Thailand sets new electricity rates to lower bills from September
Beginning with the September 2026 billing cycle, a progressive residential tariff will cap the first 200 units at THB3.00 per unit and broaden eligibility.
- New electricity rates will take effect from the September 2026 billing cycle to lower costs for consumers.
- A progressive rate structure will be introduced for residential use, charging less per unit for lower consumption levels.
- The average electricity tariff for all customers will be reduced from THB3.95 to THB3.86 per unit.
- Eligibility for the new rates will be extended to actual residents, even those without permanent household registration, who have a consistent payment history.
Government spokeswoman Rachada Dhanadirek said consumers would begin to benefit from a new electricity tariff structure from the September 2026 billing cycle.
The change forms part of a government policy to ease the cost of living by addressing underlying electricity costs and the tariff structure in a sustainable manner, with customers who use less electricity in particular set to pay lower rates.
Residential electricity will be billed on a progressive rate structure.
The first 200 units will cost no more than THB3.00 per unit, units 201–400 will cost THB4.1584 per unit, and usage from unit 401 onwards will be charged at THB4.3583 per unit.
The structure is intended to ensure that charges reflect actual consumption and give priority to households with lower usage.
At the same time, the average electricity tariff for all customer categories, including the Ft charge, will fall from THB3.95 to THB3.86 per unit, a reduction of 9 satang per unit.
The burden associated with public electricity charges will also be separated from consumers’ electricity bills, providing a further reduction of THB0.0634 per unit.
More than 21 million households are expected to benefit, with combined savings estimated at THB18 billion.
The government spokeswoman said another significant change was the extension of eligibility to actual residents even without permanent household registration.
Those who have used electricity continuously for residential purposes and have a payment record of at least six months will also qualify for the new tariff.
“The principle is clear: people who use less electricity should pay less, and actual residents must be able to access the entitlement. The government wants this reduction in electricity charges to have a tangible effect on people’s bills while making the tariff structure fair and sustainable over the long term,” Rachada said.
