How is Electricity Billed in Thailand?
Thailand has two main utilities: MEA (Metropolitan Electricity Authority) covering Bangkok and suburbs, and PEA (Provincial Electricity Authority) covering the rest of the country.
Progressive Rate Structure (Residential)
Bills use a tiered (progressive) rate — the more you use, the higher the rate per unit:
- First 15 units: 2.3488 THB/kWh
- Up to 100 units: 3.6237 THB/kWh
- Over 400 units: 4.4217 THB/kWh
Plus a 38.22 THB monthly service charge and 7% VAT.
