Save up to 40% off the regular residential rate when you enroll in this rate and charge your vehicle at night or on weekends.  

The Electric Vehicle Rate, D1.9, is a time-of-use rate that offers lower prices for energy used in off-peak hours – between 11 PM and 9 AM Monday through Friday, or any time on Saturday and Sunday. Enrollment in the Electric Vehicle Rate (D1.9) requires the installation of a separate meter and a Level 2 Electric Vehicle charger (EVSE).  

For a limited time, Detroit Edison will offer up to $2,500 off the cost of a Level 2 EVSE for the first 2,500 customers who purchase a plug-in electric vehicle and enroll in the D1.9 rate.  Applications for this pilot program will be available later in the year.  To be notified when the program is available, please join our mailing list.

Use our EV Calculator to calculate your potential cost savings on the D1.9 rate.

Detroit Edison's electric rates are approved by the Michigan Public Service Commission (MPSC).  The D1.9 rate was approved by the MPSC on Aug. 10, 2010. These prices do not include applicable surcharges and taxes. Rates may change by MPSC order.

*Prices include energy and distribution charges only.

Benefits of "off-peak charging"

Off-peak charging is better for both the customer and the utility company. 

• Save money.  By enrolling in the EV rate and charging during the off-peak period, you will save up to 40% off the cost of charging the battery on the regular residential (D1) rate. 
• Extend the life of your battery. Initial research indicates that charging your battery near to the time you will use it significantly extends the life and health of the battery.
• Reduce infrastructure upgrades.  Use existing capacity of the electrical grid during off peak time, eliminating the need to built additional capacity to our system or new power plants, which benefits all of our customers.
