(IGL) has raised the rates of compressed natural gas (CNG) by 5% and piped natural gas (PNG) by 6.5%, the second hike this month.

The price of CNG, used for transport, has risen by Rs 2.28 per kg to Rs 49.76 per kg in Delhi. The rate of PNG, used for cooking, is up by Rs 2.10 to Rs 35.11 per standard cubic meter. Rates in satellite cities of Gurgaon and Noida too have risen by a similar quantum.

The price hike was made to ‘partially cover the hike in input gas cost’, IGL said in text messages to customers. The rate of domestic natural gas rose 62% at the beginning of the month. Domestic natural gas price is revised at the beginning of October and April each year using a formula based on prices in international hubs.
