Commercial Energy Management in the Collar Counties
Collar Counties is ComEd territory inside PJM — ComEd transmission zone. ComEd delivers the power and maintains the wires whoever supplies it, so competitive supply carries no reliability consequence — only a lower price.
How Energy Buying Works in Collar Counties
Will County's intermodal terminals move more containers than any inland facility in North America, and the warehousing that grew around them — through Joliet, Aurora and Elgin — is now the defining commercial load of the collar counties. Waukegan adds pharmaceutical and industrial demand of a very different character. All of it is ComEd, in the PJM ComEd zone, on the same delivery classes as Chicago. The distinction that matters is operational: distribution facilities out here can genuinely shift load, which makes capacity peak management and demand response viable in a way they are not for a downtown Chicago office tower.
Illinois opened to competition in 1997, but the terms are set territory by territory, not statewide. ComEd's distribution rates, its default supply price and its rate schedules are all set independently of the other utilities in Illinois — which is why an offer that is genuinely competitive in one part of the state can be mediocre here. Everything on this page is scoped to ComEd specifically.
ComEd Commercial Rates
Which schedule you are on sets the shape of the bill before a single kilowatt-hour is priced.
| Schedule | Typically covers |
|---|---|
| Small Load Delivery Class | accounts under 100 kW |
| Medium Load Delivery Class | roughly 100 to 400 kW |
| Large Load Delivery Class | above 400 kW |
| Very Large Load Delivery Class | the largest industrial sites |
Schedule names, demand thresholds and eligibility rules change with each rate case, and the schedule an account was originally placed on is frequently no longer the one that fits it. We verify yours against the actual bill rather than assuming — that check is free, and it is where a meaningful share of the savings on this page comes from.
