Q 2:

What are the benefits of Guaranteed Bill?

  • Makes monthly budgeting easy
  • Know exactly how much you’re paying for gas each month 
Q 3:

How is my company’s monthly amount calculated?

A 3:

Your Guaranteed Bill amount is customized for you based on a proprietary formula that looks at several factors, including, but not limited to, your company premises' prior gas usage, wholesale gas costs, and normal weather conditions.

Your Guaranteed Bill customized monthly amount includes:

  • All natural gas-related costs
  • Any program administration fees
  • Any applicable taxes 
Q 4:

You’ll be responsible for the period of time you are on the plan. Be sure you understand your cancellation terms before you enroll.
Q 8:

What is rescission and how is it different from cancellation?

A 8:

Rescission means "to take away" or "to take back".The rescission of a contract returns the parties in the contract to the positions they would have occupied if the contract had not been made. If you decide to rescind your contract, you have 10 days from the postmark date of the gas utility letter to request rescission of your company’s contract with Illinois Energy. If a contract is rescinded, you’ll remain a customer of the energy supplier you had contracted with prior to enrolling in the Illinois Energy contract.

To rescind your contract, you can call us at 1.877.292.9363 or the utility, as follows:

  • In Nicor Gas territory, call 1.888.NICOR4U (1.888.642.6748)

Your company will become active in the Guaranteed Bill program at the first meter reading after one of the following dates, as applicable: (i) the date that the utility accepts your company into its Choice program, or (ii) the date that the utility and/or Illinois Energy processes your company's enrollment or switch to the plan. Your company will receive its first Guaranteed Bill charges approximately 30 days after it becomes active in the Guaranteed Bill program.

Q 10:

What happens if my company pays more or less than its Guaranteed Bill amount in a given month?

A 10:

The amount you overpay will be considered a credit, which can be applied toward your next month's Guaranteed Bill amount if you so desire. Underpaying will result in a past-due balance that will appear on your next month's bill. Your company will still be responsible for any past-due balance and any potential late-payment fees (1.5% of your outstanding balance). Illinois Energy reserves the right to terminate Guaranteed Bill service due to nonpayment.

  • If you accept the amount and terms, do nothing and your 12-month Guaranteed Bill amount will go into effect automatically under the terms set forth in that notice.
  • If you don't want your company's agreement to renew, call us at 1.877.292.9363 within 30 days of the postmarked date of that notice to cancel your agreement or send written notice to Illinois Energy, PO Box 3066, Naperville, IL 60566-7066.

Once you have enrolled in the Guaranteed Bill program, we’ll request the utility issue your company a refund check so the funds can be used toward future Guaranteed Bill amounts. 

Q 13:

Is the Guaranteed Bill program a savings plan?

A 13:

The total Guaranteed Bill plan charges over the term of the plan agreement may be higher than the total cost of traditional utility service over that same period and customers may not save money on the plan.

Q 14:

Can my company be on another Choice program and request to go on the Guaranteed Bill program?

A 14:
No. If you decide to enroll your company in the Guaranteed Bill program, you agree to cancel your company’s contract with your current provider.

Q 1:

How does the TruBalance Plan work?

A 1:

Illinois Energy's TruBalance Plan is a combination of a variable priced product and a fixed price product. This means that half of your company’s monthly gas usage is billed at a fixed price per therm for one year, and half of the monthly usage is billed at the first-of-month Bidweek Survey index price, published in Natural Gas Intelligence, plus a set cost per therm.

Half of your usage is insulated from fluctuating natural gas prices because your price per therm remains unchanged. Half of your usage is billed based on prevailing monthly market prices.

Q 2:

What are the benefits of the TruBalance Plan?

A 2:

By blending fixed and variable prices into a single plan, your company gets some degree of flexibility and price certainty.

Q 3:

How is the TruBalance Plan price determined?

With the TruBalance Plan:

  • Half of your company’s monthly usage is locked in at a fixed price per therm. That fixed price set at the time of your enrollment and remains unchanged for a year. 
  • The other half of your company’s monthly usage is calculated from a monthly, variable market-based price plus a set cost per therm.

