GAIL, Petronet LNG and Royal Dutch Shell say the companies have stopped buying gas from them. Gas is instead being sold to refiners, gas retailers, petrochemical producers and steel producers. Spot LNG prices have gone up from $10 per million British thermal unit (mBtu) at the beginning of this year to $15 mBtu. GAIL, which markets gas for Petronet LNG, has raised spot LNG prices twice since March this year.
