Thailand Cuts Electricity Rates to 3.89 Baht per Unit
Thailand's Energy Regulatory Commission cuts average household electricity rates to 3.89 baht per unit from September 2025, with the first 200 units capped at 3 baht for all residential customers.
Poolpat Leesombat, secretary-general of the Energy Regulatory Commission, announced the final rates and new tiered residential electricity pricing after public consultation. From September 2025, the average rate will be 3.89 baht per unit, down from 3.95 baht, following the removal of public lighting costs from household bills. The base rate will drop from 3.78 baht to 3.72 baht per unit; when combined with automatic fuel adjustment charges, the September rate reaches 3.89 baht per unit.
The new tiered system sets the first 200 units at no more than 3 baht per unit for all residential customers, including those in rented homes, dormitories, and apartments. Usage from 201 to 400 units and beyond 401 units retains existing rates. This policy aligns with the National Energy Policy Committee's directive to cap the first 200 units at 3 baht or less for all residential users.
Leesombat explained that separating public lighting costs reduces household electricity burden and establishes a dedicated rate. The Energy Regulatory Commission will revise energy fund regulations to collect money from new sources—data centers, direct power purchase agreements, reductions in renewable energy adders, and community solar projects—to subsidize public lighting costs and residential rates. The three state power authorities will implement the new rates.