For more information about how our company's monthly bill is calculated, click here to see the Commercial TruBalance terms.

Q 4:

How long is the TruBalance Plan quote good for?

A 4:

Once you’ve been given a TruBalance Plan quote for half of your usage, you will have until the end of that business day to enroll and lock in the quoted price. If you choose not to enroll until a later date, your company’s TruBalance Plan quote may change.

Q 5:

What happens at the end of my company’s TruBalance Plan contract?

A 5:

Before your 12-month TruBalance Plan agreement ends, we will send your company a written renewal notice including your updated terms and conditions for another 12-month term, subject to eligibility. That notice will include:

  • Your company's fixed price per therm — for half of your usage — for the next 12 months
  • Your company's set cost per therm that will apply to the monthly index gas rate, and 
  • Any changes to the terms and conditions of the TruBalance agreement

To discontinue the program, simply call or write us, and we will change your company’s service to one of our other price protection plans, if eligible, or return it to utility service at the beginning of the next billing cycle. To cancel, please call us at 1.877.292.9363.

Q 10:

What is rescission and how is it different from cancellation?

A 10:

Rescission means "to take away" or "to take back". The rescission of a contract returns the parties in the contract to the positions they would have occupied if the contract had not been made. If you decide to rescind your Commercial FlexPlan contract, you have 10 days from the postmark date of the gas utility letter to request rescission of your company’s contract with Illinois Energy. If a contract is rescinded, your company will remain a customer of the energy supplier you had contracted with prior to enrolling in the Illinois Energy contract.

To rescind your contract, you can call us at 1.877.292.9363 or the utility, as follows:

Q 1:

How does the PriceCap plan work?

A 1:

Illinois Energy's PriceCap provides both certainty and flexibility.   Your company is protected if natural gas prices rise and is afforded the flexibility of paying a lower price if monthly market gas prices on the plan decrease.  Your company’s guaranteed maximum price per therm  is determined at the time of enrollment. Your company’s monthly price is based on monthly market natural gas prices plus a fixed cents per therm charge.  You will also pay a monthly administrative charge of $1.99. Your company will always pay the lower price per therm amount- guaranteed - during your 12-month term.


Q 2:

How are my company’s PriceCap plan charges determined?

A 2:

With the PriceCap plan, your company will pay no more than the set maximum per-therm price.  This price is set by Illinois Energy at the time of enrollment.  If the market-based price on your plan falls below your maximum per-therm price, your company will pay the lower amount.  Illinois Energy use the first-of-month Bidweek Survey index price at the Chicago Citygate published in Natural Gas Intelligence plus a fixed cents-per-therm charge to determine the market-based price. This index is commonly used in the natural gas industry to establish monthly pricing. The plan also includes a $1.99 monthly administrative fee.

Q 3:

What is the market price Nicor Advanced Energy uses for the PriceCap plan?

For the PriceCap plan, Illinois Energy uses the first-of-month Bidweek Survey index price at the Chicago Citygate published in Natural Gas Intelligence (NGI) plus a fixed cents per therm charge. This index is commonly used in the natural gas industry to establish monthly pricing.

Q 4:

How long is my company’s PriceCap quote good for?

A 4:

Once you have been given an Illinois Energy PriceCap guaranteed per-therm quote for your company, we encourage you to enroll by the end of that day to lock in that price. If you choose to wait to sign up until a later date, please be aware that your PriceCap quote may change.

Q 5:

How long will my company’s PriceCap plan agreement last?

A 5:
PriceCap is a yearly agreement. Your agreement lasts for 12 months.
Q 6:

When will my company’s PriceCap plan begin?

A 6:

After you enroll, your company will receive at least one more regular gas bill, which your company will be responsible for paying. Your company will become active in the PriceCap program at the first meter reading after one of the following dates, as applicable: (i) the date that the utility accepts your company into its Choice program, or (ii) the date that the utility and/or Illinois Energy processes your company's enrollment or switch to the plan. Your company will receive its first PriceCap charges approximately 30 days after it becomes active in the PriceCap program.

Q 7:

Is there a fee if I decide to cancel?
