As India accelerated ethanol production to achieve its 20% ethanol-blending (E20) target, the government encouraged the expansion of distilleries, banks financed new manufacturing facilities, oil marketing companies entered into long-term procurement agreements, and investors committed thousands of crores to increase ethanol production capacity. This strategy enabled India to meet its E20 target five years ahead of the original 2030 deadline. However, this rapid expansion has created a new challenge—not related to vehicle performance, environmental concerns, food security, or fuel efficiency, but one arising from excess production capacity.
Although the government has mandated the nationwide sale of petrol blended with 20% ethanol, the industry is now witnessing a mismatch between production capacity and current demand. Industry associations have begun highlighting surplus manufacturing capacity, prompting discussions on exporting ethanol to international markets.
According to the All India Distillers' Association (AIDA), India currently has around 370 operational distilleries, with another 40 under development.
The country has installed ethanol production capacity of nearly 2,000 crore litres. Against the current demand under the Ethanol Blended Petrol (EBP) Programme and other industrial applications, the industry estimates a notional surplus capacity of approximately 700 crore litres, AIDA told India Today Digital.
India currently consumes about 1,200 crore litres of ethanol annually for petrol blending, according to a report by The Economic Times.
This raises an important question: Is India producing—or preparing to produce—more ethanol than it currently requires? If so, what happens to the excess capacity? Additionally, if distilleries operate below their designed capacity, can they generate enough revenue to recover their investments?
The answer is more nuanced than a simple surplus. India is not sitting on massive unsold ethanol inventories. Instead, it has rapidly built manufacturing capacity that now exceeds present-day demand. The real challenge is determining how this additional production capacity can be effectively utilised.
Increasing ethanol blending beyond E20 is not an immediate solution because higher ethanol blends require vehicles designed to run on them. Brazil, often cited as a successful example, spent several decades gradually implementing its flex-fuel vehicle programme before achieving widespread adoption.
The issue is particularly significant because large bank loans financed many of these ethanol projects. Even if production remains below capacity, loan repayments continue.
According to the Ministry of Petroleum and Natural Gas, reverting to E10 petrol would put at risk investments worth nearly ₹1 lakh crore made in ethanol production facilities and associated infrastructure, much of which has been financed by public sector banks.
These developments raise several important questions. What exactly is ethanol? Why did India aggressively promote ethanol blending? Has the country fully achieved its policy objectives? Why is excess capacity emerging? Is the challenge one of production or demand? Could higher ethanol blends become the next phase of policy? And what are the implications for consumers, farmers, and the ethanol industry?
Operational distilleries are spread across states including Telangana, Rajasthan, Chhattisgarh, Odisha, Uttarakhand, Assam, Jharkhand and West Bengal, although several northeastern states and Union Territories still do not have ethanol production facilities.
1. What is ethanol, and why is it blended with petrol?
Ethanol is an alcohol produced through the fermentation of agricultural feedstocks such as sugarcane molasses, maize, rice, wheat, damaged food grains and other biomass. After fermentation and distillation, it is refined into fuel-grade ethanol that meets quality standards before being blended with petrol.
India uses ethanol under the Ethanol Blended Petrol (EBP) Programme, under which petrol sold at fuel stations contains a specified proportion of ethanol by volume. The current national standard is E20, consisting of 20% ethanol and 80% petrol.
According to the government, every litre of domestically produced ethanol blended into petrol helps reduce dependence on imported crude oil while creating an additional market for agricultural produce.
2. When did India's ethanol programme begin?
India launched its ethanol blending programme in 2001 with pilot projects involving 5% ethanol blending in selected states. However, progress remained slow for several years because of limited production capacity, inconsistent feedstock availability and policy uncertainty.
Momentum increased over the past decade following successive policy reforms under the National Policy on Biofuels and expanded procurement by public sector Oil Marketing Companies (OMCs). India achieved 10% ethanol blending in June 2022.
The government later advanced its target of achieving 20% ethanol blending from 2030 to Ethanol Supply Year (ESY) 2025-26 and successfully reached that goal five years ahead of schedule.
The Ethanol Supply Year (ESY) runs from November to October of the following year.
Brazil was the first country to implement large-scale ethanol blending beginning in the 1970s.
3. Why has the government strongly promoted ethanol blending?
The government's objectives extend beyond promoting cleaner fuels.
India imports nearly 88.5% of its crude oil requirements, making energy security a major national priority. Replacing a portion of petrol consumption with domestically produced ethanol reduces dependence on volatile global crude oil markets.
According to a government factsheet released on July 5, the ethanol blending programme has generated foreign exchange savings of approximately ₹1.90 lakh crore since ESY 2014-15. It has also replaced around 310 lakh metric tonnes of crude oil imports, reduced nearly 930 lakh metric tonnes of carbon dioxide emissions and generated approximately ₹1.60 lakh crore in additional income for farmers.
The programme has become a significant source of revenue not only for sugarcane farmers but increasingly for grain producers as well.
4. How much has India's ethanol industry expanded?
The growth of India's ethanol industry has been remarkable.
Government data shows ethanol blending increased from less than 1.5% in 2013-14 to 20% in 2025-26. Procurement rose from around 38 crore litres in ESY 2013-14 to an estimated 1,200 crore litres in ESY 2025-26.
Production capacity has expanded even faster. Installed capacity increased from approximately 421 crore litres in 2014 to nearly 2,000 crore litres by 2026.
This expansion required substantial investments in new distilleries, expansion of existing facilities, storage infrastructure and transportation networks across the country.
