New metrics to measure the delivery of public EV infrastructure

We have published a new report and data dashboard on how to improve the metrics used to measure the delivery of public EV infrastructure.

This effort, supported by Vauxhall, concludes that current metrics to measure progress on the delivery and deployment of EVI are blunt instruments which do not fulfil all four definitions of a good metric:

  • Relevant to the reality of stakeholders’ needs;

  • Actionable for decision-makers;

  • Scalable across areas; and

  • Measurable with available data.

Our key finding on how to improve the metrics we use to track the progress of EVI delivery is that they must be more relevant: This means measuring progress by the type of charging that users are looking for: near home, journey and destination.

Using a unique combination of Cenex and partner datasets, we have created and analysed these new and improved EVI metrics across the whole of Great Britain, and found:

  1. Near home charging index:  supply is a few months ahead of demand nationally, but distribution suffers from significant regional disparities.

  2. Journey charging index:  supply is three years ahead of demand, but gaps remain on some major roads.

  3. Destination charging ratio: Car park operators can apply a simple equation to determine what EVI they need for their situation.
