LCQ16: Electric buses

     Following is a question by the Hon Jeremy Tam and a written reply by the Secretary for the Environment, Mr Wong Kam-sing, in the Legislative Council today (December 12):

Question:

     In 2010, the then Chief Executive indicated in his Policy Address that “[t]he ultimate policy objective of the Government is to have zero emission buses running across the territory.” Nevertheless, as at early this year, among the 36 single-deck electric buses purchased by franchised bus companies (bus companies) with full subsidies by the Government, only 24 buses had been put into service. It has been reported that bus companies face quite a number of difficulties should they switch to use electric buses for the whole bus fleets, including that thousands of bus parking spaces have not been installed with electric bus charging facilities, the power supply facilities at parking spaces and in bus depots do not have the capacity to meet the power demand for simultaneous charging of a large number of electric buses, and there are a host of technical issues. In this connection, will the Government inform this Council:

(1) whether it knows in respect of each bus company, the respective current numbers of bus parking spaces located at (i) bus termini, (ii) bus depots and (iii) other places, and among them, the numbers of those provided with charging facilities as well as their detailed locations (set out in a table by name of bus company and location of the parking space);

(2) whether it knows the following details of each of the electric buses already put in service: (i) the bus model, (ii) the manufacturer and place of origin, (iii) the route number and the first and last stops of the bus route plied by the bus, (iv) the number of breakdowns in the past year, (v) the location of and site area occupied by its charging facilities, and (vi) the amperage for charging (set out by name of bus company in a table);

(3) whether it knows the time needed for fully charging the supercapacitor buses already put in service and their power storage capacities, as well as their maximum travel distance; the maximum number of supercapacitor buses that can be simultaneously charged under the existing power supply facility of each bus depot;

(4) of the performance indicators for those electric buses which are plying (i) routes with more uphill roads and (ii) routes with more level roads (set out in the table below);
 

Performance Indicator (i) (ii)
(a) Maximum travel distance (km)    
(b) Fuel economy (km/kWh)    
(c)  Effectiveness in reducing emission of various air pollutants    
(d) Fuel cost (dollar/km)    
(e) Number of breakdowns each year    
(f)  Downtime due to repairs and maintenance (day/year)    
(g) Maintenance cost (dollar/km)    
(h) Total operating cost (dollar/km)    
 
(5) whether it has assessed if it is technically feasible to have more bus routes switched to be plied by electric buses; if it has assessed and the outcome is in the affirmative, of the route numbers and details of such routes, and whether there are plans and timetables for switching to plying such routes by electric buses;

(6) whether, in the coming three years, it will provide assistance to bus companies for installing more electric bus charging facilities and upgrading such facilities; and

(7) whether it has reviewed the progress in achieving the objective of “hav[ing] zero emission buses running across the territory” and the effectiveness of the relevant measures; if so, of the outcome; if not, whether it will conduct a review expeditiously?

Reply:

President,

     Electric buses do not have exhaust emissions. Successful replacement of conventional diesel franchised buses with electric buses in Hong Kong can significantly improve our roadside air quality. In this connection, the Government provided $180 million to fully subsidise five franchised bus companies, including Kowloon Motor Bus Company (1933) Limited (KMB), Long Win Bus Company Limited (LWB), Citybus Limited (CTB), New World First Bus Services Limited (NWFB) and New Lantao Bus Company (1973) Limited (NLB), to acquire 36 single-deck electric buses (including 28 battery-electric buses and eight supercapacitor buses) for conducting a two-year trial to test out their operational performance, reliability as well as economic feasibility in local conditions.

     At present, 26 battery-electric buses and four supercapacitor buses have commenced operation. The remaining two battery-electric buses of NLB are under re-tendering process (Note 1), and are expected to commence operation by the end of 2019 at the earliest. Besides, the four KMB’s supercapacitor buses are expected to commence operation in the first and second quarters of 2019 respectively.

     Our reply to the question raised by the Hon Jeremy Tam is as follows:

(1) and (2) The current number of bus parking spaces located at bus termini and bus depots in various districts are as follows:
 
  Number of bus parking spaces located at bus termini Number of bus parking spaces located at bus depots (including the parking area for the use of franchised buses only)
Hong Kong Island About 510 About 660
Kowloon About 330 About 1 080
New Territories About 770 About 2 000
Sub-total About 1 610 About 3 740
Total About 5 350
  
     As regards the electric buses which have commenced or completed the trials, the following information is set out in Annex 1: (i) number, model, manufacturer and origin of buses; (ii) service route (the origins and destinations); (iii) day of commencement of trial; (iv) location of charging facilities; (v) number of charging facilities and its site area; (vi) information of electricity storage device and charging requirement; and (vii) monthly average number of on-road breakdowns and bus availability (per cent).

