On 24 October 2018, LTA the awarded a contract for the Procurement of Electric Buses (E-Buses) to 3 different tenderers, at a total sum of $50.64 million.
|1||20 single-deck electric buses
(BYD K9 / Depot slow charging)
|BYD (Singapore) Pte. Ltd.||S$17.246 million|
|2||20 single-deck electric buses
(Linkker LM312 / Pantograph fast charging)
|ST Engineering Land Systems||S$15.148 million|
|3||10 single-deck and 10 double-deck electric buses
(Yutong E12 and Yutong E12DD / Depot slow charging)
|Yutong-NARI Consortium||S$18.247 million|
Initially, it was announced that the 60 electric buses will progressively arrive in Singapore from 2019, with the final batch delivered in 2020. Details regarding the depot and bus service allocation for the buses will be announced closer to the implementation date. These buses will hit the roads in early 2020.
In October 2020, amidst the launch of the Yutong E12DD electric bus, it was announced that the full rollout of electric buses would be delayed to 2021.
Under the scope of the tender, each successful tenderer will also provide charging infrastructure at both bus interchanges and bus depots. Furthermore, the LTA had opted to trial both cable charging and overhead pantograph charging methods. In contrast with the Hybrid Bus tender (awarded at $28.5 million), the 50 Volvo B5LH buses were procured at a significantly lower unit cost than each of the 60 electric buses (and their charging infrastructure).

Tender PT323 for Procurement of Electric Buses (E-Buses) was put up by the Land Transport Authority (LTA) on Tuesday, 12 December 2017.
As announced by Second Minister for Transport Ng Chee Meng during the Ministry of Transport’s Committee of Supply Debate in March 2017, the government intended to procure 50 hybrid buses and 60 electric buses in 2017. This allowed the LTA to expand its trial of such “green” vehicles, which while environmentally-friendly, were more costly and less suitable for the island’s tropical climate. Electric vehicles operating in Singapore consume a lot of energy for air-conditioning, and their batteries and/or hybrid systems work less efficiently in our warm and humid environment.
As for the Electric Buses, the Land Transport Authority would allocate the buses to all existing Bus Operators (SBS Transit, SMRT Buses, Tower Transit, Go-Ahead Singapore) for operation on selected bus services. As of 2018, the majority of LTA’s bus assets were Euro V compliant diesel buses.
A battery-powered all-electric bus had previously been trialled locally by a Public Transport Operator. Between November 2016 and May 2017, a BYD K9 bus was operating with Go-Ahead Singapore under an LTA-initiated trial. Previous trials in Singapore have involved diesel-hybrid buses such as the Sunlong SLK6121UF14H, and Zhongtong LCK6121G HEV, and Volvo B5RLE Hybrid.
Tender submissions closed on 23 April 2018 at 4:00PM after 2 extensions.
As of the tender closing time, 10 bids were submitted. As part of the tender evaluation process, the LTA took into consideration the track records of the firms, their technical capabilities, adherence to requirements and compliance with local regulations. Results were announced on 24 October 2018, with 3 different tenderers awarded the contract, at a total sum of $50.64 million.

Based on the tender award, LTA picked an alternate bid from ST Engineering that was $1.3 million higher than its quoted base price. Similarly, LTA had gone for an unknown option that increased the cost of the BYD tender by almost $800,000 (which was not reflected in the list of BYD’s alternate bids).
On 11 November 2019, one unit each of the Yutong E12 Bus (SG3098L), BYD K9 Bus (SG3060U) & ST Engineering Retrofitted Electric Bus were displayed at Ulu Pandan Bus Depot, alongside a graduation ceremony for bus technicians under the Certification for Technical Specialist (CTS) at the Bus Technical Specialist Certification Centre.
These buses would be deployed for revenue service in early 2020.

For the 60 electric buses, three firms were awarded the tender for 20 buses each, namely BYD, ST Engineering and Yutong-NARI Consortium. As part of tender requirements, tenderers were also required to provide the necessary charging infrastructure to support their fleets. ABB revealed in a press release on July 2019 that they would be supplying the electric bus charging infrastructure for BYD & ST Engineering as part of this tender.
The 20 BYD Electric Buses procured under this tender will be charged by 10 units of ABB’s 150 kW chargers at night at Seletar Bus Depot. For each charger, up to 2 electric buses can be connected and charged sequentially while parked at the depot, enabling all 20 buses to be fully charged within 4.5 hours.
For the 20 Linkker LM312 buses, ABB will supply 4 units of 450kW fast chargers at “key interchanges” based on the OppCharge interface. With an automated rooftop connection via a pantograph, these buses will take less than ten minutes to charge.
Chinese bus manufacturer Yutong, which won the tender under a consortium with Chinese electric power equipment supplier NARI, uses chargers supplied by NARI to charge their buses.
Chargers have been installed at Bulim Bus Depot & Loyang Bus Depot to support operations of these Electric Buses.
