Home and Private Workplace EV Charging

$400 Off-Peak Charger Incentives

Benefits

Low Cost – Like paying $1.95/gallon for gasoline.*

Convenient – Can be as easy as charging your phone. Never go to a gas station again.

Effortless – Wake up every morning or end each workday with a full battery.

* A 2026 Tesla Model Y (27kWh/100-mile) using $.24/kwh electricity would cost the same per mile as a 2025 Toyota RAV4 (30-mpg) using $1.95/gallon gasoline.

Wiring Choices

Hardwiring – permanently installed, directly wired to the circuit panel

  • Can charge faster. 
  • Get a clean, professional appearance. 
  • It’s permanent and secure.
  • No outlet involved.

Plug-in – charger plugs into a 240V outlet 

  • Can use an existing outlet (e.g., NEMA 14-50). 
  • Can relocate the charger on site or to a different property.
  • The outlet can serve multiple purposes (e.g., EV charger, generator, power tools, etc.).

    Dynamic Load Management

    If a circuit panel doesn’t have enough capacity to add an EV charger, an alternative to upgrading the panel’s capacity is to install a dynamic load management system, which can be thousands of dollars cheaper.  

    Dynamic load management systems continually monitor the total energy flowing through a circuit panel to ensure total demand stays within the panel’s capacity. If an appliance (like an oven) starts during a charging session, the load management system will automatically reduce power to the charger until the oven turns off. 

    Off-peak chargers automatically pause charging during peak hours (5:00 p.m. to 9:00 p.m. weekdays). Off-peak chargers are ideal for at-home, fleet, and most employee charging.
