SAMPLE DIGITAL DASHBOARD: The data used to create this interactive digital dashboard is fictional, and any resemblance to an actual fleet transition is purely coincidental. This dynamic platform is a powerful tool designed to simplify the complex process of transitioning municipal fleets for city staff and stakeholders. It provides actionable insights into fleet composition, energy use, cost comparisons, and environmental impact, empowering city leaders to make data-driven decisions. By tracking key metrics such as vehicle purchases, retirements, grant opportunities, and regulatory changes, the dashboard serves as a living document that evolves alongside your fleet’s transition. Whether navigating budget considerations or exploring new EV models, this tool equips city staff with the clarity and resources needed to plan and manage a successful, sustainable fleet transformation.

Fleet Electrification Assessment

Charging Infrastructure Transition Planner EV Procurements ACF Compliance GHG Emission Reductions
By electrifying it’s fleet, the City will reduce greenhouse gas (GHG) emissions and criteria air pollutants which will benefit the local population. Economic benefits from fleet electrification include lower lifecycle costs for electric vehicles and reduced fuel cost and price volatility when compared to internal combustion engine (ICE) vehicles.
 
The City commissioned a consultant team to evaluate the short- and long-term cost savings associated with the transition to EVs, determine impacts and benefits to the City, and outline steps to efficiently and cost-effectively integrate EVs and charging infrastructure at municipal facilities. The purpose of this assessment was to evaluate the current municipal fleet composition and make recommendations for transitioning from ICE vehicles to EVs within 15 years to the extent feasible. Commitment to fleet electrification will help move the City closer to achieving its climate mitigation goals. 
 
This assessment was created using data provided by City staff as well as from information gathered during subsequent meetings and interviews. Our EV deployment recommendations are in alignment with the City’s strategies as described in the City’s climate action plan. Our recommendations address 2025-2028 procurement cycles in detail and 2029-2040 procurement cycles more generally to ensure fiscally responsible procurement and deployment of EVs as well as proposed charging infrastructure.

Analysis Overview

The team analyzed the impacts of transitioning the City’s fleet of 1,572 light-, medium-, and heavy-duty internal combustion engine (ICE) vehicles, located at 56 facilities, to electric vehicles (EVs). Off-road equipment and vehicles not subject to the Advanced Clean Fleets rule were excluded from this analysis. The team recommends the deployment of 388 (L2) electric vehicle supply equipment (EVSE), chargers, 21 DC (slow) chargers, and 32 DC Fast Chargers (DCFC). Two scenarios are presented:

• Baseline Scenario: Business as usual case where the City would continue using ICE vehicles

• Transition Scenario: Scenario where the City would purchase EVs and install EVSE (L2, DC (slow) and DCFC

Our analysis shows that transition of the City’s municipal fleet to electric vehicles would cost the City an additional $14.4 when compared to the Baseline scenario over a 15-year period, and save the city around $43.7M in operating expenses. This transition should also reduce GHG emissions by 122.8 MMtCO2e over the same period. The cost reductions in the transition scenario are driven by vehicle incentives, Low Carbon Fuel Standard (LCFS) credits, fuel cost savings and reduced maintenance costs.

EVSE Recommendations

The team recommends that the City install 32 dual-port 150 kW DCFC in addition to the 388 dual-port L2s, and 21 DC (slow) single-port chargers. This will provide 797 slots for charging vehicles using shared L2s and DC (slow) chargers. Sixty-four vehicles may be charged simultaneously at the DCFCs. We are assuming “take home” vehicles would be charged at home or at an available charger during operating hours. 

The installation of chargers will cost the City about $29.5M which will provide 97% more charging capacity than is needed to power the EV fleet. The EVSE utilization rate is calculated by dividing the total daily kWh demand by the daily EVSE charging capacity at peak charging rates. EVSE will only charge at peak rates when the vehicle’s onboard charger will allow it and when the battery is fully discharged, so this metric should be viewed as a rough estimate of unused charging capacity. 

