Natural gas is an important part of everyday life. So it's nice to know that you
can rely on North Shore Gas to keep your home
comfortable.
You can also count on us to provide the information you need to manage your energy costs.
A good way to start is by understanding the rates you see on your monthly natural gas bill.
How do I know which rate I am charged?
To find your rate, look at the top section of your bill under the service classification section. The image below shows a bill for a Rate 1 Heating Sales customer.
Am I a heating customer or non-heating customer
Heating customers are customers who use gas as their principal source of space heating. Non-heating customers are customers who do not use gas as their principal source of space heating. The rates for Heating Customers differ from those for Non-Heating Customers. If you have questions about the difference between the "Heating" and "Non-Heating" designations or would like to request an inspection to make sure your service is classified correctly, please call us at 866-556-6004.
Am I a sales customer or transportation customer?
"Sales customers" served under Rate 1 purchase natural gas directly from
North Shore Gas, which also delivers the
gas as a bundled service. "Transportation customers" served under Rate 1 purchase
gas from an alternate supplier through the Choices for You program, although
North Shore Gas is responsible for delivering
the gas.

North Shore Gas Energy Efficiency Program
Each month, your bill may include a charge
that pays for the costs related to energy efficiency and on-bill financing programs
mandated by Illinois Public Act 96-0033. The programs offer incentives for customers
to make energy-saving improvements to their homes.

not in any way affect charges for the gas you use.

state of Illinois to fund the Illinois Commerce Commission.
- State gas revenue tax: either 5 percent of current charges before
taxes or 2.4 cents per therm, whichever is lower.

Who is this rate for?
The natural gas rate for residential service is designed to serve:
- your single-family home, two-flat served by one meter, condominium, or
- your apartment if it has its own meter
If you live in an apartment, condominium or other building where three or more
units are served by one meter, the North Shore Gas rates for business applies.
Customers signed up for our supplier choice program can learn about their charges.

How reliable is the service this rate provides?
The Natural Gas Rate for Residential Service provides uninterrupted
service to your home, except in emergencies. This means gas is available to
you whenever you need it. The only exception — as with any gas
service — is when unexpected events occur such as a interruption due to
digging into a gas line. When this happens,
North Shore Gas responds immediately
to restore service as soon as possible.

How is the gas I use measured?
The amount of gas flowing through your meter is measured in "hundred
cubic feet" (CCF). But you are charged based on the average heat content
of the gas delivered to your home — or the number of therms you use.
One therm is equal to 100,000 British Thermal Units (BTUs). One BTU
represents the amount of heat needed to raise one pound of water one degree
Fahrenheit at sea level.
Your bill shows how much gas (CCF) you used for the past month and a
calculation that converts the amount of gas used (CCF) to reflect the heat
content of the gas (therms). The heat content of gas may vary.
North Shore Gas determines the heat
content of gas received from our supplier for the past month. The result is
shown on your monthly bill.
