Nicor Gas History

Nicor Gas' roots go back to local Ottawa bankers and businessmen who formed the Ottawa Gas Light and Coke Company in 1855. The company converted coal into coke for iron making and sold the flammable gas waste product to be used for lighting and cooking. Because some the company's directors supported Abraham Lincoln's runs for the U.S. Senate, the company distinguished itself by providing gas lanterns to light the first Lincoln-Douglas debate that took place in Ottawa on Aug. 21, 1858. Unlike the rapid mergers and consolidations that expanded Chicago's gas and electric utilities at the time, Ottawa Gas Light and Coke Company remained independent and locally owned following the Civil War and stayed so through 1909.

Beginning in 1910, Ottawa Gas Light and Coke Company and some 23 other utility and trolley railway companies were taken over by Illinois Valley Gas and Electric Company. This utility holding company and 38 other small suburban utilities were then taken over a year later by Samuel Insull's Public Service Company of Northern Illinois. Though Insull not only got richer, his power-grab helped develop suburban and rural electrification and gas service in northern Illinois outside Chicago. But in 1929, Insull's massive Middle West Utilities empire went bust. As a result, the Public Utility Holding Company Act of 1935 gave the SEC power to break up and reorganize the Insull's troubled utilities in northern Illinois.

Under SEC approval in 1937, Commonwealth Edison (Com-Ed) came to control northern Illinois' three major gas utilities. In 1950, Com-Ed merged two other ex-Insull companies, Illinois Northern Utilities Company and Western United Gas & Electric Company, into the Public Service Company of Northern Illinois. In 1953, Public Service merged into Com-Ed. The following year, Com-Ed reorganized; it spun off its gas businesses and formed the Northern Illinois Gas (NiGas) Company to run it. Thereafter, Com-Ed and NiGas formerly separated.

Through the 1960s, NiGas expanded its business by acquiring local gas utilities, increasing its gas underground storage capabilities, and then briefly diversified into non-utility investments. When deregulation started in Illinois, NiGas reorganized to become Nicor Gas. These initial years were rocky and controversial for Nicor, leaving it somewhat weakened. In 2011, Atlanta-based AGL Resources bought Nicor Gas, a move that gave AGL control over two very large metropolitan gas distribution markets. In 2016, AGL Resources merged with Southern Company, creating a utility with the 2nd largest customer base of approximately 9 million customers.

Now, as a subsidiary of Southern Company, Nicor Gas serves more than 2.2 million customers in a service territory that encompasses most of the northern third of Illinois, excluding Chicago. Nicor believes that part of their corporate responsibility is to give back to the communities they serve. Their philanthropic focus includes providing bill payment assistance, helping with food insecurity, protecting the environment, and enabling economic opportunity through education, job training and capital investment.

A public utility may not deny, cancel, or nonrenew utility service solely on the basis of credit information of prospective or existing customers. However, Illinois utility companies may deny your application for service if you owe them money for the same type of service at the same address or a different address.

Will I Need to Pay a Deposit?

In Illinois, no utility can require any new residential customer to pay a security deposit as a condition of receiving utility service. However, the utility can require a deposit if ONE of the following applies:

  • Nicor's meter was tampered with at your previous service.
  • Your previous Nicor service was disconnected for non-payment, and you did not pay the final bill.
  • If you are already a customer and have 4 late payments in the past 12 months.
  • You are applying for new service for an address where the former customer was disconnected for non-payment and they still reside at the same address.
  • Your credit score is below a predetermined minimum, you have no credit history, or you have filed for bankruptcy.

If you must pay a deposit -- Nicor Gas must notify you in writing no later than 45 days after your application for service is approved. IL law states that deposits cannot be greater than an estimated two months usage.

Customers don't need to pay the deposit all at once. You can rquest the utility to divide your security deposit into at least three installments. Nicor Gas can hold deposits for residential service for 12 months. If the customer pays their bill in full and on time for 12 consecutive months, the utility will refund the deposit plus interest.

Understand Nicor Gas Delivery and Supply Charges

In Illinois, residential customers pay for both the cost to deliver their gas as well as for the amount of gas supply that they use.

  • Delivery Charges are charges (tariffs) for the cost of sending gas to your home via Nicor Gas's gas lines. The charges cover the Nicor Gas local infrastructure operating costs, maintenance, and ensures them a profit. Other usage-based charges are small costs from riders to fund projects, cover fees, etc. Nicor Gas's delivery charges must be approved by the Illinois Public Service Commission (ICC). All Nicor Gas customers pay the same ICC-approved Delivery rates no matter who supplies their energy.

  • Supply Charges represent the price for the amount of gas that you use. Northern Illinois customers can choose to get their supply from Nicor Gas at its "Price to Compare" (PTC) supply rate. However, because of Illinois's Energy Choice program, customers are also free to choose energy from competitive alternative gas supply (AGS) companies.

  • What Are Nicor Gas PTC Charges?

    When deregulation began in Illinois, all utilities that wanted to participate in consumer choice had to limit their business to natural gas delivery. However, the Illinois Commerce Commission requires these utilities to provide gas supply at a default rate to customers in their service territory who don't shop for an alternate gas supplier.

    As a result, these utilities must purchase their gas supply for the default rate from natural gas companies on the wholesale market. Most gas utilities in the U.S. north buy their winter supply in summer and keep it stored underground until it's needed. They also purchase gas on the market year 'round to supplement their stored supplies.

