Surging prices threaten to spoil India's coming-of-age gas party

Surging prices threaten to spoil India's coming-of-age gas party

Rediff.com17 Dec 2021

Around 15 years ago, when Reliance Industries (RIL) struck natural gas in the Krishna-Godavari (KG) basin off the east coast, the government made plans to supply that fuel cheaply to scores of generators that sprang up in India triggered by the discovery. Most of the plants, which account for 6 per cent of India's total generation capacity, operate sparsely after the KG-D6 area first failed to meet production targets, and then finally shut shop. Affordable domestic gas was why those thermal plants came up and the rate of the fuel today is why those generators hardly operate. Record liquefied natural gas (LNG) rates may yet again unravel India's ambitions to expand use of gas in industries, households and vehicles. Rates, while volatile, may stay strong this decade as developed nations with higher purchasing power embrace gas as the transition fuel.
