The development of a reliable and accessible charging infrastructure network is essential for the successful roll-out of electric vehicles (EVs) on UK roads. In recent years, public perception has been that EV charge points in the UK are sparsely located and charging times are too slow to make long distance travel viable in an electric vehicle. As a result, both the uptake of electric vehicles and investment into the market have been impacted, leading to black spots in charging provision.
As part of our largest EV infrastructure project to date, Arup managed the delivery of rapid charge points to help Highways England create an ultra-low emission network. The network delivers against the Department for Transport's commitment in its ‘Road Investment Strategy 2015-2020’, ensuring a minimum of 95% of the Strategic Road Network (SRN), which comprises motorways and major A roads, has a rapid charge point every 20 miles.
Arup’s expert team helped to facilitate the implementation of electric vehicle charging points to ensure a more sustainable future in transport.
EV charging criteria
Arup worked closely with Highways England to develop and define essential criteria that newly proposed EV charge point sites must meet, including the ability to reach full charge in 30 minutes, accessibility within a five-minute drive of the SRN and to be available 24/7 to the public. This provided a project framework that ensures the following decisions enable a full network coverage that is always open, secure and accessible for users.
Gaps in the network
Many locations throughout the SRN are challenging and remote. The difficulty in identifying and securing financially viable sites, with adequate electrical power provisions, has created gaps across the network. Using GIS mapping techniques, we have undertaken a route analysis to identify existing charge point locations within a 2.5-mile driving distance of major road networks. This meant we could accurately calculate the coverage provided by these points, how many extra charge points were required and where to locate them.
Procurement model development
Arup developed a bespoke contract to facilitate an open competition. This resulted in two suppliers, Swarco and BPChargemaster, being awarded contracts to install, maintain and operate charge points for a minimum of seven years. The collaboration of our dedicated and responsive team has led to the installation and commissioning of 66 rapid charge points, resulting in a 20% network coverage increase. Surpassing DfT’s original aim, 97.4% of the SRN will now be within 20 miles of a rapid charge point. The provision of these additional rapid EV charging facilities will help alleviate concerns over electric vehicle range restrictions and thus encourage the wider use of EVs for long journeys.
EV Charge points’ usage
Highways England has been provided with access to the EV charge point operator’s online dashboards to monitor the usage of the charge points. This will allow environmental statistics to be measured and quantified across all charge point sites, including CO2 savings, equivalent trees saved and power consumption.
Decarbonising transport
Increased EV usage will not only limit emissions and reduce the carbon and noise footprints of Highways England’s network, but will also improve air quality and lead to improved health benefits for the wider community. Carbon savings will be monitored for a minimum of seven years by Highways England, helping to move the UK towards its commitment to achieving an 80% reduction in greenhouse gas emissions by 2050.
