A private operator took over the routes the debt-laden state bus company gave up. In April 2026 it held licences for 2,273 electric buses; 1,576 ran on a typical day.

Private operator Thai Smile Bus has run electric buses on Bangkok's reformed route network since 2022, taking over routes the debt-laden state operator BMTA gave up when the Department of Land Transport reissued 237 route licences in 2024. The buses carry passenger counters, driver monitoring and telematics that feed a real-time arrival app; fares are tapped in and out on the operator's own HOP card, which rail does not accept. In April 2026, 2,273 buses served 124 routes but only 1,576 ran daily. Supplier Energy Absolute, whose then-CEO was accused of fraud by Thailand's securities regulator in 2024, has since provisioned against unpaid bills.
📊 Impact
Thai Smile Bus reported 2,273 licensed electric buses on 124 Bangkok-area routes in April 2026, of which 1,576 ran on a typical day. The Asian Development Bank, financing 1,200 of the buses in 2023, described the operator's 123 routes as nearly half of Bangkok's public bus routes.
🎓 Lesson
Handing electrification to a private concessionaire moved faster than the state operator could, but it tied the city's flagship green fleet to one company's balance sheet, and to its supplier's.

Four cities electrified the bus. Four different people own it.
The vehicle is nearly the same everywhere. What differs is who signed for it, who carries the risk when a supplier fails, and who the city can hold to a timetable.
