Chakree Buranakanon, senior executive vice-president of PTT Group, said on Tuesday that gas production from Block A18 of the Malaysia-Thailand Joint Development Area (JDA) resumed as its closure for maintenance finished earlier than scheduled.
It had been scheduled for maintenance from June 13 to July 10, which raised concerns about electricity security in the South.
Mr Chakree said the JDA started to again supply gas to the Chana power plant at 3.35am on Tuesday. The pipeline in front of the plant was reopened at 4.35am and electricity generation resumed at 5am.
During the disruption, natural gas supplies in Thailand dropped by 420 million cubic feet a day. During the first 10 days of the disruption (June 13 to 22), natural gas for vehicles was in short supply in the South. Later PTT increased supplies to the region from elsewhere and was able to serve local demand from June 25 onwards, Mr Chakree said.
There were no blackouts in the South during the gas supply disruption, because domestic consumers and business operators agreed to cut power use during normal peak hours, Egat said.
