India’s economy is booming. To meet the country’s growing energy demand, India increasingly relies on natural gas. By 2025, natural gas is planned to make up a fifth of the country’s energy mix. To achieve this goal, the 1,386-kilometer-long "East-West Gas Pipeline" will be laid on the subcontinent. The pipeline is planned to transfer 30 billion cubic meters of gas from the gas fields off India’s east coast (Kakinada, Andhra Pradesh) to the refineries located in the west (Ahmedabad, Gujarat).
