El Niño Threatens India’s Ethanol Blending Target 2026: Impact on E20 Programme and Energy Security
Key points
Why in the News?
India's Ethanol Blending Programme is facing fresh challenges due to El Niño-related drought conditions and below-normal monsoon rainfall, which have affected the production of sugarcane and maize, two important raw materials used in ethanol manufacturing.
According to a Reuters report published on 4 November 2026, India's ethanol blending rate could decline from the 20% E20 milestone to approximately 15–17% during the 2026–27 ethanol supply year, as shortages and rising prices of agricultural feedstocks put pressure on ethanol producers.
The government has also reportedly restricted the procurement of ethanol produced from certain sugar-based feedstocks to protect domestic sugar availability.
Key Highlights:
Ethanol Blending Target: 20% (E20)
Projected Blending Rate: 15–17% in 2026–27
Major Climate Factor: El Niño-related drought
Affected Crops: Sugarcane and Maize
Major Concern: Food Security vs Energy Security
Ethanol Supply Year: November 2026–October 2027
Important: The 15–17% figure is an industry projection, not an officially revised government target.
What Is El Niño?
El Niño is a climate phenomenon characterised by the unusual warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean.
It is the warm phase of the El Niño–Southern Oscillation (ENSO).
El Niño can influence global weather patterns, including the Indian summer monsoon.
Important Features of El Niño
Particulars | Details |
|---|---|
Phenomenon | El Niño |
Ocean | Pacific Ocean |
Region | Central and Eastern Equatorial Pacific |
Climate System | El Niño–Southern Oscillation (ENSO) |
Main Characteristic | Unusual warming of ocean surface waters |
Possible Impact on India | Weaker monsoon rainfall and drought conditions |
Opposite Phase | La Niña |
El Niño is often associated with below-normal Indian monsoon rainfall, but this relationship is not universal. Other atmospheric and oceanic factors also influence the monsoon.
What Is Ethanol Blending?
Ethanol blending refers to mixing ethanol, a renewable biofuel, with petrol to reduce the consumption of fossil fuels.
Ethanol can be produced from agricultural raw materials such as sugarcane, maize and rice.
What Is E20 Fuel?
E20 means petrol containing 20% ethanol and 80% petrol by volume.
India's Ethanol Blended Petrol (EBP) Programme aims to reduce crude oil import dependence, support domestic biofuel production and lower certain vehicle emissions.
How Is El Niño Affecting India's Ethanol Blending Programme?
1. Reduced Monsoon Rainfall
According to Reuters, India's monsoon rainfall in 2026 was nearly 13% below normal due to severe El Niño-related conditions.
The rainfall shortage affected agricultural production, particularly sugarcane and maize.
2. Decline in Sugarcane Production
Sugarcane is an important raw material for ethanol production.
Drought conditions in major sugarcane-producing states, including Maharashtra and Karnataka, have affected crop availability.
Lower sugarcane production has increased concerns about domestic sugar supplies.
3. Rising Maize Prices
Maize is another major feedstock for ethanol production.
Due to reduced production and strong demand, maize prices have increased, raising production costs for ethanol manufacturers.
Maize is also used in poultry feed, livestock feed and food processing, creating competition between different industries.
4. Food Security Concerns
India uses agricultural products such as sugarcane, maize and rice to produce ethanol.
When agricultural production declines, diverting these crops towards fuel production can increase pressure on food availability and prices.
The government has therefore prioritised maintaining adequate sugar supplies.
Government Restricts Sugar-Based Ethanol Procurement
In October 2026, the government reportedly directed oil marketing companies to stop procuring ethanol produced from certain sugar-based feedstocks for the 2026–27 ethanol supply year.
The reported restrictions apply to:
Sugarcane juice
Sugar syrup
Sugar
B-heavy molasses
However, ethanol produced from C-heavy molasses remains permitted under the reported procurement framework.
The new ethanol supply year began on 1 November 2026.
The restriction aims to protect domestic sugar availability during a period of reduced agricultural output and rising prices.
India's Ethanol Blending Programme: Important Facts
Particulars | Details |
|---|---|
Programme | Ethanol Blended Petrol (EBP) Programme |
Target | 20% ethanol blending |
Fuel Type | Biofuel |
E20 Composition | 20% Ethanol + 80% Petrol |
Major Feedstocks | Sugarcane, Maize, Rice and Molasses |
Main Objective | Reduce petroleum import dependence |
Ethanol Supply Year | November–October |
Major Challenge in 2026 | El Niño-related drought and feedstock shortages |
Why Is Ethanol Blending Important for India?
1. Energy Security
India imports a substantial portion of its crude oil requirements.
Ethanol blending can reduce petrol consumption and lower dependence on imported petroleum.
2. Support for Farmers
Ethanol production creates additional demand for agricultural commodities such as sugarcane and maize.
This can provide alternative markets for farmers.
3. Environmental Benefits
Ethanol is a renewable fuel that can reduce certain lifecycle greenhouse gas emissions compared with conventional petrol, depending on the feedstock and production method.
4. Rural Industrial Development
Ethanol production supports distilleries, agricultural processing industries and associated rural employment.
Challenges Facing India's Ethanol Programme
Challenge | Explanation |
|---|---|
Climate Change and El Niño | Irregular rainfall affects crop production |
Feedstock Shortage | Lower sugarcane and maize availability |
Food vs Fuel Debate | Agricultural crops are needed for both food and biofuel |
Rising Production Costs | Higher feedstock prices affect distillery profitability |
Water Consumption | Sugarcane cultivation can require substantial irrigation |
Import Dependence | Lower ethanol blending could increase petroleum requirements |
Conclusion
El Niño-related drought conditions have created significant challenges for India's ethanol blending programme by reducing agricultural feedstock availability and increasing production costs.
Although India achieved its E20 blending milestone in 2025, industry experts expect the blending rate could decline during the 2026–27 supply year.
The situation highlights the importance of balancing energy security, food security, agricultural sustainability and climate resilience in India's biofuel policy.
