EV Charging & Rates

Plug-in electric vehicles need to be plugged in to a source of electricity, just like a light or an appliance, to have their batteries charged. And, since electricity is your new fuel for transportation, the rate you pay for electricity will likely become more important to you.


There are two industry-standard levels of charging for most passenger plug-in electric vehicles, as well as a third, fast-charging, commercial option.

Level 1 Charging: 120-volt

Level 1 charging requires access to a standard, grounded, three-prong 120-volt outlet with a ground fault circuit interrupter. Most PHEVs can be fully charged at Level 1 in eight to 10 hours. BEVs can take 12 to 24 hours to become fully charged at Level 1 because of their larger battery size. Level 1 charging has an electric load of 15 to 20 amps; about the same as a large microwave oven.

Level 2 Charging: 240-volt

Level 2 charging requires installation of a 240-volt charging station by a licensed electrician; the load is similar to what is needed for an electric stove or central air conditioning system. Level 2 charging will typically charge an EV in about half the time it takes to charge at Level 1. This type of station may require upgrades to the home’s electrical service. It is recommended that you contact ComEd before installation to verify that local distribution facilities are adequate to serve this additional electrical load.

Level 3 Charging: 440-volt DC Fast Charging

Although a national standard has not been finalized, there is a third charging option known as DC Fast Charging. With a higher power requirement of 440 volts, this option is not typically available to most residences, so DC fast charges are normally built as public charging stations. They are capable of charging an EV in as little as 30 minutes.

Public Charging Stations

While the home is likely to be the primary charging location for most EVs, public charging stations are also available for charging on the road. The number and availability of public stations continues to grow. Find Charging Locations.


Currently, there are three rate options available to ComEd residential customers: ComEd’s fixed-price rate (BES), ComEd's hourly pricing rate (BESH) and a delivery services rate (RDS).* Additional information on rate options can be found in Rates & Tariffs.

Fixed-Price Rate (BES)

With ComEd’s fixed-price rate, or Rate BES (Basic Electric Service), you pay a set price for your electricity supply. This price varies by season; it is adjusted periodically but it does not change from hour to hour or from day to day. You pay the same price for electricity no matter what time of day or which day you use it. View Rate Information.

Hourly Pricing Rate (BESH)

ComEd’s Hourly Pricing program, Rate BESH (Basic Electric Service Hourly Pricing), allows customers to pay the hourly, wholesale market price of electricity. The price varies by the hour, and customers can manage their costs by shifting some of their electricity use to times when the price is lower (typically night and weekend hours).

Customers who sign up for Hourly Pricing have access to tools to help them keep tabs on electricity prices and manage their costs. To learn more about ComEd’s Hourly Pricing program, visit, or contact an Hourly Pricing specialist at 888-202-7787. 

Delivery Services Rate

The RDS (Retail Delivery Services) rate is for customers who elect to have their electricity delivered by ComEd, but have the actual electricity supplied by a certified Retail Electric Service (RES). RES’ provide Illinois consumers with options outside their local utility companies for electricity supply. RES’ are certified by the Illinois Commerce Commission and registered to supply electricity to consumers in your area. Read about Customer Choice.


* Regardless of the rate you choose, all residential customers receive the same delivery services under Rate RDS from ComEd that are reflected on your monthly bill (Customer Charge, Standard metering Charge and Distribution Facilities Charge). These charges finance the maintenance of the poles, wires and services required to deliver electricity to your home and are shown separately on your electricity bill. Your selection of power and energy supplier will not impact the quality of the delivery service you receive from ComEd.

** Even though a majority of RRTP participants have saved money, RRTP may not be right for everyone, and bill savings cannot be guaranteed.
