Natural gas, a very highly consumed commodity in India, is at present supplied from two sources: domestic production and imported liquefied natural gas (LNG). Energy demand and supply projections indicate that by 2021-22, due to rising demand, India will also need to start sourcing natural gas from cross-border pipelines to fill the gap between demand and availability. In such a situation, India will have to examine its options carefully to minimise the cost of imports and consider appropriate sources of natural gas to keep the import bills under check.
