New £9m project aims to discover the impact mass electric vehicle charging could have on our electricity infrastructure

An £9m trial that will monitor the impact of electric vehicle charging on the local electricity infrastructure got underway in Buckinghamshire this week.

The ‘My Electric Avenue’ project will examine 11 ‘clusters’ of Nissan Leaf drivers around the country over the next 18 months, and provide information about how best to manage the demand for electricity when a large number of EVs in the same street are plugged in to their charging points at the same time.

The scheme’s first ‘street of the future’ has been created in Marlow, Bucks, where nine neighbours have received their new Leafs. Each ‘cluster’ of drivers has to receive their electricity from the same substation, so must live close to one another. The motorists have leased their Leafs for £100 per month, and had the charging equipment installed for free.

Electricity demand reaches its peak between 5.30-6.30pm, when residents drive home from work, turn on lights, watch television and prepare food. There is currently a question mark over what additional effect the charging of many thousands of electric vehicles would have on the grid.

As part of the scheme, a new piece of technology called Esprit is fitted to each of the participants’ charging posts, as well as at the local substation. If the demand for electricity reaches a certain level, the new device can delay the vehicle charging until later at night when the call for electricity has subsided.

Project director David A Roberts said: “Transition to a low-carbon economy is going to bring some fairly big changes to the way we all use electricity and energy. In particular, as we begin to decarbonise transport, that is going to pose a challenge to the electricity networks, both nationally and locally.

“It’s that local point that we’re really interested in. What we’ve seen with the uptake of technology such as photovoltaic solar panels in people’s homes is ‘clustering’. This is a social occurrence where one person in a street has them installed, and the rest tend to follow.

“Our hypothesis is the same will happen with electric vehicles, which could pose a challenge because the local electricity network isn’t designed to deal with everyone in a street using their appliances at the same time.”

Participants' driving and charging habits will provide information about managing the local electricity network as sales of cars with ‘plug-in’ capability continue to rise. It is also the first trial that directly controls domestic EV charging to prevent underground cables, overhead lines and substations being overloaded.

With some of the nation’s electricity infrastructure first put in place in the 1930s, the project aims to prove a solution that would avoid the need to dig up the roads to install higher capacity electric cables.

The My Electric Avenue project was first announced a year ago, and has now fulfilled all the criteria set out by energy regulator Ofgem to receive full funding from the latter’s low carbon networks fund.

In addition to Marlow, the other residential ‘clusters’ are in Chineham, Chiswick, Lyndhurst, South Gosforth and Wylam, with two more based in South Shields. In addition there are two ‘workplace-based clusters’: Slough Borough Council and Your Homes Newcastle.

The electric Nissan Leaf has its work cut out competing with cheaper mainstream cars - but it does make a case for itself

The project is led by private company EA Technology together with Scottish and Southern Energy Power Distribution, and includes several other companies including Nissan, Fleetdrive Electric and Zero Carbon Futures.

Oil is getting more expensive

I like the sound of a V8 as much as the next person, but one doesn't have to be a tree-hugger to take a healthy interest in the development of electric cars. Fossil fuels, whether running out in near future or not, are becoming more and more costly to obtain.
The current breed of EV is too expensive for what they offers, other than the exception of BMW i3 and Tesla Model S which offer the performance, innovation and sophistication that justifies the hefty price tag in comparison with the conventionally fuelled cars.

Seems to be a £9m feasibility study into proving how we don't need to update the aging national grid. Instead of spending cash around the edges making the odd handful of people think we're making progress we actually need to splash a few hundred billion on new power stations.

Hmmm ...

Let's be honest ... The only way we are going to be able to generate the large amounts of electricity required to satisfy the potential 'electric car' market is to build more power stations ... And given that fossil fuels are being exhausted, these power stations will have to be nuclear ... I wonder how many 'tree huggers' who buy electric cars will like that scenario? ...

Leaving aside the fact

that fossil fuels are no-where near being exhausted it's clear that the fans of "zero emission" electric cars are going to finally have to face up to the fact that this is a mirage. At the present stage of development and, with an honourable exception for the Teslar which I'd love to try, no sentient human being would buy an electric car with or without the baffling £5000 gift that you and I and every other tax paying member of the UK give every time one of the manufacturers sells one of them. It may be time for even the greenest of Guardian readers to realise that if the electric car does take off it's going to need huge infrastructure investment to fuel them. I find the technology fascinating but, like bio-fuels increasing the price of food in some of the poorest parts of the world, the law of unexpected consequences will not be denied.
