A visionary master plan. Singapore launched its Master Plan 2040 to envision how might a transport system should be designed to support a healthier and cleaner country. The Plan opens up doors for transformation of the bus fleet to clean energy.

Singapore LTA launched its Master Plan 2040 in 2019 which envisions a ‘Transport for All’ future with enhanced WCR (Walk-Cycle-Ride) infrastructure and options. Besides, LTA will transform its transport system to support healthy and clean environment. It pledged to transform its entire bus fleet and taxi fleet to use clean energy.

The city committed to having a 100% cleaner energy public bus fleet by 2040, like electric or hybrid vehicles. At early 2020, among the total 5,800 bus fleet there are 60 electric buses (50 single decker and 10 double decker) deployed.

Factors for development
Public finance
The Singapore Government has allocated US$804 million (S$1.1Bn) in 2017 to fund the purchase of electric bus over the next 10 years. The publicly funded buses will be operated by private operators.

Infrastructure
The Government continues to invest on infrastructure. A Swiss firm, ABB, is building electric bus chargers in Singapore that can recharge public buses in under 10mins. ABB will also provide 150 kW overnight charging systems that accommodates “sequential” charging of up to two electric buses parked at a depot.

Optimization process
Vehicle technology optimization is expected for bus deployment under tropical climates in Singapore. Due to the size of the batteries, the e-bus carries about 10 per cent less than the capacity of regular diesel buses. Therefore, optimization over operation model is to be arranged with the operators.

Environmental Impact

In Singapore, diesel commercial vehicles and buses are key local emission sources of particulate matter (PM) and nitrogen oxides (NOx). When these electric buses are deployed, in additional to reduction in air pollution, the CO2 carbon emissions from buses will be reduced as well - by approximately 7,840 tons annually, which is equivalent to the annual CO2 carbon emissions of 1,700 passenger cars.

A pioneer on e-bus. China set out a new energy vehicle program at 2009 to invest on vehicle and infrastructure in 10+ pilot cities. Shenzhen's route to full 100% electric bus fleet yielded valuable insights. Now, the city operates the largest electric bus fleet in the world with more than 16,000 buses.
