Dhaka EV Bus Operator
Electric bus fleet operator for Dhaka city routes, using Chiang Mai's pilot as a template.

The ask
Launch an electric bus operating company for Dhaka urban routes, using Chiang Mai's proven EV bus model and Chinese bus hardware as the playbook, and positioning for a BRTC partnership or concession.
Why now
Chiang Mai's electric bus pilot — run on Chinese-assembled vehicles adapted for tropical conditions — has produced two years of operating data showing reliability, cost-competitiveness with diesel, and strong rider uptake. Bangladesh's government has committed to electrifying 30% of public transport by 2030 and is actively seeking private operators to deploy alongside BRTC. Chinese EV bus prices have fallen to $80,000–120,000 per vehicle, and Chinese OEM financing is increasingly available for South Asian operators.
Why Bangladesh
Dhaka has some of the worst urban air quality in Asia; diesel buses are a major contributor and the political will for electrification exists. BRTC operates a decaying diesel fleet with chronic maintenance costs — a private EV operator offering better reliability and lower emissions is commercially and politically attractive. The power grid in Dhaka metro is stable enough for depot charging; the Solar + grid dual-feed model used in Chiang Mai is directly replicable. Bangladesh's flat geography and shorter average route lengths suit the battery ranges of current mid-price Chinese EV buses.
As a business
Revenue from per-kilometre service contracts with BRTC or DNCC (Dhaka North City Corporation), or from direct fare collection on concession routes. The EV operating-cost advantage over diesel (fuel + maintenance ~40% lower) is the margin driver; the business case strengthens further if carbon credits are stacked on top. Fleet financing via DFI green bonds (ADB, IFC) and government viability-gap funding is the capital structure template used across South and Southeast Asia.
Economics
Move the sliders to model an EV bus operation. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

What ZEPH would back
A founder with a prior relationship inside BRTC, DNCC, or the Ministry of Road Transport — this business lives or dies on the government contract, and we need to see that relationship before capital goes in. Ideally a team that has already run a smaller fleet operation (CNGs, minibuses) and understands Dhaka's informal transport economy from the inside.
Impact
A 20-bus electric fleet operating 180 km/day each displaces roughly 390 tCO₂e/year compared to an equivalent diesel fleet (diesel at ~1.0 kg CO₂e/km vs grid EV at ~0.18 kg CO₂e/km on BPDB mix). Scaling to 200 buses — a single concession route — avoids ~3,900 tCO₂e/year while eliminating the NOₓ and particulate emissions that cost Dhaka an estimated 1–2% of GDP in health impacts annually. Per-kilometre operating cost savings of 30–40% versus diesel create a commercially durable business even without carbon credits. Bangladesh's flat delta terrain maximises battery range utilisation, making the economics more favourable than in hillier South Asian cities.
