Every month, we file a gas supply charge with the Illinois Commerce Commission. It is the price customers pay for gas purchased from Nicor Gas. As a regulated utility, Nicor Gas does not profit from the sale of natural gas. The price we pay for gas is passed on to our customers without markup.
Customer Select® is all about choices. It's a voluntary, free program offered by Nicor Gas that allows you to choose your natural gas supplier. Depending on the supplier, you will find some offers that lock in your natural gas price and others that compete with Nicor Gas' monthly gas supply charges. By comparing offers and making the choice that's best for you, you may be able to save money on the cost of your natural gas.**
**Savings may depend on several factors including the amount of gas you use, the terms of your agreement with your supplier, and the natural gas market.
Whether you choose a new supplier or continue purchasing your gas from Nicor Gas, you're still a valued Nicor Gas customer! We will continue to deliver your gas through our reliable pipeline system, and we'll respond to all natural gas emergencies.To obtain more information about the residential and small commercial choice program, you may contact the Illinois Commerce Commission at 800.524.0795 or by visiting the Commission's website at www.icc.illinois.gov.
Natural gas is a commodity. And its price goes up and down according to supply and demand across the country. There are several factors that influence supply and demand, such as the economy and weather, and these factors ultimately set the price of gas.
The national factors impacting supply are:
Generally, natural gas production has kept pace with rising demand; however, the national market price of natural gas can increase, sometimes greatly, as a result of short-term supply disruptions.
Storage levels of natural gas on a national level have a dramatic impact on gas costs. Colder than normal weather, particularly early in the heating season, could cause storage levels to be drawn down at an accelerated pace this winter, further impacting prices.
The national factors impacting demand are:
Weather has the strongest impact on gas prices and is also the most difficult to predict. Not only do weather conditions in the Midwest impact natural gas prices, but so does weather throughout the country, particularly the eastern U.S. where there is large potential for natural gas consumption.
Economic factors can cause some industries to lose business to foreign competitors, impacting U.S. industrial production. Decreased industrial demand for natural gas could have a moderating effect on gas prices.

No. Natural gas is a commodity and its price is determined by the market, based on several factors:
When Nicor Gas buys gas on your behalf and delivers it to your business, we charge you exactly what we paid for it – we are not allowed to mark it up, by regulation of the Illinois Commerce Commission.
1. Natural gas is a commodity, so prices fluctuate based on several factors. We have taken action to help lessen the impact of market prices by filling our underground storage fields during summer months when gas prices have typically been lower, using financial purchasing instruments and hedging. Taken together, these actions account for about three-quarters of the gas needed for the winter season.
2. We have developed a new Bill Planning Guide that will help you get an idea of what your upcoming bills might be.
3. Nicor Gas offers payment programs, such as the budget plan that allows you to spread your payments over a 12-month period, with adjustments up or down every four months to correct for future gas prices and your usage. Your monthly bill must be less than $4,000 to qualify.
