Dr. Phoolphat Leesombatpaiboon, Secretary-General of the Energy Regulatory Commission (ERC) and spokesperson for the commission, revealed that in the 44/2568 meeting (986th meeting) on 26 November 2025, the ERC considered the proposal for electricity rate adjustment under the automatic tariff adjustment formula (Ft) for January to April 2026. The Electricity Generating Authority of Thailand (EGAT) initially proposed a rate of 3.94 baht per unit to allow a refund of 6,141 million baht to cover accumulated cost burdens (AF). However, during the public consultation, PTT Public Company Limited (PTT) revised its natural gas price outlook downward. Consequently, EGAT proposed lowering the electricity rate to 3.88 baht per unit to align with the government’s policy to reduce living costs for the public.
"The ERC, under the authority of Section 67 of the Energy Industry Act B.E. 2550 (2007), which requires licensees such as EGAT to submit tariff proposals for the ERC's approval, considered EGAT's revised proposal based on PTT's expected decrease in natural gas prices. The LNG price was adjusted from 12.5 to 11.6 US dollars per million BTU. As a result, the initially proposed electricity rate of 3.94 baht per unit was reduced to 3.88 baht per unit (excluding VAT). This means the Ft charge for the January to April 2026 period dropped from 15.72 satang to 9.72 satang per unit," Dr. Phoolphat explained.
Dr. Phoolphat added that the electricity rate review was conducted based on legal frameworks and academic principles while considering financial discipline. The decision relied on the latest fuel cost estimates from EGAT and PTT, as well as EGAT's proposal dated 25 November 2025 to reduce the AF burden. This approach aims to maintain a balance between system stability and security and the energy cost burden on the public. The ERC will continue to closely monitor fuel prices and EGAT's accumulated cost burdens.
