Cenex was commissioned by the Midlands Net Zero Hub (MNZH) to assist ten Local Authorities (LAs) in evaluating their current fleets and depot operations. This assessment is part of the preparation for depot electrification and transitioning to fully electric fleet operations by 2035.

The project established a comprehensive evidence base to help each authority understand the implications of adopting a fully electric fleet. This includes analysing electrical demand, determining charging infrastructure requirements, estimating capital and operational costs, and identifying potential emissions reductions.

Additionally, Cenex provided tailored recommendations and guidance for the next steps, ensuring that each LA had the necessary insights and tools to effectively plan a viable transition to zero emissions operations.

Decarbonising LA fleets presents complex challenges due to the diversity of vehicles, operations, and infrastructure readiness across different regions. The ten participating LAs operate a wide range of vehicles, including heavy goods vehicles, light commercial vehicles, refuse collection trucks, and street sweeping fleets. Each of these vehicle types has distinct duty cycles and charging requirements.

One major consideration is managing the increased electrical demand from large-scale depot charging. Engaging with Distribution Network Operators (DNOs) is essential to confirm grid capacity and to manage upgrade timelines effectively. Smart charging has been identified as an effective strategy; for instance, modelling in South Holland showed a reduction in peak demand from 1,196 kW to 797 kW.

Additional complexity arises from the operational diversity, such as vehicles parked off-site or at drivers’ homes, necessitating tailored charging strategies. The LAs also differ in their stages of transition to electric fleets, calling for a flexible, data-driven approach to fleet planning and infrastructure development.

A comprehensive fleet baseline analysis was conducted across all ten LAs to establish the emissions profile of each fleet and evaluate the operational suitability of battery electric vehicles (BEVs). This analysis determined the power requirements at each depot and laid the groundwork for infrastructure planning.

Through detailed assessments of the infrastructure, the most suitable charging technologies and power outputs for each location were identified. This helped the authorities visualise where upgrades or engagement with DNOs would be necessary.

Cenex also conducted financial and emissions modelling to compare the total cost of ownership (TCO) between existing internal combustion engine (ICE) vehicles and BEV replacements. This analysis quantified potential cost savings, capital requirements, and emission reductions, enabling informed and strategic decision-making.
