Residential Rate Program

Drive an EV? Take advantage of the Ameren Illinois EV Rate Program to shift when you charge and save. This optional rate program is for Ameren Illinois residential customers who drive an EV and charge their vehicle at home. Plug in during the preferred time and save on electric delivery fees while you charge.
 

Take Charge of your EV Lifestyle

Your energy usage ebbs and flows with your driving habits, vehicle mileage range and many other lifestyle factors. It is important to know where to charge and when to charge. This program encourages you to charge at home during the preferred charging times from 11 p.m. – 7 a.m.


The facts about our EV Rate Program

While standard delivery service rates always apply, there are different price periods or times of the day that influence your monthly bill while on this rate program:

  • Preferred Charging Period (PCP): 11:00 p.m. - 7:00 a.m. A credit for your electric delivery service is given for every kWh of usage during this period.
  • Non Preferred Charging Period (NPCP): 11:00 a.m. – 7:00 p.m. During the highest one hour of household usage from the billing period that occurs within this timeframe, there will be an additional charge for each kWh used.
  • Morning and Evening: 7:00 a.m. – 11:00 a.m. and 7 p.m. to 11:00 p.m. There are no additional credits or charges for electric usage during this time period.
  • First-year Bill Credit: We understand that it takes time to adjust. To offset potentially higher charges for usage during the NPCP, we offer a monthly bill credit for your first 12 consecutive months enrolled on the EV Rate Program. This will give you time to see how household usage impacts your bill and to make adjustments for maximum savings

If you live in a single-family home, such as a house or a condo, and you charge an electric vehicle at that location you are eligible. 
Residential customers will need to provide the following information to sign up for the EV Rate Program:
  1. Year, make, model, and VIN of EV
  2. Information on charging equipment (Charger manufacturer, model, voltage, and amp rating) 
  3. Certified installer information if applicable, including company information and ICC Docket number
The EV Rate program will only change the way you are billed for the delivery portion of your service, all standard electric supply rates apply. The program was also designed to impact only the new usage that will be added to your bill for EV charging. This means that if you continue your existing electric usage patterns outside of EV charging, your bill for that portion should not change. 

Preferred Charging Period (PCP): A credit for your electric delivery service is given for every kWh of usage during this period.
Non Preferred Charging Period (NPCP): During the highest one hour of household usage from the billing period that occurs within this timeframe, there will be an additional charge for each kWh used.

 

EXAMPLE: EV Peak NPCP Usage Calculation

Assuming Peak hourly usage: 6 kWh
Assuming NPCP charge/kWh = $.65

$.65/kwh x 6 kWh = $3.90 Total Peak Hourly Delivery charge on bill

EXAMPLE: EV PCP Credit Calculation (summer)

Assuming total PCP usage for the billing period: 230kWh

230 kWh x $.02 summer EV credit = $4.60 total Credit on bill

EV peak NPCP usage charge and PCP credit comparison:

   -$ 3.90  Peak Delivery Charge
+$ 4.60  PCP Credit
+$  .70 credit

As you can see the difference between the charge and the credit for this customer would be $.70, meaning they will not see much of a difference in their billing before they add in the extra usage for EV charging. The important piece to remember is that charging overnight helps keep your added EV electric usage costs low.

Yes, as a residential customer you can cancel your enrollment at any time and return to standard billing effective with your next meter reading. You can re-enroll at any time; however, if you cancelled before your first consecutive 12 months were complete, you will no longer be eligible to receive the monthly bill credit.
The EV Rate Program is designed to increase accessibility of EV charging at home and on-the-go. Rate incentives and supplemental line extensions are offered to keep the cost of charging manageable and to reduce the up-front expense of building new charging facilities. The program is designed to encourage customers to charge overnight when the electric grid typically has lower use. This will create grid efficiency that supports downward pressure on all customer rates.
The EV Rate Program is optional. However, we want to spread awareness of the program because it may provide savings to the customer, and it will encourage usage that promotes electric grid efficiency.
