Since inception in 1984, GAIL has been the undisputed leader in the marketing, transmission and distribution of Natural Gas in India. As India's leading Natural Gas Major, it has been instrumental in the development of the Natural Gas market in the country. 

Currently, GAIL sells around 65 % of Natural Gas sold in the country. Of this, 31.3% is to the power sector and 31.5% to the fertilizer sector. Currently, GAIL is supplying around 59 MMSCMD of Natural Gas from domestic sources to customers across India. These customers range from the smallest of companies to mega power and fertilizer plants. GAIL has adopted a Gas Management System to handle multiple sources of supply and delivery of gas in a co-mingled form and provide a seamless interface between shippers, customers, transporters and suppliers. We are present in 16 states, i.e., Gujarat, Rajasthan, Madhya Pradesh, Delhi, Haryana, Uttar Pradesh, Maharashtra, Tamil Nadu, Karnataka, Uttranchal, Goa, Punjab, Kerala, Andhra Pradesh, Assam, and Tripura. We are further extending our coverage to states of West Bengal, Jharkhand and Bihar through our upcoming pipelines.

We are also actively pursuing opportunities in inter-regional gas trade both in the form of Pipeline gas and LNG.
