The state-run company plans to increase capacity of its gas-based power plants at Kawas and Gandhar expansion projects.

'Various issues for signing of gas supply and purchase agreement with Reliance Industries have been resolved, except one for which NTPC intimated its position to RIL and the same was not acceptable to them,' the company said referring to the case which is pending at the Bombay High Court.

The company, however, declined to comment on a recent RIL allegation that it had signed the contract to sell gas at $2.34 per unit but it was NTPC that did not reciprocate.

'Entire facts of the case are before the Honourable Bombay High Court and the matter is subjudice. Hence, NTPC does not want to comment on this,' it said in the regulatory statement.