    The ICC oversees Nicor Gas default rates. Illinois gas utilities use a regulatory mechanism called the Purchased Gas Adjustment (PGA) to compute the monthly gas supply price for their customers. Under the PGA mechanism, the price that default-service customers pay per therm of gas that they consume can change monthly. Also, under Illinois law, utilities can't make a profit from this per-therm charge. This is because the per-therm charge is strictly a pass-through amount for the price of gas that utilities pay on the market.

    The PGA includes the anticipated cost of gas for the month as well as adjustments from prior periods that are used to make up for over or under charges. The ICC does not approve these rates in advance but rather reviews them annually. It can then order gas utilities to pay refunds to customers if the utilities weren't using sound business practices to buy gas at a reasonable cost.

    Nicor Gas customers can use the PGA default rate as their "Price to Compare"(PTC) when they shop for plans offered by alternative gas suppliers.

    Market prices for natural gas change constantly. This is due to over all gas demand, available interstate pipeline capacity, and gas production. As a result, the Nicor Gas default rate changes month-to-month. Most noticeable is how much the default supply charge can vary seasonally; low some months, higher the next. Consequently when market prices are higher, customers' bills could be correspondingly higher.

    Like most northern U.S. natural gas utilities, Nicor Gas buys most of its winter gas supply in the summer and stores it until it's needed. While summer gas prices are usually still cheaper, the increasing use of natural gas to generate electricity for summer air conditioning is having an increased affect on prices.

    All this means that with the default rate, you can never be too sure what you'll pay from one month to the next.

    Nicor Gas Current PTC Residential Rates:

    $0.340 per therm, expires 8/31/2024

    How Much Do Nicor Gas Supply Charges Cost?

    Nicor Gas' deliver charges are made up of a monthly customer charge $17.96 and a usage-amount distribution charge ($0.0838 per therm).

    Let's plug all these numbers into a practical estimate...

    The US Energy Information Agency reports that in 2019, Illinois' residential customers used an average of about 87 therms each month.

    Therefore, an average, non-winter, residential PTC bill from Nicor Gas roughly breaks down like this:

    Rate per 87 Therms Used Total Monthly Customer Charges Total
    PTC Supply Rate
    (excluding other surcharges)
    0.340 cents 0 $29.58
    Monthly Distribution Charges
    (excluding riders and other surcharges)
    $0.0838 per therm (distribution) $17.96 $25.25
    Total Bill $54.83

    Understand Illinois Energy Choice

    Illinois natural gas consumers are free to choose to buy gas from Alternate Gas Suppliers (AGS). These alternative suppliers shop deals with different gas suppliers on the wholesale market to offer competitive rates. As such, their rates are not controlled by ICC. This way, AGS are able to offer competitively priced fixed rate plans for a variety of term lengths.

    Though it can seem confusing, shopping gas plans is an easy process. The trick is finding the one that meets your needs.

    That's why retail energy suppliers in Illinois offer two types of plans:

  • Fixed Rates have their price rate set for the same price over the term of the contract. Customers can count on stable energy rates on plans lasting from 3 to 36 months. Many fixed rate plans used to come with early cancellation fees for breaking a contract early. However, on January 1, 2020, the state gave residential and small commercial retail customers the right to terminate their contracts with alternative gas suppliers at any time without any termination fees or penalties. This means you can shop for a new plan any time!

  • Variable Rates Want to avoid getting tied to an gas plan for months or years? Then choose a variable plan. Variable plan rates on these contracts can change from month to month depending on the price of the gas supply. But while there's no contract, there's nothing to prevent your rate from going up one month or down the next. However, these plans also don't have any termination fees and this allows customers the flexibility to shop for new rates and switch to better deals without paying any penalty.

  • Your Energy Usage and Your Nicor Gas Bill

    Your Nicor Gas usage affects your energy bills.

    Your energy usage habits are unique, but as any Illinois native will tell you, Illinois winters are usually long and often bitterly cold while summers can be hot, hazy, and humid. So, your biggest energy usage will usually follow the weather. However, remember all those other domestic activities, like cooking and cleaning, will also add to your monthly bill.

    As of 2019, about 77 % of homes in the state relied on gas for heat. In recent years, however, national home building trends increasingly construct homes that rely on electric heating systems, such as Geothermal heat pumps or electric radiant heat systems.

    Most midwest households rely on air conditioning during the summer months. But while air conditioning use only makes up 2% of a home's total annual energy usage, Illinois residents spend on average 5% of their annual energy costs on air conditioning. About 25% of Illinois households have window or wall-mounted AC systems but about 65% have central AC.

    The remainder of energy use goes to water heating, refrigeration, lighting, electronics, clothes dryers, cooking, and small appliances.

    Want to learn more about your home energy usage? Nicor Gas customers can track 24 months of their home's natural gas usage plus other relevant information by logging on to your Nicor Gas account.

    The most effective way to cut your energy bills is to reduce your usage by sealing your doors and windows against winter and summer drafts. Adding insulation to your attic, sealing and insulating your basement, and purchasing a programmable or smart thermostat can also improve your home's energy efficiency and help cut your natural gas bills. Your utility company can provide a wealth of resources and may offer programs to help you improve your home's energy performance.
