Vehicle cost per mile
The service contract enables agencies to source any available electric vehicle from sedans and SUVs to buses and heavy equipment. The rate per mile to the agency is determined based on the product, charging infrastructure, and expected maintenance costs over the 10-year contract.
When determining which EVs to select for HDOT's initial order in April 2021, Sustainability Partners compared costs for the 2021 Nissan Leaf Plus SV, the 2020 Chevrolet Bolt LT, and the 2021 Tesla Model Y. The comparison chart is to the left.
Cost of EVs as a service compared to purchasing
Using the service contract to bring in the 43 Highways EVs saves HDOT approximately $107,500 on maintenance alone. This is based on annual maintenance cost of $2,500 per vehicle. Savings on gas based on assumption of $2.50 per gallon cost and 22 miles per gallon vs. current electricity rates is $287 per year, per vehicle.
Purchasing 43 EVs outright and install chargers would cost between $2.6 million and $3 million. Cost of the service contract EVs is $200,000 a year for 6,000 miles of use (per EV).