The annual EVSE operating expenses include charger depreciation (assuming an 8-year lifetime of each installed charging station), maintenance (routine, preventative, corrective), software/licensing fees, and networking fees. Electricity costs are included in the EV operating costs.

Two vehicles may be charged simultaneously at the DCFCs. We expect new EV models will have reduced charging times in the near future. Charging an EV is already comparable to fueling a gasoline vehicle in some cases, so there should be no need for dedicated fleet personnel to charge and reposition EVs. 

The visualization below includes a map of the proposed EVSE installations along with their associated capital and operating costs (to be added later).

Transition Planner

Recognizing that there are many ways to achieve full fleet electrification, this Transition Planner (see visualization below) will allow the City to consider many different approaches to achieving this goal. For example, the City may prioritize the replacement of the oldest vehicles first, or it may decide to replace vehicles by facility, based on availability of EVSE. Use the Transition Planner  to explore ways to adjust costs and timelines to fit anticipated budgets. This planner uses representative vehicle capital costs and may not reflect the actual vehicle costs of the chosen make and model at the time of purchase.

EV Capital Costs by Department

It will cost the City about $112M to transition the current ICE fleet to EVs over the next 15 years. Many vehicles are past their useful lifespans, and are due for immediate replacement. To reduce the cost of EVs due to be replaced in 2025, some vehicles are assumed to have a deferred replacement. Police patrol vehicles are expected to complete one more lifecycle as a conventional or hybrid vehicle. Vehicles subject to the Advanced Clean Fleets rule have been deferred according to their group category. All vehicles should be transitioned by 2040. Costs for replacing electric vehicles are not included in this analysis.

Electric Vehicle Procurements

Many light-duty EVs in the market today could meet the City’s needs and are reasonably priced. However, it might take five or more years for Class 3–8 EVs to reach sticker price and range parity with their conventionally-fueled equivalents.

The City might also consider replacing some of its medium-duty vehicles with light-duty vehicles (e.g., Ford F-250 replaced with a Ford F-150 Lightning) where increased towing and hauling capacity is not needed. The Ford F-150 Lightning reportedly loses around 50% of its range when towing equipment, but this might still be acceptable performance for some of the City’s duty cycles.

For M/HD vehicles that haul or tow short distances, there are a number of EV options available now. Some vehicle types are better suited to electrification than others. For example, bucket trucks, yard tractors, buses and panel vans typically have duty cycles where an EV alternative is suitable. Other vehicle types are much more difficult to electrify, such as dump trucks, vacuum trucks and rodders, which require significant amounts of energy to operate. Battery electric refuse trucks and sweepers are available now, though their range and performance are still somewhat limited.

The City may also optimize the number of vehicles included in its fleet based on operational requirements. Employee surveys can collect data about needs, and we recommend a simple online survey or trip diary to record several days of travel. This could help to reduce overall capital and operating costs for vehicles and chargers if some existing low-use vehicles are retired at the end of their lives rather than replaced while the City still maintains the same operational capacity.

Police department EV costs do not include upfitting equipment such as lights, sirens, and radios.

Tesla reports that ancillary lighting and cabin air conditioning/heating do not require much energy, particularly if high efficiency heat pumps are used. However, cabin heating using resistance heating does draw significant amounts of power. One advantage of EVs is that they can provide power to equipment, lifts and lights without needing an engine to be idling.

Electric vehicles typically charge where they park. For light-duty EVs, L2 charging adds 10-20 miles of range per hour and can recharge a battery in 6-12 hours. Larger vehicles have bigger batteries and need either more time to charge (8-to-12 hours) or to be charged at a DCFC.

GHG Emission Reductions

Over this study’s 15-year evaluation period, we estimate that the City can reduce its GHG emissions by 122.8 megatons of carbon dioxide equivalents (MMtCO2e) by converting the City’s fleet to all electric vehicles. The visualization below shows GHG emission reductions on an annual basis, as the current fleet is replaced with EVs following the City’s replacement schedule. Any delays in EV acquisitions will slow the progress of GHG reductions during this period. The time frame can be adjusted using the slider lever to set the view to anywhere between one and 15 years and/or to individual facilities to see the GHG emissions at that level.
