North Yorkshire is England’s largest county by area, largely rural, with long distances between stations. Dynamon used ZERO to plan fleet electrification for North Yorkshire Police: which vehicles can switch, and what depot charging all 45 sites need.

Key findings
- 407 vehicles modelled from 470 registered, using the force’s telematics.
- 88% of modelled vehicles can complete at least 95% of journeys in a current EV.
- 281 vehicles complete 100% of recorded journeys on a current electric model.
- 45 sites need depot chargers, every location in the study.
- 115 chargers recommended, with a higher share of rapid DC units than most fleets.
“By combining Dynamon’s analysis with real operational fleet data and input from police subject matter experts, this project provides a robust evidence base for understanding the scale of police fleet electrification and the investment needed to deliver it.”

The challenge
North Yorkshire is England’s largest county by area. Much of it is rural, and stations sit a long way apart. Vehicles cover those distances in normal duty, so a charging plan has to work across a dispersed estate.
The force registered 470 vehicles for the study, across 45 locations. 407 had enough telematics to be modelled in ZERO. All 45 locations need depot chargers.
The approach
Dynamon imported the force’s telematics into ZERO. Each modelled vehicle’s real journeys were simulated against current electric vehicle models, to see what share of duty a current EV could complete.
ZERO then sized depot chargers for every site and worked out the power demand those chargers would place on the site supply. North Yorkshire Police received access to ZERO for further scenario planning.
The results
Of the 407 modelled vehicles, 281 can complete 100% of their journeys in a current EV. A further 76 can complete 95–99%. Together, 357 vehicles — 88% of the modelled fleet — are suitable to go electric at the next replacement while still covering at least 95% of recorded journeys.
The plan recommends 115 depot chargers. Long distances between stations are why the mix includes a higher share of rapid DC chargers (50, 100 and 150 kW) than most fleets.
- 68 chargers at 11 kW AC
- 37 chargers at 50 kW DC
- 6 chargers at 100 kW DC
- 4 chargers at 150 kW DC
Part of a national programme
This study is one of 12 fleet reports Dynamon produced for the Midlands Net Zero Hub and the Department for Energy Security and Net Zero, with the Home Office. About 7,500 vehicles were registered across 480 locations, and about 6,400 were modelled on 26.5 million miles of telematics. Of those modelled vehicles, 82% (about 5,300) can go electric at their next replacement while completing 95% or more of their journeys. The studies recommended 1,563 depot chargers in total.
Force-level plans fed the national assessment of all 48 UK police forces and agencies, which Midlands Net Zero Hub has published. It estimates around 18,300 charge points across more than 2,000 police sites, and about £1.4 billion of investment, with around 80% of the cost in grid connections and electrical upgrades.
Regional clustering studies for Nottinghamshire, South Yorkshire and West Yorkshire looked at police and fire services sharing electrical infrastructure, and at ambulance services in the Hub’s programme. Shared infrastructure could cut grid upgrade costs by around 20% at suitable co-located sites.
The study gives North Yorkshire Police a vehicle-by-vehicle view of what can switch, a charger plan for all 45 sites, and the site power demand that plan implies.
