In 2020, the Windham County Sheriff's Office endeavored to test an all-electric vehicle in a law enforcement setting in Vermont. This page is intended to serve as a resource for the public as we evaluate the vehicle, as well as a resource for other law enforcement agencies looking to use electric vehicles (EV) or other alternative energy vehicles in our applications. We will continue to update it during this pilot project.

Sheriff Mark Anderson had the opportunity to visit Norway in 2019 as part of an international training opportunity. During his time there, he was exposed to hybrid and EVs. This sparked his interest in the use of a hybrid or non-petroleum powered vehicle in a law enforcement context.
When we talk about police package vehicles, its important to discuss what is different with them. They often come with increased braking capacity, suspension, and handling compared to standard models. They have interiors that are easily cleaned and sanitized (plastic & vinyl versus cloth). They have wiring prepared for installation of lights, sirens and radios. Finally, they have aftermarket equipment designed to be installed based on bolt patterns, layouts and designs.
The Windham County Sheriff's Office planned to purchase three vehicles during 3-4Q FY2019-2020:
Discussing possibilities of standard civilian package vehicles, we learned that the available supply was limited (like toilet paper). As we found comparable vehicles available, we found they were quickly purchased from dealers. We purchased a used Ford Taurus which satisfied our administrative vehicle purchase at a reduced cost from our plan. We applied for a grant to purchase the truck. We evaluated the transport vehicle which we intended to repurpose for patrol and extended its current use another year when we expected those types of vehicles to be available again.
We reviewed Tesla's website, which advertised a 4-6 week delivery from order. We began evaluating the cost aspect and researching if EVs were even used in a police context. We were familiar with agencies in Vermont and nationally using hybrid vehicles, but unaware of electric at that point. No state contract existed with Tesla for vehicle purchases.
A variety of agencies in the United States have deployed Tesla's in a police context. One document found suggests twelve agencies, though we became aware of that after our purchase. Through our initial an internet search, we found the Fremont CA Police Department purchased used Tesla Model S for patrol. We also found the Bargersville IN Police Department, which had photographs posted online of their Tesla Model 3 showing installation of law enforcement equipment and use in a patrol capacity.
Sheriff Anderson spoke with the Bargersville PD, asking questions about expenses, maintenance, upfitting, operation constraints, and more. Some of the critical takeaways from the initial conversation was: 1) the operating costs they experienced resembled the cost estimates we anticipated 2) charging infrastructure was a critical consideration in evaluating how they'd work for us.
We informally spoke with New England owners about their experiences with the cars. Rear-wheel drive was reported as problematic in snow. All wheel drive with snow tires was reported as usable. Some people told us they had no issues on Vermont roads, while others told us we wouldn't be breaking trails (but then again, we were told that about rear-wheel drive Crown Victorias which we inevitably broke trails with). We learned that the batteries were affected by the cold, by a reduction as much as half the distance of the battery, whiles others shared approximately 20% reduction as a result.
This graph shows the average cost of fuel divided by the mileage, based on the year the vehicle was manufactured. This is organized by Electric Vehicles (EV) and Internal Combustion Engine (ICE)/Gas powered cars.
2013: $0.54 per mile
2016: $0.48 per mile
2017: $0.48 per mile
2018: $0.24 per mile
2019: $0.72 per mile
2020 (EV): $0.02 per mile
2020 (ICE): Pending
Assumptions:1) An average cost of gas of $2.41 based on the AOT's Fuel Price Adjustment from 2015 to 2020) The mileage of a vehicle from 2015 to 2020 was the same each year 3) An average of 10MPG including idling, across each vehicle.
