The production line sees between 10 and 14
buses a month roll out depending on spec-
ification and finishing. All of its production
bays are fully accounted for until the end of
the year which means any disruptions will be
far-reaching in terms of cost.
The genset installed in February 2015
at Busco’s production facility produces
280 kVa which, as Van Zyl points out, is
probably larger than what is required, but
he much prefers a unit that performs well
within its capability than one operating
under stress – which severely affects fuel
consumption. The entire facility can be run
off the genset when required including the
production line’s biggest power user – the
welding section.
Van Zyl chose not to electronically automate
the switch from supplied power to genset
power and rather switch the sources man-
ually as this allows for better fuel economy
as the unit then only runs when it is required
and not every time the power cuts – for in-
stance during the night or on a Sunday.
“Our genset currently runs for anywhere be-
tween six and eight hours a week but we
have also required it to run for periods of
eight hours straight on the odd occasion.
My initial predicative calculations indicated
that it would achieve an efficiency of around
22 litres per hour and I’ve been pleasantly
surprised that we are actually achieving a
much lower figure of 16 litres per hour,” ex-
plains Van Zyl.

A Scania bus rolls off the assembly line.
Scania gensets are available in two
variations to suit installations.
Prime power:
For continuous operation and
unlimited yearly operation time at varying
load. A 10 % overload power can be supplied
for one hour in a twelve hour period. These
units are available for fuel optimised and EU
Stage IIIA compliant gensets.
Standby power:
This rating is for the supply
of continuous electrical power (at variable
load) in the event of a reliable utility power
failure. No overload on these units is
permitted. These units are available for fuel
optimised gensets.
