Nottinghamshire Police joined a fleet electrification programme for the Midlands Net Zero Hub and the Department for Energy Security and Net Zero. Dynamon used ZERO to test the force's real journeys against current electric vehicles and to size depot charging at all 39 of its locations.

Key findings
- 558 vehicles modelled from 622 registered, on 12 months of telematics.
- 95% of the modelled fleet can complete at least 95% of journeys on a current EV, the highest share in the programme.
- 167 chargers recommended at all 39 locations: 126 at 11 kW, 39 at 50 kW and 2 at 100 kW.
- 7,324 kWh of charging energy a day at Sherwood Lodge, plus an extra 549 kW of grid capacity.
- 5.8 million miles of real journey data used to test current electric vehicles.
“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
Nottinghamshire Police registered 622 vehicles across 39 locations. Every one of those sites needs depot chargers if the fleet is to electrify while keeping operational cover. The force needed to know which vehicles can switch at replacement, how many chargers each site needs, and where the electricity supply will limit the plan.
Sherwood Lodge, the force headquarters, shows the scale of that constraint. Charging there would draw 7,324 kWh a day and need an extra 549 kW of grid capacity.
The approach
Dynamon imported 12 months of telematics into ZERO, covering 5.8 million miles. Of the 622 vehicles on the fleet list, 558 had enough data to simulate. ZERO ran each modelled vehicle's real journeys against current EV models, then sized depot chargers for every site and calculated the power each site would need.
Nottinghamshire was also one of three regional clustering studies. Police and fire sites were assessed together, alongside Nottinghamshire Fire & Rescue, to see where the two services could share electrical infrastructure.
The results
328 modelled vehicles complete 100% of their journeys on a current EV. A further 202 complete 95–99%. Together, 530 vehicles (95% of the modelled fleet) can go electric at the next replacement while completing at least 95% of their journeys. That is the highest share of any fleet in the programme.
All 39 locations need depot charging. ZERO recommended 167 chargers. At Sherwood Lodge the charging energy is 7,324 kWh a day, which needs an extra 549 kW of grid capacity.
- 126 chargers at 11 kW
- 39 chargers at 50 kW
- 2 chargers at 100 kW
Part of a national programme
This study is one of 12 emergency-service fleet reports Dynamon produced for the Midlands Net Zero Hub and the Department for Energy Security and Net Zero, with the Home Office.
Across those fleets, about 7,500 vehicles were registered at 480 locations, and about 6,400 were modelled on 26.5 million miles of real telematics. 82% of the modelled vehicles, about 5,300, can go electric at their next replacement while completing 95% or more of their journeys. The programme recommended 1,563 depot chargers in total.
Clustering studies in Nottinghamshire, South Yorkshire and West Yorkshire looked at police and fire sites together, and at ambulance sites in the Hub's programme. At suitable co-located sites, shared infrastructure could cut grid upgrade costs by around 20%.
Midlands Net Zero Hub has published the national assessment of all 48 UK police forces and agencies. It estimates around 18,300 charge points across more than 2,000 police sites, and an investment of about £1.4 billion. Around 80% of that cost is grid connections and electrical upgrades. Nottinghamshire Police received access to ZERO for further scenario planning.
Nottinghamshire Police now has a vehicle-level electrification plan from 5.8 million miles of real journeys, a charger layout for all 39 sites, and a clear grid requirement at Sherwood Lodge.