(3) The four supercapacitor buses in operation are belonged to KMB and the trial has not yet completed (Note 2). According to the preliminary trial results, supercapacitor buses can be fully charged in about 20 minutes and travel about 20 to 30 kilometres (km) after a full charge. Therefore, supercapacitor buses are more suitable for short routes and franchised bus companies are required to provide charging facilities at bus stops and/or termini so that supercapacitor buses can be timely charged. To facilitate the trial of supercapacitor buses on the circular route of 284, KMB installed two charging facilities at Sha Tin Central Bus Terminus and KMB Sha Tin Depot respectively to ensure that supercapacitor buses could provide smooth and reliable bus services. Each charging facility can provide charging for one supercapacitor bus at a time.

(4) In general, the electricity consumption of electric buses running on uphill roads is higher than that running on level roads. The trial routes mostly compose of uphill roads and level roads, and thus we are not able to evaluate separately their performance for uphill roads and level roads. Having said that, according to the completed trials’ result of five BYD battery-electric buses, the energy consumption of trial route with more uphill roads (i.e. Route No. 81) is about 16 per cent more than the trial route with more level roads (i.e. Route No. 78). As regards the maintenance fee, the electric buses and charging facilities of the trial are still within the warranty period and the suppliers are responsible for the maintenance. As such, data about the maintenance fee and the overall operational fee are not available. A summary of the trial findings up to May 31, 2018 is at Annex 2.

(5), (6) and (7) Currently, there are about 6 000 franchised buses in Hong Kong. About 95 per cent of which are double-deckers and the remaining are single-deckers. The feasibility of promoting the implementation of electric bus services throughout or in individual areas of Hong Kong depends very much on the maturity of electric bus technologies, their prices and suitability for use in Hong Kong. We have to test and prove that the relevant technology is suitable for the local environment and the actual modus operandi of the public transport sector before introduction of electric buses on a large scale.

     The technology of single-deck electric buses is already used in places outside Hong Kong, but the operation in Hong Kong is subject to further test to ascertain the suitability for use in Hong Kong. The technology of double-deck electric buses is still developing and there are very few models available in the international arena. Furthermore, their passenger carrying capacity and operational efficiency still fail to fulfil the local operational needs (including long daily service hours, high peak passenger loadings, the need to tackle hilly terrains as well as intense air-conditioning demand in hot and humid summer, etc.). We will keep in view the technological development of double-deck electric buses and trials in other places so as to introduce suitable models for trial in due course.

     As regards the single-deck battery-electric buses, the two-year trial of the first batch of five BYD battery-electric buses was completed in May 2018. The overall average daily driving range of the five buses during the trial was about 190 km. However, under high ambient temperature demanding high loading of air-conditioning system, the driving range reduced to about 150 km, which could not meet the normal daily requirement of most of the single-deck bus routes of 200 to 300 km. It is our initial view that the wider use of single-deck battery-electric buses in Hong Kong will hinge on the following two factors:

(i) whether the battery capacity of single-deck battery-electric bus could be substantially increased later enabling it to travel about 300 km a day after a full charge; and/or

(ii) whether there is adequate space and power capacity for installation of charging facilities at the termini or public transport interchanges for top-up charging of the single-deck battery-electric buses in daytime taking into account mode of charging in daytime and high operation frequency of buses in Hong Kong.

     As for single-deck supercapacitor buses, they can travel about 20 to 30 km only after a full charge and thus more suitable for short routes. Bus stops and/or bus termini would be required to provide charging facilities for timely re-charging of the supercapacitor buses. Whether the supercapacitor buses can be further promoted depends on the availability of suitable short routes of single-deck buses and public transport interchanges or bus termini, which the routes pass through, that can provide adequate space and power capacity for installation of top-up charging facilities.

     The Government will continue to monitor the trial of electric franchised buses and work with the franchised bus companies to investigate the charging solutions to suit local operational needs. If the trial results are satisfactory, the Government will promote wider use of single-deck electric buses by the franchised bus companies, taking into account affordability of the companies and passengers. We will also keep in view the technological development of double-deck electric buses and consider at a suitable juncture to carry out trials with the franchised bus companies in Hong Kong.

Note 1: NLB completed the tendering for procurement of two battery-electric buses earlier. As the supplier has subsequently withdrawn their offer, NLB has to re-tender the contract.

