Program Overview

ComEd’s RRTP program uses ComEd’s Rate BESH to determine your monthly electricity bills. BESH stands for Basic Electric Service–Hourly Energy Pricing. With it, the price you pay varies from hour to hour based on wholesale market prices.

Program participants like you will have access to hourly prices, and will receive high price notifications and alerts in addition to other useful information. Individual cost savings are not guaranteed and will vary month to month based on weather, market conditions, and usage habits. However, the more participants avoid using electricity when hourly prices are high, the more they can potentially save with ComEd RRTP.

Since the program began, RRTP participants have experienced a savings of more than 15% off the electricity supply portion of their electricity bill, as compared with what they would have paid with ComEd’s fixed-price rate. Individual bills will vary month to month, based on weather, market conditions and your usage habits. Generally, the more you avoid using electricity when prices are high, the more you potentially could save with real-time pricing.

Other Potential Benefits

  • Helps reduce carbon emissions that contribute to global warming.
  • Helps ease stress on the power distribution system during high demand periods.

Program Details

“There’s no cost for exchanging your old meter for the new hourly recording meter, and there’s no additional monthly fee for your new meter.”

Enrollment in this innovative program requires the installation of an electric meter capable of measuring and recording electric usage in hourly intervals. Other than your current monthly standard metering charge, there is no additional monthly meter lease fee for this hourly recording meter and you will not pay a fee for exchanging the meter. The exemption from the monthly meter lease fee and the meter exchange fee only applies to the first meter. If a customer has more than one meter participating in the program at their premises, this customer is subject to a regular monthly meter lease fee and a meter exchange fee for each additional hourly recording meter. Each meter associated with your ComEd account must be exchanged for an hourly recording meter in order to participate in the RRTP program.

Effective with the July 2012 monthly bills, RRTP participants will be charged an additional fee of $0.39 per month to participate in the program. This fee is subject to change as allowed by the Illinois Public Utilities Act.

RRTP participants must also remain in the program for at least 12 consecutive monthly billing periods. Thereafter, participants are free to leave the program if they wish..

Electric Vehicle Owners

The ComEd Residential Real-Time Pricing program is an hourly electricity pricing option that could reduce the cost of charging your electric vehicle (EV).  Hourly electricity pricing lets you pay less for electricity during off-peak times such as nights and weekends. By plugging in during off peak times you can take advantage of lower electricity prices and reduce the overall cost of car ownership.  Visit the ComEd EV Cost Calculator to learn how to maximize potential savings.

Load Guard

Load Guard is a service offered to all ComEd RRTP participants with a central air conditioner who are also enrolled in ComEd’s Central Air Conditioning Cycling (AC Cycling). Load Guard runs from May 1 through September 30. With Load Guard you choose the price level at which Load Guard automatically moderates your central AC usage during high-priced hours. When the price level is reached, Load Guard switches your central AC into a conservation mode for a two-hour period. During this conservation mode, your air conditioner’s compressor will cycle off and on every 15 minutes. There are currently two Load Guard options:

  • Cooler for the planet. Choosing this setting activates the two-hour AC conservation period whenever the price hits 10 cents. You’ll use less electricity during times of high demand, which helps reduce the release of emissions that contribute to global warming.
  • Cooler for your home. Choosing this setting activates the two-hour AC conservation period whenever the price hits 14 cents. This is a good choice if you prefer a cooler indoor temperature, but still want protection against high electricity prices.


Elevate Energy

Elevate Energy (formerly CNT Energy) is the current administrator of the ComEd Residential Real-Time Pricing (RRTP) program. As an affiliate of the Center for Neighborhood Technology, Elevate Energy is a Chicago-based nonprofit organization dedicated to smarter energy use for all. The organization has been involved in real-time pricing since ComEd first launched a pilot program in 2003. Elevate Energy (then called the Community Energy Cooperative) worked with ComEd to provide high quality customer support, and that successful pilot program became the model for the RRTP program that exists today. The RRTP team at Elevate Energy looks forward to continuing to help Illinois households get the best possible value from hourly electricity pricing.
