Electric Choice Basics
Your electricity service is made up of three parts: (1) the electricity itself is provided by an electricity generator and is sometimes referred to as electricity "supply" or "generation", (2) the "transmission" of that electricity from the generation facility to your local utility, and (3) the "distribution" or "delivery" of the electricity by the utility over the electric lines that lead to your business or home. In the past, the utility provided all three parts of your electric service (supply, transmission, and distribution).
Customers in the Ameren Illinois, ComEd, and MidAmerican service territories have the ability to choose who provides the supply portion of their electric service.1 Electric supply may be sold by either the utility or Alternative Retail Electric Suppliers (ARESs).
