He attributed the new record to the persistent heat, with average temperature of 38.3 degree Celcius across the country.
He noted that it is possible that Thailand would make new records this year, if the weather condition remains unchanged. More power consumption is expected from all segments particularly the business sector.
"Primarily, the power consumption increased due to air-conditioners," he said.
The new power peak was recorded at 2.13pm today, according to the Electricity Generating Authority of Thailand.
The previous peak was recorded on April 7, at 27.056.8MW.
