Cane out, grain in
Cane meets a closed gate in the 11 billion litre ethanol tender from India’s state-run fuel companies Indian Oil, Bharat Petroleum and Hindustan Petroleum. For the supply year beginning in November, ethanol made from cane juice, sugar syrup and B-heavy molasses is excluded. Ethanol from corn, broken rice and surplus rice supplied by the state grain agency Food Corporation of India remains eligible. The boundary changes which feedstocks can compete to supply the fuel. The physical question sits at the processing stage: does the cane become sugar for the market or ethanol for fuel?[1]
Concern about sugar output after poor rainfall in the Indian states of Maharashtra and Karnataka lies behind the choice. The government is trying to retain sugar for domestic consumption and lower high prices. Closing one route into ethanol restricts a competing use of the crop. The quantity of cane leaving the field, however, still depends on the harvest. The risk of weather-related production losses and diversion of existing cane into ethanol affect sugar availability at different stages. The tender acts on the allocation stage; it announces no additional crop to offset potential losses in the field.[1]
The grain procurement calculation
On the fuel side, the requested quantity is 11 billion litres. That is the scale of the invitation to bid, rather than delivered ethanol. The grain route also comes with a lower procurement price. The incentive for corn ethanol falls from 5.79 to 2.79 rupees per litre, taking its purchase price from 71.86 to 68.86 rupees. Excluding cane-based supplies creates room in the tender for grain processors, while the lower purchase price reduces revenue per litre. Both terms matter together: which feedstock qualifies and how much the resulting fuel earns.[1]
How attractive that shift is for producers depends on corn and rice acquisition costs and their conversion yield into ethanol. Abundant, inexpensive grain could cushion the lower ethanol purchase price; a tender requesting fuel supplies does not itself provide those inputs. The interests of sugar consumers and fuel buyers diverge here. One seeks the benefit of keeping cane in sugar production; the other needs ethanol made economically from eligible grain. The immediate change is at the feedstock gate. Accepted bids and completed deliveries measure how much usable supply comes through it.[1]
