ComEd Nonresidential Delivery Service Charges by Delivery Class, 2024 to 2027

ComEd's filed nonresidential delivery service charges for all eight metered delivery classes, 2024 through 2027: customer, metering, and demand charges per kW, each cited to its informational sheet, with the ADJ mechanism explained honestly.

UPDATED SEP 02 2026

Every ComEd business account sits in one of the nonresidential delivery classes, and the delivery class decides what a kilowatt of peak demand costs. This page is the filed record: the delivery service charges for all eight metered nonresidential delivery classes, from Watt-Hour to Railroad, for every billing period the committed filed sheets cover, which today means 2024 through 2027. Every number is read from ComEd's informational sheets as filed with the Illinois Commerce Commission, each table names its sheet, and the whole record, 2024 columns included, is downloadable as CSV.

The same warning that governs the residential record governs this one. Every filed value prints with "& ADJ" beside it, and the base alone never reconciles to a bill. The worked example below shows the gap on a reconciled bill: a $12.71 filed base that billed at $14.59 per kW.

The charges and the classes

The sheets print up to six components per class, under these abbreviations:

  • CC, the Customer Charge, dollars per month.
  • SMSC, the Standard Metering Service Charge, dollars per month.
  • SV DFC and PV DFC, the Distribution Facilities Charge in dollars per kW of billed demand, at secondary and primary voltage. This is the line most people mean by the demand charge. The Watt-Hour class has no demand meter and pays a volumetric DFC in dollars per kWh; Railroad pays a single DFC per kW.
  • PV TC, the primary voltage Transformer Charge, dollars per kW.
  • IEDT, the Illinois Electricity Distribution Tax Charge, dollars per kWh.

High Voltage accounts additionally carry HV DFC and HV TC rows that depend on whether the account's maximum kilowatt demand exceeded 10,000 kW in the prior twelve months; those rows are in the tables and the CSV under their own labels.

Which class an account is in is set by its size and voltage. The demand charge calculator applies the filed rates below, factors included, to a peak demand and class.

The filed charges for 2025, 2026, and 2027

The values for Watt-Hour, Small Load, and Medium Load are from the 5th Revised Informational Sheet No. 64.3; Large, Very Large, and Extra Large Load from the 5th Revised Informational Sheet No. 64.5; High Voltage and Railroad from the 5th Revised Informational Sheet No. 64.7. All three sheets were filed February 21, 2025 and effective February 28, 2025 under the ICC's order of January 16, 2025 in Docket No. 24-0378. Each printed value carries "& ADJ".

Three things the columns show without any interpretation. The Small through Extra Large SV DFC bases dip from 2025 to 2026 and rise again in 2027, so a business comparing this year's bill to last year's is comparing two different filed bases before anything about its own usage changes. The High Voltage SV and PV DFC bases fall sharply from 2025 to 2026, 17.65 to 10.72 and 22.18 to 12.10 per kW, as printed on Sheet No. 64.7; this record reports the printed columns and does not speculate about the reason. And the per kW bases barely change with class size: a site four times larger pays roughly the same filed rate for every kilowatt of peak, which is why the demand line scales with the shape of demand rather than the size of the business.

The 2024 columns

The 2024 billing periods are printed on the 3rd Revised Informational Sheets No. 64.2, 64.4, and 64.6, filed December 23, 2024 and effective January 1, 2025 pursuant to the ICC's Order on Refiled Plan dated December 19, 2024 in Docket Nos. 22-0486/23-0055/24-0181 (Consol.). As on the residential sheet, each 2024 row prints four columns: the charges applicable in January, in February through April, and in May through December, plus a separate "2024 Charges per Final Order" column from the consolidated dockets. All four columns for all eight classes, 192 values, are in the CSV with their sheet citations rather than printed here as twenty four more tables. One example row, Small Load SV DFC: 11.02, 11.02, 11.53, and 12.05 per kW.

A filed base is not the rate on the bill

Every value above prints with "& ADJ" on the filed sheet. The adjustment factors are filed on their own monthly and annual sheets, and the rate a bill applies is the base run through them. On the ComEd Small Load bills we have reconciled to the cent, the 2025 filed SV DFC base of $12.71 billed at an effective rate of about $14.59 per kW, and a 40.91 kW peak produced a $596.88 charge; on a 2026 bill the $12.50 base billed at about $12.93 per kW, and a 46.20 kW peak produced a $597.37 charge. The base moved 21 cents between those years; the effective rate moved a dollar sixty six, because the factors moved too.

So a quote of any base above as "ComEd's demand charge" is a quote of a rate no customer has ever paid, and a bill that does not match a base is not evidence of an error. The 2027 columns are filed bases only: no 2027 adjustment factors exist yet, so no honest 2027 effective rate can be computed by anyone, this site included.

What this record does not hold

Three absences, stated rather than filled in. The sheets governing 2022 and 2023 were canceled by the revisions above and are not in any committed source here, so this record begins at the 2024 columns. The lighting delivery classes, Dusk to Dawn, General Lighting, and Fixture-Included Lighting with its per fixture charge schedule, sit on Sheets No. 64.8 through 64.10 and are not included in this record. And the adjustment factor values themselves are a separate, monthly record that this page deliberately does not reproduce; the two reconciled effective rates above are offered as evidence of the mechanism, not as a factor table.

Where these numbers come from

Every value is read from ComEd's published Schedule of Rates for Electric Service, Ill. C.C. No. 10, as retrieved from ComEd's own ratebook download on August 17, 2026 (the full PDF's sha256 is 265c867b535447043bd1069898884288cb86beda446f0a462f7ce91fa4cbee71): Sheets No. 64.2 and 64.3 on ratebook pages 842 and 843, Sheets No. 64.4 and 64.5 on pages 844 and 845, and Sheets No. 64.6 and 64.7 on pages 846 and 847. A 2025 edition of the same ratebook, held separately, prints the same revisions of all six sheets, so the two committed copies agree. The Small Load column is additionally verified against real ComEd bills reconciled to the cent, one 2025 and one 2026.

The residential classes have their own filed record, and the supply half of the bill has the filed supply charges by customer group.
