AWNTY: Better metrics of progress to deliver public EV infrastructure
Introduction
Cenex and Vauxhall have worked together to create a suite of better metrics to measure the delivery of public EV Infrastructure (EVI).
AWNTY25 examines what has changed in near home and journey charging over the last 12 months. All the data can be viewed and downloaded in the Data Dashboard, below.
The original research, methodology and recommendations were published in Are we nearly there yet? in September 2024 with an accompanying webinar.
Key conclusions
The best measures must 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. This means measuring progress by charging use case: Near Home, Journey and Destination.
Using a unique combination of Cenex and partner datasets, we have found:
Near home charging index: supply is a 1.5 years ahead of demand nationally and coverage is growing - significant regional disparities remain.
Journey charging index: Â supply is six years ahead of demand, but gaps remain on some major roads.
Destination charging ratio: nationally comprehensive data is still lacking but car park operators can apply a simple equation to determine what EVI they need for their situation.
The data may be downloaded for use but is subject to the NEVIS Terms and Conditions. Reference: Cenex NEVIS, 2025.
