Understanding Illinois Pricing

Two Wholesale Markets

ComEd (Chicago area) operates in PJM, while Ameren (downstate) is in MISO. This means pricing dynamics differ between regions. Chicago often sees higher capacity costs due to PJM market structure.

Municipal Aggregation

Many Illinois municipalities offer opt-out aggregation programs. However, commercial accounts with significant load can often beat aggregation rates through direct supplier negotiation.
