For heavy users, the Piped Natural Gas (PNG) will cost Rs 40 per standard cubic metre, beyond 40 PSCM.
The hike comes into effect from June 19.
GGC, a subsidiary of state-owned Gujarat State Petroleum Corporation (GSPC), has raised CNG prices from Rs 60.15 per kg to Rs 62.15 per kg, while piped cooking gas prices go up from Rs 21.50 to Rs 25.50 (up to first 30 SCM) per standard cubic metre (PSCM), a company statement said.
"In spite of several representations made by the state (Gujarat) government and repeated requests by GSPC Gas Company Ltd, there has been no allocation of any cheaper domestic gas by the Central government," the official statement said.
