660 new 3-door electric buses procured by LTA

On 15 December 2025, the Land Transport Authority (LTA) announced that 660 new electric buses would be procured, in contracts worth S$322.2 million. Awarded to four manufacturers, this is the largest order of electric buses to date in Singapore, and also the first large-scale purchase of electric double-deck buses.

According to LTA, the contracts also included an option to procure up to 50 more electric buses if needed.

The procurement tender, titled Procurement of Electric Buses (Reference no.: PT602, was published on 14 March 2025. The LTA lists a three-door layout and two wheelchair bays as necessary features for buses supplied under this tender, and double-deck buses must also include two staircases.

The procurement of these electric buses and chargers represents another step towards Singapore’s public transport electrification goals, which aim to have half of all public buses be electric by 2030.

Tender Background

This latest procurement follows the previous tender for 420 single-deck buses under Contract PT601 (Procurement of single deck electric buses), which also focused on expanding Singapore’s electric bus fleet.

The tender, titled Procurement of Electric Buses (Reference no.: PT602), was called on 14 March 2025. The tender closed on 26 June 2025, at 4:00 pm.

The LTA has set forth several critical criteria that potential suppliers must meet:

• Compliance with Road Traffic (Motor Vehicles, Construction and Use) Rules
• Right-hand drive electric buses
• A configuration with one entrance and two exits
• Low-floor bus interior
• Provision of two wheelchair bays
• Two staircases for double-deck bus options (Base Offer 2)

The fourth requirement for a low-floor bus interior was removed after the tender was closed. (see: LTA drops mandatory Full Low-Floor Requirement for 660 New Electric Buses | Land Transport Guru)

In August 2025, LTA mentioned that new bus purchases (starting from March 2025) will have technological & safety features that aid Bus Captains. These include:

• Anti-fatigue system
• 360-degree collision warning system with artificial intelligence
• Camera mirror system
• Improved torque management, which aims to reduce the jerky movement of buses during acceleration

Finally, these buses will also be equipped with new colour electronic display systems at the rear of each bus to give surrounding road users clear visual signals of the bus captain’s intentions, including turning, stopping, and moving off. These features were recommended by the Bus Safety Tripartite Taskforce.

Award Criteria

According to the LTA, tender submissions were evaluated based on a two-envelope process that considered both quality and price. The price envelopes were only opened after the quality evaluation was completed. This approach ensures that LTA awards contracts to tenderers with high-quality and value-for-money proposals. For electric bus tenders, criteria such as the tenderer’s experience, track record, technical specifications of the proposed bus and compliance with local regulations were factored into the quality evaluation. The total life cycle cost was also considered.

All electric bus tenderers awarded were established bus suppliers. The three winning tenderers for double-deck buses — ST Engineering Mobility Services (partnered with CRRC), BYD, Yutong and Cycle & Carriage Automotive (partnered with Zhongtong Bus) — all exhibited double-deck electric buses at the Singapore International Transport Congress & Exhibition (SITCE) 2024 trade show.