Note 2: Two buses commenced the trial in March 2017 and and another two in November 2018. read more

DoJ statement in relation to ICAC investigation

     The Independent Commission Against Corruption (ICAC) conducted a comprehensive investigation into allegations of corruption and misconduct in public office (MIPO) against former Chief Executive of the Hong Kong Special Administrative Region Mr Leung Chun-ying and member of the Legislative Council Mr Holden Chow Ho-ding. The allegations arose from (i) Mr Leung entering into an agreement with UGL Limited (UGL) and receiving payments thereunder during the time when he was the Chief Executive and (ii) suspected interference by Mr Leung and Mr Chow with the inquiry of the Select Committee to Inquire into the Matters about the Agreement between Mr Leung Chun-ying and the Australian firm UGL Limited (the Select Committee). 
      
     Having carefully considered the investigation reports and the relevant materials submitted by the ICAC, the Department of Justice (DoJ) has advised that there is insufficient evidence to institute prosecution against Mr Leung and Mr Chow.

Prosecution criteria

     According to the Prosecution Code, a prosecutor must consider two issues in deciding whether to prosecute. First, whether there is sufficient evidence to justify instituting or continuing proceedings. Second, if there is sufficient evidence, whether the public interest requires a prosecution to be pursued. A prosecution should not be instituted or continued unless the prosecutor is satisfied that there is legally sufficient evidence to support a prosecution: that is, evidence that is admissible and reliable and, together with any reasonable inference able to be drawn from it, likely to prove the offence. The test is whether the evidence demonstrates a reasonable prospect of conviction. In the present case, the decision not to prosecute is solely based upon insufficiency of evidence.

DoJ’s decision

     The available evidence reveals that in late 2011, Mr Leung, a director of DTZ Holdings (DTZ), in the negotiation of the takeover of DTZ by UGL, entered into an agreement with UGL for the receipt of £4 million on the basis of “non-compete non-poach”. Part of the sum was received when Mr Leung was the Chief Executive.
      
     The totality of the evidence is that as part of the arrangement of the takeover, DTZ had knowledge of Mr Leung entering into agreement with and accepting money from UGL for Mr Leung’s non-compete non-poach arrangements. Furthermore, Mr Leung’s acts in negotiating the takeover with UGL were congruent with the interests of DTZ which was at the relevant time in financial difficulties. The evidence fell short of establishing DTZ did not consent to Mr Leung accepting the monies or that the conduct fell within the mischief of an agent accepting advantage charge within section 9 of the Prevention of Bribery Ordinance, Cap 201. There is no reasonable prospect of conviction of a corruption charge against Mr Leung.
      
     As to the absence of declaration of such interests to the relevant authorities, since there is no conflict of interest on the part of Mr Leung, there was no legal requirement for him to make declaration of the amount that he was to receive under the agreement with UGL entered into before he became the Chief Executive. The absence of declaration hence did not constitute any MIPO offence.
      
     Regarding the submission of amendments to the major area of studies of the Select Committee by Mr Chow which originated from Mr Leung, the amendments would not affect the proper functioning of the Select Committee. There is insufficient evidence to prove that such misconduct was serious enough to establish the offence of MIPO. 

     For the sake of completeness, there is also insufficient evidence to substantiate other criminal offences against Mr Leung or Mr Chow.

     The DoJ’s decision not to institute prosecution against Mr Leung and Mr Chow has been made in accordance with the Prosecution Code and the applicable law.

     The decision taken has been explained so that the public are fully and properly informed about this case which has been the subject of public concern. read more

Operator and manager of unlicensed guesthouses fined

     Two women were fined $3,000 and $8,000 at the Kowloon City Magistrates’ Courts today (December 12) for contravening the Hotel and Guesthouse Accommodation Ordinance.
      
     The courts heard that in April and May this year, officers of the Office of the Licensing Authority (OLA), the Home Affairs Department, inspected two suspected unlicensed guesthouses on Fuk Wa Street in Sham Shui Po. During the inspections, the OLA officers posed as lodgers and successfully rented rooms in these guesthouses on a daily basis.
      
     According to the OLA’s records, these guesthouses did not possess licences under the Ordinance on the days of inspection. The women responsible for operating and managing the premises were charged with contravening section 5(1) of the Ordinance.
      
     A department spokesman stressed that operating or managing an unlicensed guesthouse is a criminal offence and will lead to a criminal record. Upon conviction, the offender is liable to a maximum fine of $200,000 and two years’ imprisonment.
           
     The spokesman appealed to anyone with information about suspected unlicensed guesthouses to report it to the OLA through the hotline (Tel: 2881 7498), by email (hadlaenq@had.gov.hk), by fax (2504 5805) using the report form downloaded from the OLA website (www.hadla.gov.hk), or through the mobile application “Hong Kong Licensed Hotels and Guesthouses”. read more
