The Energy Policy Administration Committee has decided to gradually increase the price of natural gas for public transport by a total of three baht per kilogramme over 12 months.
Energy Minister Siri Jirapongphan said on Monday the committee would increase the price by one baht per kg every four months -- on May 16 and Sept 16 this year and Jan 16 next year.
The price of the fuel used by buses and taxis has been subsidised to keep it at 10.67 baht per kg, compared to the normal price at 16.01 baht.
State-owned oil conglomerate PTT Plc, as the sole distributor of the fuel, was ordered to subsidise the price.
Mr Siri added the price hike was not related to the fare hike of public buses starting on Monday.
