How Does it Work?
To decide if choice is right for you, learn more about the price of natural gas.
Since natural gas is a commodity, its price varies daily based on the effects of weather, supply and demand. Because prices change so much, it's important to look at your gas cost for a full year or two, not just for one month.
The cost of your natural gas supply currently makes up about 75 to 80 percent of your annual gas bill; the rest is delivery charges and taxes. Ameren Illinois' cost for natural gas changes every month and this change is filed with the Illinois Commerce Commission (ICC), which regulates all Illinois utilities and is listed as Purchase Gas Adjustment.
Prices charged by the participating suppliers, as well as the terms and conditions of their contracts with you are not regulated by the ICC. Because of this, suppliers are able to create a variety of pricing offers. Please consider talking to different suppliers to find out about their pricing options, services, incentives and/or promotions.
