How reliable is my natural gas service?
Commercial and Industrial Firm Natural Gas Service provides uninterrupted service
for your operation, 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 severe storm or a contractor digging into a gas
line) that make it impossible to deliver gas to you. When this happens, WPS responds
immediately to restore service.

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
— or the number of therms used. 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) your business 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. WPS determines the
heat content of the gas received from our supplier during the 30 days preceding your
last meter reading date. The result is shown on your monthly bill.

What charges are involved?
Each month your bill for gas service includes:
- Distribution Charge - covering the cost of delivering gas to your farm on
WPS's system. This
charge varies with the amount of gas you use each month. Your bill shows the number
of gas therms used multiplied by this cost per therm.
- Gas Cost - covering the estimated cost of gas and all related costs for
ensuring a reliable gas supply for our customers. It also includes
WPS's contract costs for securing:
- Adequate pipeline capacity to transport gas to this service area, and
- Adequate storage space for gas until it's needed.
- The Michigan Public Service Commission approves estimated gas costs. At the end
of the year, the commission compares WPS's actual
gas costs with the revenue collected from customers. The commission determines if too
much or too little was collected and considers this information as it sets gas costs
that WPS may charge for the next year.
- WPS's annual estimated costs are spread out
evenly over 12 months and listed as the Gas Cost on your bill. This charge varies with
the amount of gas you use. You pay $0.45 per therm for the gas you use.
- Fixed Charge - a charge that doesn't vary with the amount of electricity
you use. The Fixed Charge covers the cost of providing safe, reliable electric service.
For example, it includes the cost of WPS
owning, maintaining and operating equipment that generates and delivers electricity to your
farm, as well as the costs of providing customer service. The Fixed Charge is the minimum
amount you will be billed each month.

* WPS's existing and new
customers qualify for these rates if they are not subject to the incremental pricing
provision of the Natural Gas Policy Act of 1978.
** If your seasonal facility is used during the summer months,
you'll be billed for gas service May through Oct. If your seasonal facility is used
during the winter months, you'll be billed for gas service Nov. through Apr. Your
gas service may remain connected all year. Any incidental gas use during the "off-season"
will be included on your first bill of the following season. If substantial use of gas is
recorded during the off-season, WPS will send you a
bill during the off-season.
Several factors can influence your monthly gas use. Major factors
that can be measured by WPS are summarized in the
lower left-hand corner of your monthly bill.