5. Why are people talking about an "ethanol glut"?
Amid concerns regarding vehicle mileage, engine compatibility and the implementation of E20, industry observers have increasingly referred to an "ethanol glut."
India has built significantly more ethanol production capacity than current domestic demand requires, making it the world's third-largest ethanol producer after the United States and Brazil.
According to AIDA, India currently operates around 370 distilleries, with another 40 under construction.
Installed capacity stands at nearly 2,000 crore litres, while current demand under the EBP Programme and industrial consumption is considerably lower, resulting in an estimated surplus capacity of around 700 crore litres.
Rather than allowing production capacity to remain idle, the industry is exploring ethanol exports to countries such as Nepal, Bangladesh and Indonesia, where ethanol blending programmes are expanding but domestic production capacity remains limited.
According to AIDA Deputy Director General Bharti Balaji, exports could help utilise surplus production capacity until domestic demand increases.
6. Does India currently have excess ethanol lying unsold?
Not necessarily.
The concern is not about large unsold inventories but about underutilised production facilities.
Establishing an ethanol distillery requires significant capital investment. According to the Institute for Industrial Development, a commercially viable 30 KLPD ethanol plant typically costs ₹55-60 crore, while larger facilities may require investments ranging from ₹150 crore to ₹300 crore or more.
KLPD stands for kilolitres per day and represents a distillery's daily production capacity.
Such investments are financially viable only if facilities operate at sufficiently high production levels over many years. If demand grows more slowly than anticipated, plants may remain underutilised, affecting profitability and making it more difficult to service loans and recover investments.
7. Has ethanol demand reached a plateau?
While ethanol demand appears to have stabilised after achieving the E20 milestone, it is expected to increase in the coming years as more flex-fuel vehicles enter the market.
The Ministry of Petroleum and Natural Gas indicated in March 2025 that it is interested in exploring blending levels beyond E20, including E30.
Such a move could further reduce oil imports, conserve foreign exchange and lower emissions. However, it also raises concerns regarding food security, water consumption and land diversion, particularly for grain-based ethanol production.
Given that the EBP Programme remains India's largest consumer of ethanol, scientific studies would be required before introducing higher ethanol blends on a wider scale.
According to AIDA, the industry has now transitioned from a "capacity-building phase" to a "resilience-building phase."
8. What does the latest ethanol supply data indicate?
AIDA's latest data suggests that ethanol supplies remain strong.
As of June 2026, distilleries had supplied approximately 717 crore litres of ethanol during ESY 2025-26.
Contracts had been signed for a total supply of 1,048 crore litres by the end of the supply year, meaning nearly 68% of contracted volumes had already been delivered by June.
Grain-based ethanol accounted for approximately 480 crore litres, representing nearly two-thirds of total supplies, while sugarcane-based feedstocks contributed around 238 crore litres.
Maize remained the largest feedstock, contributing 258 crore litres, followed by broken rice supplied by the Food Corporation of India (177 crore litres), sugarcane juice (144 crore litres), B-heavy molasses (82 crore litres) and damaged food grains (45 crore litres).
9. How has grain-based ethanol changed India's ethanol sector, and does the India-US trade deal matter?
India's ethanol programme was originally built around sugar mills, where ethanol was produced as a by-product.
Today, grain-based ethanol has emerged as the dominant source, accounting for nearly two-thirds of total supplies.
According to AIDA, diversifying feedstocks has reduced dependence on a single crop while improving year-round availability. Multiple feedstocks also provide flexibility when one crop experiences poor yields.
However, weather-related disruptions remain a significant risk.
In 2023, erratic monsoon conditions and lower sugarcane and rice production prompted the government to restrict diversion of these crops for ethanol production. Similar climatic events, including El Niño, could again reduce crop availability.
Moreover, expanding ethanol production from sugarcane and food grains raises concerns because both are water-intensive crops.
Separately, under an interim trade framework signed earlier this year, India agreed to reduce or eliminate tariffs on several American agricultural products, including dried distillers' grains (DDGs), red sorghum for animal feed, soybean oil, fresh and processed fruits, tree nuts, wine and spirits.
The agreement also aims to address longstanding non-tariff barriers while progressing towards a broader Bilateral Trade Agreement.
10. Why didn't the government continue selling E10 alongside E20?
Government officials argue that maintaining multiple petrol grades across more than one lakh fuel stations would create significant logistical challenges.
It would require separate storage facilities, transportation systems and dispensing infrastructure nationwide.
Given the substantial investments already made in E20 production and distribution, policymakers believe maintaining a single national fuel standard is more practical.
The Ministry of Petroleum and Natural Gas has stated that returning to E10 would undermine nearly ₹1 lakh crore invested in ethanol plants, storage facilities and logistics infrastructure.
According to a ministry statement issued on July 10, public sector banks have financed approximately ₹1 lakh crore worth of investments in ethanol production and associated infrastructure over recent years to support India's blending targets.
Although the government celebrated the early achievement of the E20 target as a major milestone, critics have argued that the transition was implemented too quickly.
Many experts believe the rapid rollout left owners of older vehicles facing compatibility issues and reduced fuel efficiency.
A more gradual transition, allowing E10 and E20 to coexist while older vehicles were gradually replaced by flex-fuel-compatible models, may have eased the adjustment for both consumers and ethanol manufacturers.
On the positive side, India now possesses substantial ethanol production infrastructure capable of supporting future growth. However, the challenge ahead lies in ensuring that this capacity is effectively utilised. For ethanol producers, the key objective will be operating their facilities at economically viable levels, while the long-term success of the ethanol blending programme will ultimately depend on wider consumer adoption and sustained demand.
