Electric vans - does the £8000 grant make them a good buy?

The UK government has just announced grants of up to £8000 to support sales of electric vans.  Will the take-up on these be better than the take-up of electric cars?  Arguably yes.  Businesses tend to make decisions based solely on economic criteria, and the economics support the purchase of an electric van under the right circumstances.  However, the truth is that very few firms would currently benefit from buying an electric van.  This is because of current technical constraints – they won’t last forever, but they will dent the growth prospects of EV vans in the short term.

Range: who will be able to use an EV van?

The first question everyone asks about electric vehicles is range.  Take for example the Renault Kangoo ZE, with a range of 106 miles.  Assuming no power infrastructure, that gives a return range of 53 miles, the distance from Bristol to the M50 junction with the M5.  At the moment, the UK network of EV charging points is underdeveloped, although Ecotricity is working on this.  The Ecotricity charge points are currently slow (6-8 hours for a full charge on a Renault Kangoo van), making their use for commercial transport impractical.

This means that at present, electric vans are only suitable for businesses that mainly serve their local area, or which have a fleet of more than one van, where at least one (electric van) could be dedicated to local service.

The typical charging time means these vans are also mainly going to be used only by firms that need the van intermittently, rather than driving all day.  For all day driving one would need either several vans, or a fast charge point, and while the prices of these are coming down they are still prohibitively expensive.

Running cost: who will gain financially?

Even at today’s high electricity price levels, running an EV is cheap compared to either diesel or petrol – about one fifth the cost.  On the other hand, the van itself is more expensive.  How many miles would you need to do to make the EV worthwhile?

This depends on your firm’s economic circumstances, of course, because the cost needs to be paid up front, while the savings will come over a number of years.  Let’s compare two firms – one drives about 115 miles per week, or 6000 miles per year, using the van for only about ¾ of an hour each weekday.  The other firm does 15K miles per year, or about 288 miles per week, using the van for nearly 2 hours per day on average.

First, the lower-mileage firm:

	Kangoo EV	Kangoo diesel	Difference
Price after subsidy	13,592	8,950	-4,642
Miles per gallon		54
KwH / mile	0.21
Battery lease £/month	60
cost per mile	0.02	0.11
miles per year	6,000	6,000
Road tax		115
Running cost per year	844	788	-56

In other words, for the low mileage firm it’s actually more expensive to run the electric van, even before we look at the up front cost.

Now let’s look at the higher mileage firm:

	Kangoo EV	Kangoo diesel	Difference
Price after subsidy	13,592	8,950	-4,642
Miles per gallon		54
KwH / mile	0.21
Battery lease £/month	105
cost per mile	0.02	0.11
miles per year	15,000	15,000
Road tax	-	115
Running cost per year	1,570	1,798	228

Unlike the other firm, this one gets an annual saving from driving the electric van, but the payback time is only about 20 years.  This means that even for the high mileage firm, which generates the most savings from driving, the electric van is still not currently worthwhile.

So will anyone benefit from buying an electric van?

There are some additional considerations on the financial side.  First, a central London-based firm will save on the congestion charge, which could mean that the choice to go electric pays for itself in a couple of years.  A firm with just one van delivering every weekday for 50 weeks of the year would save £2600.  Combined with the good EV charging network in London, this makes EV vans an excellent choice for firms that deliver within the London congestion charge zone.

Another consideration is the capital allowance – firms can claim 100% of the van’s cost in the first year.  Of course, SMEs with low capital spend may be able to do this anyway.  Whether this benefits your firm depends entirely on your circumstances.

Last but not least is the marketing benefit of driving a green vehicle.  Whether your customers are private sector bodies, socially conscious urbanites, or commercial firms looking to green their supply chain, driving an electric van can send out a useful marketing message.  It is difficult to quantify this but plenty of firms will no doubt use this argument to tip an uncertain financial decision in favour of the electric van.

Does this mean electric vans will never dominate?

No.  Many of the drawbacks depend on things that will change.  Range will improve.  The differential between electricity and petrol / diesel prices may widen.  EV charging will get faster, cheaper, and more ubiquitous.  So the economics of electric vans will change, and they will undoubtedly change for the better.  Of course, by that time there may be hydrogen powered vans competing for our business buck, but that blog entry will have to wait until 2015.
