Below are ComEd's current electric service tariffs for nonresidential customers. ComEd's tariffs are subject to regulatory review and approval by the Illinois Commerce Commission (ICC).
ComEd provides Internet access to its tariff documents for the convenience of its customers. 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.
Even though 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 and notification of proposed changes to ComEd's tariffs are not provided through this web site.

- Rate RDS – Retail Delivery Service
The charges and terms of Rate RDS are applicable to all retail customers in ComEd’s service territory for delivery service. For retail customers taking a bundled service from ComEd under one of ComEd’s Basic Electric Service tariffs, the charges for the delivery of electric power and energy contained in Rate RDS are applicable for such service. The charges for the delivery of electric power and energy contained in Rate RDS are also applicable to retail customers taking supply service from a Retail Electric Supplier (RES) or from ComEd under Rider PPO-MVM.
- Rate BES – Basic Electric Service
Rate BES is a bundled service tariff applicable to most nonresidential retail customers with loads less than 100 kW, or with loads between 100 kW and 400 kW that are not declared competitive, that have not elected service from a RES, under Rider PPO, or under Rate BES-H. Monthly charges applicable under Rate BES that are included by reference to other tariffs include the Customer Charge, Standard Metering Service Charge, and Distribution Facilities Charge (all from Rate RDS); the PJM Services Charge (aka Transmission Services Charge); Retail Purchased Electricity Charges; and Purchased Electricity Adjustment Factor are all from Rider PE. In addition, other generally applicable charges, such as State taxes, apply each month and charges for nonstandard services may also apply for customers that elect such services.
- Rate BES-H – Basic Electric Service – Hourly Energy Pricing
Rate BES-H is a bundled service tariff applicable to retail customers for which electric service has been declared competitive and customers that self-generate electricity and that have not elected service from a RES. It is also available to other customers that elect hourly energy pricing. Monthly charges applicable under Rate BES-H that are included by reference to other tariffs include the Customer Charge, Standard Metering Service Charge, and Distribution Facilities Charge (all from Rate RDS); the PJM Services Charge (aka Transmission Services Charge) and Miscellaneous Procurement Charge; Capacity Supply Charge; Hourly Energy Supply Charges, and Purchased Electricity Adjustment Factor are all from Rate BES-H. In addition, other generally applicable charges, such as State taxes, apply each month and charges for nonstandard services may also apply for customers that elect such services.
- Rider PE – Purchased Electricity
Rider PE describes ComEd’s obligations with respect to the procurement of electricity at wholesale and certain services through PJM administered markets under the Illinois Power Agency Act. Rider PE also describes the methodology that ComEd uses to determine retail charges to recover the costs that ComEd incurs for the electricity and transmission services procurement, with no mark or return for the prices paid by ComEd. Beginning with the June 2008 monthly bill these Retail Purchased Electricity Charges will apply.
- General Terms and Conditions
