The Land Transport Authority (LTA) has announced the procurement tender for the latest batch of 660 electric buses. This move is part of Singapore’s ongoing efforts to transition to a cleaner, greener public transport system.
The tender, Procurement of Electric Buses (Contract PT602), was officially published today, 14 March 2025, and is open for submissions from eligible suppliers. This is also the first tender called for electric double-deck buses to have the three-door, two-staircase design.
The 660 buses comprise 360 single-deck buses and 300 double-deck buses.
According to LTA in a Facebook Post, this batch of electric buses will replace diesel buses that are reaching the end of their statutory lifespan.
Key Requirements for Bidders
To ensure compatibility with Singapore’s transport network, 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)
The LTA will adopt a 2-envelope bidding system, requiring tenderers to submit separate documents for pricing and technical specifications via the Government Procurement GeBIZ portal.
Additional Features
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 jerky movement of buses during acceleration
Driving Singapore Towards a Greener Future
This latest procurement follows the previous tender of 420 single-deck buses under Contract PT601 (Procurement of single deck electric buses), which also focused on expanding Singapore’s electric bus fleet.
As part of the LTA’s push to electrify Singapore’s public bus fleet, half of all public buses will be electric by 2030. To meet this target, LTA will procure more than 2,000 electric buses within the next five years, including double-deck models.
Manufacturers have also came forward with new three-door, two-staircase double-decker buses designed for the Singapore market. Three units were showcased at the LTA-UITP Singapore International Transport Congress & Exhibition (SITCE) 2024, namely the BYD BC12A05, CRRC eD12, and Zhongtong LCK6126EVGS (N12D).
Singapore’s commitment to electrifying its public transport system aligns with the nation’s broader Green Plan 2030 objectives. The adoption of electric buses is expected to significantly reduce carbon emissions, noise pollution, and reliance on fossil fuels.
For more details on the tender submission and requirements, interested parties can visit the GeBIZ portal or refer to LTA’s official procurement guidelines. The tender originally closed on 22 May 2025, 4:00pm, but has since been extended to 26 June 2025, 4:00pm.
As of closing time, 21 tenderers submitted their bids.

660 also not all double deck,Yes I agree just purchased 120 bendies for airport and some feeder svc usage only.
Hopefully ADL with 12.5m 2 staircase three doors,Volvo BZL three axles and Zhongtong DD.
SD will be Scania,MAN and MB.
These 660 new double deck electric buses under PT602 are set to replace the Volvo B9TL WEG2 Batch 1 to Batch 4.
It says 660 total buses ordered, 360 being single decks and 300 being double decks actually. The Single decks are probably ordered in preparation of the Retirement of the Euro V Scanias which begins in 2026 right after the Euro IV Scanias and the OC500LES, i would assume the current BYD BC12 & Zhongtong N12 should be enough to replace all the Euro IV Scanias & the OCs? The Double Decks which have 300 are likely just for Batch 1 & Batch 2 B9TL WEG2s which will begin retirement in 2027. Batch 3 & 4 still have some time left before they will retire so these 300 will likely just be for Batch 1 & 2. Really Hope LTA goes for other brands and not BYD or Zhongtong Again. Also personally the single decks should be 2 doors, the 3rd door kinda useless for a sd and it reduces the amount of seating as well. 3 doors should only be for dds and bendies. Another thing that is quite annoying is the recent ev buses(Zhongtong & BYD) has too many backwards facing seats.
No no no extension to any of the lousy and terrible Scania K230ub. They need to all be off the roads ASAP! The vibration of the Wright B9TL is due to poor maintenance and that problem can be solved
Double Decks? That means to replace the Batch 1 and 2 Volvo B9TL WEG2. First Batch Lifespan expires in 2027 which is about 2 years time. Hoping LTA may consider getting some ev bendies, the MAN A24 arent getting younger and are about 10+ years now, something need to be done soon. At the very least get some for airport and feeder services. Three door DDs are ok at least better than Three Door SDs but question is if deploy these on services where people alight after a few stops and not wanting to go upstairs and crowd on the 1st floor, whats the point of the 3rd staircase and 3rd door? Better get some Bendies as well. Also hoping LTA goes for some other brands instead of Zhongtong or BYD, would be nice to have variety. Curious if the Demo BYD K9RC did pass its trial or not.
Electric bendies, please??????
2 out of 10 chance but again they can consider buy 35 units for Airport supplements and 70 units for feeder back up.
