Delivering gas, electricity and water all day every day takes a fleet of specialist vechiles that have to be able to deal with scheduled and emergency work. The van fleet will include adapted vehicles with on-board power, compressors and a full load of equipment. In these cicumstances monitoring fuel use can be difficult and identifying a poorly performing vehicle or driver impossible without the right data systems.
But there is a real cost to running power systems that use diesel on which the full road duty has been paid and that cost should be determined. It can run into tens of thousands of pounds and must be compared with the alternative of towed equippment or separate fuel sources and balanced against the need to train drivers to tow equipment.
