The rate is calculated by taking a weighted average price at Henry Hub of the US, National Balancing Point of the UK, rates in Alberta (Canada) and Russia with a lag of one quarter. So for April 1 to September 30, period, the average rates prevailing during January 1, 2018, to December 1, 2018, would be taken. Sources said, the rates for 2018 are known and based on it the rise from April 1 comes to 10 per cent.

The increase in price will boost earnings of producers like Oil and Natural Gas Corp (ONGC) and Reliance Industries but will also lead to a rise in price of CNG, which uses natural gas as input. It would also lead to higher cost of natural gas piped to households (PNG) for cooking purposes as well as of feedstock cost for manufacturing of fertilisers and petrochemicals. The hike will boost producers like ONGC.

Every dollar increase in gas price results in Rs 4,000 crore additional revenue for the PSU on an annual basis, sources said adding ONGC is the country’s biggest gas producer, accounting for two-thirds of the over 70 million standard cubic meters per day current output.

The USD 3.72 per mmBtu price will be the highest since October 2015 to March 2016. India imports half of its gas which costs more than double the domestic rate. Natural gas prices were last hiked on October 1, 2018, by 10 per cent when rates moved up to USD 3.36 per mmBtu from USD 3.06. The increase will translate into a higher cap price based on alternate fuels for undeveloped gas finds in difficult areas like deep sea, which are unviable to develop as per the existing pricing formula.

The price for such fields from April 1 would be about USD 9 per mmBtu for six month beginning April 1 as compared to USD 7.67 currently, sources said. All of its gas, as well as that of Oil India and private sector RIL’s KG-D6 block, are sold at the formula approved in October 2014. This formula, however, does not cover gas from fields like Panna/Mukta and Tapti in western offshore and Ravva in the Bay of Bengal.
