliance on grains for energy, concerns regarding food inflation and supply availability for human consumption have surfaced. The government must balance its biofuel targets with the need to keep food prices stable, which introduces regulatory uncertainty. Any sudden policy changes, such as restrictions on the use of certain grains for ethanol production to control food inflation, could directly impact the operations and profitability of companies in this space.
What Investors Should Monitor
The industry has reached about 85% of its 1,048 crore litre contracted volume for the year, but the long-term sustainability of this model remains to be proven. Moving forward, the key factor for investors will be the actual utilization of this new capacity. The success of the ethanol program depends on demand-side drivers, such as the adoption of Flex-Fuel Vehicles (FFVs) and the integration of Sustainable Aviation Fuel (SAF). Investors should track government policy updates on procurement prices for grains, as these directly determine the viability of production for ethanol manufacturers.
