ComEd Commercial Energy Market & Utility Context
ComEd is the utility context for commercial accounts across Cook County, DuPage County, Kane County, and surrounding areas. This page uses canonical Market Monitor utility evidence; supplier eligibility, ZEN serviceability and executable pricing still require account review.
Zen Energy's take: Illinois: PJM and MISO demand are both firming. Henry Hub natural gas is rising (+2.4%). Illinois's latest commercial electricity benchmark is 15.19¢/kWh for 2026-07. Illinois uses Electricity + Natural Gas context. A single regional grid signal is withheld because utility territory is required for an accurate grid mapping. Electric choice is available in ComEd, Ameren Illinois and MidAmerican territories. Natural-gas choice is available to eligible Nicor Gas, Peoples Gas and North Shore Gas customers.. Henry Hub is a wholesale natural-gas benchmark and is not a local utility tariff or executable supplier quote.. Executable supplier offers still depend on usage, utility territory, account eligibility and contract terms.. Data confidence is moderate because some applicable public-market inputs are delayed, stale or unavailable.
Opportunity: Current conditions favor continued market monitoring.
