Power Smart Pricing - A Smart Electricity Rate from Ameren Illinois


How it Works

About Power Smart Pricing

Power Smart Pricing is an hourly electricity pricing program for residential customers served by Ameren Illinois. The price you pay for electricity will vary hour by hour based on actual market prices. Power Smart Pricing uses “day-ahead” prices, meaning the price for each hour of the day is set the night before. Your bill is calculated using the hourly, day-ahead market prices and your corresponding hourly usage. If you are able to shift your electric usage to different times of the day you can take advantage of lower priced hours. You can manage your electricity costs by using energy wisely during hours when prices are higher.

About Hourly Prices

Hourly Prices Chart

*Based on average prices for January 1, 2015, through August 24, 2018. Non-summer months include October-May. Summer months include June-September. Depending on market conditions, prices can vary significantly from this pattern. Savings cannot be guaranteed.

Summer Price Patterns

Electricity prices typically fluctuate most during the summer months, driven in large part by demand for air conditioning. Prices are usually highest during the late afternoon and tend to peak between 1 p.m. and 5 p.m. Higher overall prices tend to occur on days when the weather is particularly hot. Prices are generally lower on weekends and holidays and on days when the weather is cool. You can manage your costs by keeping these price patterns in mind and shifting electricity usage accordingly.

Fall, Winter, and Spring Price Patterns

Compared with summer prices, fall, winter, and spring prices are generally lower, and the price pattern is more stable. During the cooler months, there tends to be a small price spike in the morning and then again in the evening. On many fall, winter, or spring days the hourly price of electricity remains low all day long.

Weather Can Impact Hourly Prices

The weather can have a big impact on the hourly price of electricity, particularly during the summer when air conditioner usage drives up demand for electricity. This is why summer electricity prices tend to be highest during the afternoon. During the winter months, continuous days with very cold temperatures can also drive up natural gas prices, which can impact the hourly prices on Power Smart Pricing.

Checking Hourly Prices

Power Smart Pricing uses day-ahead, hourly market electricity prices. Each evening after 5 p.m., the prices for the following day are available online and by phone.

Price Alerts

To help get the most out of Power Smart Pricing, participants will receive an alert between 5 p.m. and 10 p.m. if hourly electricity prices will be 9 cents per kWh or higher for any number of hours the following day. This is most likely to occur on hot summer days, but could occur on any day of the year. You can receive alerts by phone, text message, or email.

Program Details

Length of Program

You can leave Power Smart Pricing at any time by contacting us or by signing up with a Retail Electricity Supplier (RES). However, we highly recommend you remain in the program for at least one year as the pricing pattern and your usage change with the seasons. For example, you may see lower savings in the summer, and then see higher savings when the weather cools down. If you leave Power Smart Pricing, your account will be unable to rejoin an Ameren Illinois hourly rate for one year (12 billing cycles).

Participation Fee

Power Smart Pricing participants are charged a monthly participation fee of $2.25 which is included on your electricity bill.

Your Billing Information

You will continue to receive your monthly utility bill from Ameren Illinois and you will remain on the same billing schedule. You will be billed on hourly pricing after the interval data recording meter is installed and a full month of interval data is recorded, but no sooner than the end of the monthly billing period. Once your account bills, you can use the Power Smart Pricing website to view more detailed information about your hourly usage and costs.

Moving or Selling Your Home

If you move or sell your home, the new owner or resident will automatically be put on the standard BGS-1 rate. If you move to another home served by Ameren Illinois, you will need to re-enroll in Power Smart Pricing in order to receive the advantages of hourly electricity pricing at that location.
