State-run power PSU NTPC on Saturday moved the Supreme Court challenging the Bombay High Court judgement that allowed it to amend its petition on the gas dispute.
A ministerial group had approved USD 4.2 per mmBtu as the value of gas from RIL's KG-D6 fields, but before that the company had won a contract to supply 12 million cubic metres of gas per day to NTPC's Kawas and Gandhar projects with a bid of USD 2.34 per mmBtu in 2004.
The government has separately filed a petition in the Ambani brothers' gas dispute, saying it alone had the right to approve gas price.
