How Commonwealth Edison (ComEd) and Retail Suppliers Work Together
ComEd serves Chicago and northern Illinois — the largest commercial electricity market in the Midwest.
ComEd handles distribution. ARES (alternative retail electric suppliers) compete for commercial supply. The supply portion of your bill — typically the largest single line item for commercial accounts — is where retail competition applies. That's the piece a broker targets.
ComEd delivery rates are regulated by the Illinois Commerce Commission. The Hourly Pricing program applies to some large commercial accounts.
