ComEd's new tariffed Purchased Electricity Charges, which reflect the majority of the total price to compare, are as follows:

Purchased Electricity Charges (PECs) are designated on retail customer bills as the Electricity Supply Charge. PECs include Supply Base Uncollectible Cost Factors (Supply BUFs) and PECs incorporate Incremental Supply Uncollectible Cost Factors (ISUFs)

The total price to compare will include the PECs listed above, transmission, and reconciliation (the PEA)

ComEd also said that an update to its bypassable transmission charge results in a "negligible" change for the average residential customer.

For comparison, the current ComEd Purchased Electricity Charge for residential customers is 6.529 cents per kWh, and 6.482 cents per kWh for Watt-hour Non-Electric Space Heating.
