According to the Illinois Commerce Commission, ComEd’s energy price is projected to drop to around 5.55 cents per kilowatt-hour, from the current 8.3 cents per kilowatt-hour, that is a 2.75 cent decrease. The ComEd energy price includes the costs of transmitting electricity from power plants over high-voltage lines to the local distribution system.

Contracts municipal politicians and officials in 15 towns negotiated with power suppliers more than a year ago, to lower residents’ electricity bills, will soon exceed the costs ComEd customers pay starting in June.

The price being paid by most residents in Oak Park, which has an energy-supply contract with Integrys Energy Services Inc. until December 2013, is 5.79 cents per kilowatt-hour, 4 percent higher than the projected ComEd charge.

However this is not the case with Realgy Energy Services, they have been and remain below ComEd’s Pricing.

In northern Illinois, all customers pay ComEd to deliver their electricity but are free to choose a supplier to provide the electricity itself. The cost of electricity typically accounts for about two-thirds of an electric bill while delivery charges make up the rest.
