India’s ethanol industry is facing a growing capacity surplus, with nearly 7 billion litres of production capacity currently without a guaranteed market. The country’s total installed ethanol production capacity has reached around 20 billion litres per year, while another 4 billion litres of capacity could be added during the current year, widening the gap between supply and demand.
India’s E20 ethanol blending programme requires around 11 billion litres of ethanol annually. In addition, the alcohol, pharmaceutical and chemical industries consume an estimated 3–3.5 billion litres. With overall demand significantly below available production capacity, ethanol plants across the country are currently operating at only around 60% utilisation.
Industry estimates indicate that capacity utilisation could remain in the 65–75% range over the next three years unless new demand sources emerge. Maharashtra is expected to account for one of the largest capacity surpluses, estimated at around 2.77 billion litres. The situation is putting pressure on ethanol producers to identify additional markets and applications for their output. 
Ethanol producers are increasingly exploring export opportunities and new domestic applications to absorb the surplus capacity. Potential export markets include countries that have established or expanding ethanol-blending programmes. Industry players are also examining new applications such as bio-isobutanol, which can potentially be used as a blending component in diesel.
The growing surplus has emerged as a key challenge for India's rapidly expanding ethanol sector. While the government has successfully increased ethanol blending in petrol under the E20 programme, a further mandatory increase to E25 or E30 is not currently planned. As a result, the industry is looking for alternative demand avenues to improve capacity utilisation and support investments already made in ethanol production.
The situation also highlights the need for greater diversification within the biofuel sector. Developing export markets, expanding industrial applications and commercialising new ethanol-derived products could provide additional outlets for producers. Without significant growth in demand, however, India's ethanol industry could continue to operate below its installed capacity over the coming years.
