The plant requires 2.7-2.8 million standards cubic meters of gas and the company is getting half of that from local sources at $10 plus per million British thermal units (mmBtu) for its one unit, K.S Raju told Reuters at an industry event.

"Because of high gas prices our one unit is shut for last two to three months," he said.

He said the second unit will start operations if prices of imported liquefied natural gas (LNG) decline to $12-14 per mmBtu.
