Regional charging infrastructure requirements.

Public EV charging networks have been the subject of much debate and scrutiny, particularly when it comes to charge point deployment in rural and less populated regions. Critics argue that networks often prioritise installation in cities and highly populated areas, leaving rural communities with limited access to charging infrastructure.

However, this argument fails to take into account the nuanced needs of individual regions when it comes to EV charging. Rather than relying on blanket assumptions, it is essential to assess factors such as the number of “on-street households” in a given region, typical mileage, and seasonal traffic. By taking these factors into account, public charging providers can ensure that their networks are designed to meet the needs of all drivers, regardless of their location.

One key factor that must be considered is the number of “on-street households” (households without off-street parking) in a region. For those without a driveway or garage for home charging, the need for on-street overnight slow charging provision and rapid chargers at destination locations is much greater. 

For example, while public chargers per 100 people may appear high in London, a closer look at the numbers reveals that some densely populated areas, such as Ealing, there are only 4.7 chargers per 1000 on-street households. In contrast, the South Lake District has 10.5 chargers per 1000 on-street households.

In both regions, there will be a greater need for public charging, but the number, type and speed of charge points should reflect the type of housing prevalent in the area. 

Another key consideration is typical mileage. Whilst those living in rural areas are more likely to have a home charger, they also drive about 40% more miles each year than those living in urban areas, according to the National Transport Survey. For high-mileage drivers in rural areas, hubs of ultra-rapid charge points on major routes can serve the need for re-fills on long journeys or quick top-ups closer to home.

Seasonal traffic is another important factor to consider. Regions with high through-drivers and seasonal visitors require strategically placed ultra-rapid charging hubs, both on major routes and at or near their desired destinations. 

Public charging providers are already taking steps to address these nuanced needs. For example, in 2022-23, Osprey will open five new rapid charging destinations in North Devon in partnership with the council, as well as a 16-charger ultra-rapid hub in South Devon. These initiatives are part of a wider effort to create a whole ecosystem of varying speeds, locations, and use cases for public EV charging, that will meet the needs of all drivers across the UK.

We need to move away from simplistic measurements of charging provision and instead take a nuanced approach that considers the unique needs of each region. By doing so, we will ensure that charging networks are fit for purpose for all drivers, regardless of their location, and help to accelerate the transition to a cleaner, greener transport system.

Creating the right places right now, for the future of the planet.
