India on Wednesday signed the gas sale purchase agreement (GSPA) for the Turkmenistan-Afghanistan-Pakistan-India (Tapi) gas pipeline, which upon completion would diversify its gas basket. With domestic gas output stagnating, the $7.6-billion Tapi gas project provides a ray of hope.

In five years, the country would have access to imported natural gas, in addition to imported liquefied natural gas and domestic sources, including coal bed methane gas.
