Conditions of Interruptible Service
Interruptible services are available only to the extent that Questar Gas
has available capacity and/or gas supply to provide this service without
impairing its ability to serve firm sales service customers. The service-interruption
process is discussed in the following section.
Interruptible customers must maintain standby
equipment and standby fuel to provide a substitute for gas service during
periods of interruption.
Interruptible customers will be required to
enter into a service agreement. Requirements for transportation customers,
such as gas measurement equipment, balancing and nominations, are discussed
in the Transportation Processes section.
Interruptible Sales Service Each year Questar Gas will offer an open season
for customers to request interruptible sales service under the I-2/IS-2
and I-3/IS-3 rate schedules. During this time, existing customers will
be notified of market-based price terms available for I-2/IS-2 and I-3/IS-3
interruptible sales service. Information concerning the open season is
available to any prospective customer, and notice of open season dates
will be posted at Questar Gas's offices in advance of each year's open
season.
Interruptible sales customers will be required
to pay the meter-based customer charge and will be subject to a minimum
yearly charge. Questar Gas may allow I-2/IS-2, I-3/IS-3 and I-4/IS-4 customers
to exceed their daily contract limits. Usage that exceeds the daily contract
limit will be charged at the I-4/IS-4 rate. Questar Gas reserves the right
to limit usage to the daily contract limit. If the customer is requested
to limit usage to its contract amount, any usage beyond that limit will
incur a penalty.
Customers installing new facilities in Questar
Gas's service area and requesting interruptible sales service may be served
as an I-4/IS-4 customer on a best-efforts basis. Questar Gas may require
these customers to wait until the next open season before offering I2/IS2
interruptible sales service.
I-2 I-2 is available on an annual contract basis
to customers who enter into a service agreement. Customers must maintain
the ability to interrupt natural gas service or have purchased firm standby
service under Questar Gas's F-3 rate schedule. Customers must have a load
factor of 15 percent or greater. Customers will forecast their monthly
and annual usage during the open season period. If the customer's actual
usage exceeds the monthly forecast, the additional usage wil be charged
at the I-4 rate. If the usage is less than the I-2 rate, a surcharge equal
to the difference between the I-2 rate and the I-4 rate will be charged
on volumes not consumed. Service is
subject to a minimum yearly charge and a meter-based customer charge.
Daily contract limit must not exceed 2,000 Dth/day. Minimum annual volume
is 7,000 Dth.
I-2 customers failing to renew their I-2 contract during the open season
will be served on I-4 rates after the termination date of the I-2 contract
unless other arrangements are made.
I-3
I-3 service was introduced and implemented in the Spring of 2002 for the
Industrial user with higher loads during the summer months verses the
winter months. Customers wishing to take advantage of lower prices during
the spring and summer months at a fixed rate, must use 70 percent of their
total annual sales volumes during the summer period and maintain an annual
15 percent load factor. This service has an open season similar to I-2,
however, it is conducted in late winter to early spring, with a contract
period of April 1st through October 31st. An estimated market price will
be offered for approximately one-week period. Depending on the amount
of interest by the industrial users, gas will be purchased according to
their daily or estimated daily load.
I-4 I-4 is available on an annual contract basis
to customers who apply during the open season and enter into a service
agreement. Customers must maintain the ability to interrupt natural gas
service or have purchased firm standby service under Questar Gas's F-3
rate schedule. Rate per dth used each month will be based on the
Market Index Price, adjusted for commodity cost fuel gas charges and transport
charges on an upstream pipeline and Questar Gas final prices will be posted
monthly on the Questar Gas web site, (www.questargas.com) within 5 working
days of the end of the month.
Customers must have a load factor of 15 percent or
greater. For these customers, the day of highest usage in the November
1 to March 31 period will be used in place of daily contract limit in
calculating the minimum bill. Service is subject to a minimum yearly charge
and a meter-based customer charge. Minimum annual volume is 7,000 Dth.

areas who meet the I-2 requirements listed above.
