Description CNG bus (4~8 times/day) e-bus(4~9 times/day) Remarks
Revenue 17,550,000 18,500,000 2 hrs per day’s charging time (5% more revenue for EV)
Driver labor/admin 8,500,000 8,500,000 Same labor, but better working environment
Fuel cost 3,900,000 825,000 Aprox 80% saving, even incl. electricity cost increase

Net income 3,000,000 8,256,000 Monthly KRW 5,256,000 more revenue vs CNG
❖ The above is an estimation calculated based on the actual data of OO bus company in Bucheon-si, Gyeonggi-do from Dec, 2019 to March, 2020.
❖ CNG bus driver needs to spend 2 hours per day to fuel CNG bus, and it causes KRW100,000 loss, driver labor KRW50,000 and no service loss KRW50,000
(one time service revenue).
☞ City bus service savings will be KRW4.5 tril. for Seoul, KRW2.1 tril. For Busan, KRW2.5 tril for Incheon, KRW0.91 tril. For Daegu for 10 years.
