BANGKOK, Thailand – Thailand will introduce a new residential electricity tariff from the September 2026 billing cycle, with households using less electricity set to pay lower rates under a new progressive pricing structure. Government spokeswoman Rachada Dhanadirek said the new structure is designed to reduce the cost of living by addressing electricity costs and the tariff system, with priority given to households with lower consumption. Under the new residential structure, the first 200 units of electricity will cost no more than 3.00 baht per unit. Units 201 to 400 will be charged at 4.1584 baht per unit, while consumption from unit 401 onwards will be charged at 4.3583 baht per unit.
The rates are applied progressively, meaning consumers pay the applicable rate only for electricity used within each tier rather than having their entire consumption charged at the highest rate.
The new structure also reduces the average electricity tariff for all customer categories, including the Ft charge, from 3.95 baht to 3.86 baht per unit, a reduction of 9 satang per unit.
In addition, the cost of public electricity services will be removed from residential electricity bills at a rate of 0.0634 baht per unit for consumption from 201 units upwards. This change reduces the energy charge for units 201 to 400 from 4.2218 baht to 4.1584 baht and for units above 400 from 4.4217 baht to 4.3583 baht.
The government estimates that more than 21 million households will benefit from the new structure, with total savings expected to reach about 18 billion baht. Another major change is an expansion of eligibility for residential electricity rates. People who genuinely live at a property but do not have permanent household registration may qualify if the electricity is being used continuously for residential purposes and they have a record of paying electricity bills for at least six months.
The new rules are intended to ensure that people who use less electricity receive the greatest benefit while extending access to households that may not have permanent registration at their place of residence. The Electricity Regulatory Commission has already notified the relevant electricity authorities of the new structure, which will be applied from September 2026 bills.
The government said the changes are intended to provide a more equitable electricity pricing structure while producing a tangible reduction in household costs.
