Cost to the Fleet Business
All this wasted energy must be paid for, and sadly is being paid for by the fleet customer. Using an estimate of 17p per kWh, we estimate that over the six months of usage, idling has cost this small fleet of six approximately £85. This may not seem significant, but this works out at £28 per vehicle per year, which soon adds up across a larger fleet, or when the fleet is fully electric.
Over 1,000 miles, we estimate the cost of idling to be £4.43 per vehicle, but this depends on the type of driving you are doing. Idling costs will be a lot higher for urban driving, where there is a lot of stopping and starting, compared to a vehicle which spends much of its time on motorways and dual carriageways.
Looking at our worst-case scenario, one vehicle wasted 117kWh of energy over the 6 months, equivalent to almost £20 of energy wasted over 700 miles. This equates to £25 per 1,000 miles, or £40 per vehicle per year. If all drivers were performing this poorly, costs to the fleet customer would be astronomical.
