At ComEd, we provide electronic tariff documents (in pdf format) for the convenience of our residential and business customers. Our tariffs are subject to regulatory review and approval by the Illinois Commerce Commission (ICC). However, users of electronic tariffs should note these tariffs are not the official documents and users assume responsibility for reliance upon tariffs in electronic format.
Although ComEd aims to have this information current at all times, it should be emphasized that the rates and provisions in the tariffs are subject to revision. All of the tariffs below have been approved by the ICC. Notification of proposed changes to ComEd's tariffs are not provided on this website.

Rate RTOUPP is a residential elective bundled service pilot starting in June 2020. The pilot is commonly referred to as ComEd’s Time-of-Day Pricing rate. The rate is limited to 1,900 participants and will be operational for at least four years. The rate structure has three different pricing periods with pricing being the highest during the times when electricity market prices are higher (mid-afternoon to early evening) and lowest pricing in the late evening and early morning when market prices are lower. The rate will study if customers lower their usage during the higher priced periods and if plug-in electric vehicle owners are incentivized to charge their electric vehicles when the prices are lowest. Monthly charges applicable under ComEd’s Time-of-Day Pricing rate that are included by reference to this tariff or to other tariffs include the Customer Charge, Standard Metering Service Charge, Distribution Facilities Charge, and Illinois Electricity Distribution Tax Charge (all provided in the Delivery Service Charges Informational Sheets along with other delivery service charges that may apply depending on specific service arrangements); the PJM Services Charge (aka Transmission Services Charge) and Miscellaneous Procurement Charge, Residential Time of Use (RTOU) Electricity Charges and RTOU Purchased Electricity Adjustment Factor (all from Rate RTOUPP).
