Thailand's energy regulator (EGAT oversight authority) has approved a significant rate reduction for households without permanent registration that were charged "temporary" electricity rates of 6.80 baht/unit. Starting September 2026, these ~40,000 households will pay the standard residential rate—capped at 3 baht/unit for the first 200 units—bringing parity with registered homes after charging inflated rates for over a decade. Consumers should verify their September bills for the correction; those with 6+ months payment history and residential-use meters qualify immediately.
