My Electric Avenue trial – which involved large numbers of people running Nissan Leafs – finds which almost a third of local electricity supplies could need upgrading to handle EVs


Almost one-third of Britain’s local electricity networks could need upgrading if electric vehicles reach the point of mass acceptance, according to the results of a project funded by energy regulator Ofgem.

The three-year project, named My Electric Avenue, carried out trials to discover the impact which charging large numbers of electric vehicles (EVs) might have on local electricity networks at peak times.

the item aimed to assess how rising sales of plug-in cars as well as the larger battery capacities of vehicles could impact the country’s infrastructure from the year 2030.

The project recruited clusters of neighbours around the country to drive Nissan Leaf electric cars for 18 months, with the aim of to mimicing a future scenario where many people in an area choose to use a pure electric vehicle or plug-in hybrid electric vehicle.

the item analysed the various kinds of low voltage networks from the UK as well as the results suggest which four types could experience issues if as well as when the uptake of EVs increases.

Susceptible networks are typically characterised by available capacity of less than 1.5 kW per customer. Based on 3.5kW (16 amp) charging, about 312,000 circuits – 32% of Britain’s total – will “require intervention” if the nation reaches a point where between 40% as well as 70% of motorists own EVs.

The intervention would certainly normally mean the replacement of underground cables from the public highway, although the My Electric Avenue project trialled a potentially lower-cost solution from the form of ‘Esprit’.

Esprit will be an piece of technology installed into the electricity network which can control the charging of EVs if the local grid reaches a certain level of demand, preventing underground cables, overhead lines as well as substations being potentially overloaded. Forecasts suggest which Esprit could save around £2.2bn of infrastructure reinforcement costs up to 2050.

My Electric Avenue was hosted by Scottish as well as Southern Energy Power Distribution as well as led by EA Technology as well as funded through Ofgem’s Low Carbon Networks Fund. Partners included Nissan as well as Ricardo, with the latter providing independent technical verification to the project.

Olivier Paturet, general manager of zero emission strategy for Nissan Europe said: “Not only has My Electric Avenue provided us which has a greater understanding of the impacts of electric vehicle charging on local grids, although the item has also given us a clear vision of what the streets of the future may look like.

“EV sales are increasing at a phenomenal rate from the UK as well as wider Europe as well as the item’s vital which automakers continue to work closely with the energy industry to progress the EV movement.”

Stewart Reid, head of asset management as well as innovation at Scottish as well as Southern Energy Power Distribution added: “The project has been invaluable in showing us what challenges we are likely to face from the near future as more as well as more customers adopt EVs. the item’s also demonstrated which there will be a solution which will be capable of helping us overcome these challenges before they affect our customers.

“With brand-new vehicles due to place even greater demands on our networks, we are conscious of the need for both ourselves as well as the automotive industry to share our learning, challenges as well as innovations with one another. We are excited at This kind of prospect, which will allow the decarbonisation of our respective industries to continue at pace.”

In recent years the uptake of alternatively fuelled vehicles has risen dramatically coming from a very low starting point. coming from the start of the year to the end of November, a total of 66,929 EVs, hybrids as well as plug-in hybrids have been registered according to the latest figures issued by the Society of Motor Manufacturers as well as Traders.
