By Hemant Sharma Every morning, millions of vehicles start on Indian roads. Flights take off, factories open, ships move, tractors enter farms, and households depend on LPG, petrol, diesel, ATF, bitumen, lubricants, and petrochemical products in one form or another. Behind this huge movement stands India’s refinery network — a powerful industrial backbone that quietly turns crude oil into the fuels and materials that keep the economy moving.
India is now one of the world’s major refining hubs. As per PPAC’s installed refinery capacity data, India’s total refining capacity stands at about 258.1 MMTPA, with large public-sector, private-sector, and joint-venture refineries spread across Gujarat, Odisha, Haryana, Kerala, Maharashtra, Karnataka, Andhra Pradesh, Punjab, Tamil Nadu, Assam and other regions.
This 2026 list focuses on India’s major oil refineries based on capacity, strategic importance, product contribution, petrochemical integration, and national energy value.
