Electric Bus Trial in DTC The Delhi Transport Corporation (DTC) conducted an electric bus trial from March to June 2016. An electric bus was provided by BYD Auto Industry of China through their local partner. The key benefits of the electric bus included zero emissions, lower operating costs of Rs. 12.06/km compared to diesel, and a driving range of over 250km per charge. Over the trial period the electric bus covered nearly 13,000km with an expenditure of Rs. 17.10 per km. The electric bus requires less maintenance than CNG or diesel buses. DTC is considering expanding the electric bus trial and fleet given the successful results.
