Natural gas rates

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.

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.
