How much does it cost to charge an EV in Maine?


Thinking about the actual cost to charge an EV in Maine, we provide you with a couple of real-world examples:

Example 1: Tesla Model 3

  • Vehicle: Tesla Model 3
  • Location: Central Maine
  • Utility Rate: Central Maine Power (CMP) residential rate
  • Charging Method: Home charging using a Level 2 charger
  • Electricity Rate: $0.15 per kilowatt-hour (kWh)

Here is our basic calculation to determine the charging cost statewide for Tesla’s cheapest model:

  • Total energy required for a full charge: 263 miles / 4 miles per kWh = 65.75 kWh
  • Charging cost: 65.75 kWh * $0.15 per kWh = $9.86

Example 2: Ford Mustang Mach-e

  • Vehicle: Ford Mustang Mach-e
  • Location: Maine-upper I-95 corridor
  • Utility Rate: Emera Maine residential rate
  • Charging Method: Public fast charging station (DC Fast Charger)
  • Electricity Rate: $0.25 per kilowatt-hour (kWh)

Using the same formula, our calculation for a Ford Mustang Mach-e would be:

  • Total energy required for the charge: 305 miles * (80% – 10%) / 3 miles per kWh = 6.97 kWh
  • Charging cost: 6.97 kWh * $0.25 per kWh = $1.74

Note: Electricity rates and charging costs can vary based on utility providers and specific plans. It is urged to confer with the utility provider and check the charging costs associated with the chosen EV and charging method for accurate and up-to-date information specific to Maine.
