Bangkok: The Energy Regulatory Commission (ERC) has adjusted the electricity price for the period from September to December 2025 to 3.94 baht per unit, which involves a reduction of the Fuel Adjustment Charge (Ft) by 4 satang per unit.
According to Thai News Agency, Dr. Poonpat Leesombatpaiboon, Secretary-General and spokesperson for the ERC, disclosed that during its 30/2025 (972nd meeting) held on July 30 and 31, 2025, the ERC reviewed a proposal to adjust electricity rates using the automatic tariff adjustment formula (Ft). This proposal, initially put forth by the Electricity Generating Authority of Thailand (EGAT), suggested a rate of 3.98 baht per unit, inclusive of a 7.072 billion baht refund for outstanding costs to EGAT. However, following public feedback, EGAT proposed a further reduction to 3.95 baht per unit, recommending the use of approximately 4.9 billion baht from excess benefits to alleviate its electricity rates and debt burden.
The ERC, adhering to Section 67 of the Energy Industry Act B.E. 2550 (2007), which mandates licensees like EGAT to propose tariffs for ERC consideration, took into account EGAT’s revised proposal. In line with the ERC’s framework for determining electricity tariffs B.E. 2564 (2021), the commission aims to reduce electricity tariffs for consumers to mitigate the impact of current crises. This is further supported by the budget allocation framework under Section 34 (1), ensuring funds are utilized for tariff stability in future regulatory cycles.
Dr. Poolpat highlighted that the ERC resolved to allocate approximately 2.64 billion baht, one-third of the excess benefit refunds amounting to 7.927 billion baht, towards the reduction of consumer electricity bills, effectively decreasing the rate from 3.98 to 3.94 baht per unit. Consequently, the Ft charge for the September-December 2025 period will drop from 19.72 satang per unit to 15.72 satang per unit. The remaining 5.287 billion baht from the excess benefits will be reserved to uphold tariff stability in the subsequent regulatory cycle.
Furthermore, Dr. Poolpat expressed concerns regarding the potential rise in global natural gas prices towards the year’s end due to heightened demand during the European winter and geopolitical tensions, possibly leading to increased electricity production costs. In response, the ERC encourages the public to adopt simple changes in electricity consumption: unplugging appliances after use, turning off lights, setting air conditioners to 26 degrees Celsius, using energy-efficient devices, and planting trees to reduce indoor temperatures.
