2015-04-07 Item 2 - Attachment 1 - Pre feasibility Study of Electric Bus Routes

An estimated repair and cost per kilometre of $0.37 has been applied to all model instances
of Sunbus diesel buses in fleet calculations. This figure is based on information provided by
TransLink. A cost figure of $0.10 per kilometre has been applied to electric buses based on
data provided by manufacturers. A driver cost per kilometre of $1.41 has been provided by
TransLink, this has been applied across all of the modelled fleet options. All costs have been
discounted (at 7%) for ease of comparison.
As with the financial model, upfront purchase costs and estimated maintenance and
servicing costs were calculated in the financial model based on data received from
manufacturers in response to the EOI. The results of the 10 year operational model NPC on
these data are tabulated in Table 14. Once again, the upfront purchase costs include
capitalised costs of necessary infrastructure installation for each electric bus (e.g. two
charging stations).
