RIL has circulated to urea manufacturing fertiliser units a new Gas Sale and Purchase Agreement (GSPA) for supply of natural gas from its eastern offshore KG-D6 fields from April 1 upon expiry of current 5-year supply contract at month end.
In the new GSPA, RIL has proposed to charge government- fixed rate for natural gas on Gross Calorific Value (GCV) basis instead of current practice of billing USD 4.205 per million British thermal unit on Net Calorific Value (NCV) basis, sources privy to the development said according to the PTI report.
The heat produced from natural gas is measured in calorific value. The heat rate is measured in gross (GCV) or net (NCV) basis. One GCV equals to 0.9 NCV and so on a like to like basis billing urea plants the new price of USD 8.3 per mmBtu on GCV would mean an actual rate of USD 9.13 on NCV basis.
A senior official in the fertiliser ministry said his ministry has taken up the issue of changes made by RIL in the GSPA with the Oil Ministry.
"We expect the Cabinet decision to price natural gas based on Rangarajan Committee formula to be implemented in letter and spirit," he said.
The Rangarajan formula of pricing natural gas at an average of international hub rates and actual cost of importing LNG into India does not specify pricing the fuel on GCV or NCV basis.
Since gas in its liquid form (liquefied natural gas or LNG) is imported into India on GCV basis, RIL is using the same logic to price gas from April 1, sources said. Currently, most of the domestically produced gas is priced on NCV basis.
