PNG to households in Noida, Greater Noida and Ghaziabad would cost Rs 27.30 per scm for consumption of 36 scm in two months, up from existing Rs 26.20 per scm.
Beyond consumption of 36 scm in two months, the rate applicable in these cities would be Rs 48.75 per scm, IGL said in a statement.
"We are constrained to revise the retail price of CNG and PNG mainly due to increase in the overall input cost of natural gas being sourced by us. Since there has been no change in the domestic gas allocation to IGL and is expected to remain at existing level in the near future as well, the increase in gas consumption is being met through higher priced imported LNG," IGL said.
The price of CNG was last hiked on December 27, 2013 when it was raised by Rs 4.50 per kg.
Also, the price of cooking gas piped to kitchens (PNG) was also increased by Rs 5.15.
This was followed by a steep cut of Rs 14.90 per kg in CNG rates and Rs 5 per unit in PNG prices as government increased allocation of cheaper domestic gas to IGL.
