Northern Natural Gas

Firm Transportation (TF/TFX/GS-T)
As a firm shipper you can count on the delivery of gas when you need it on Northern's system. Northern's high level of reliability gives you the confidence you need to serve markets across the country. Contract quantities for firm transportation are generally expressed in terms of maximum daily quantity in Dth. This is the volume of gas that Northern is obligated to transport from the point(s) of receipt to the point(s) of delivery. Your firm contract term can be varied as well, from one day to multiple years, depending on your requirements.

Advantages of using firm transportation at maximum tariff rates: You can use all delivery or receipt points within the contract area (Field Area or Market Area) as alternate firm delivery or receipts points, subject to capacity availability.

Additional advantages of using firm transportation:

		Northern's pricing desk is available to competitively market Northern's capacity on a daily basis.
		Pooling points can be used to simplify the delivery or purchase of gas supplies.
		Volume in excess of the total firm maximum daily quantity is transported as interruptible overrun service.
		Term can vary, depending on your needs.
		Northern will provide marketing services to assist you in marketing your excess capacity.

Interruptible Transportation (TI)
Interruptible transportation is designed to give you a flexible alternative to our firm transportation service. This is a commodity-based service determined on the volume that actually flows; therefore, you pay only for the capacity you use. On an interruptible transportation contract, volume is transported, subject to interruption.

Advantages of adding interruptible service to your gas portfolio include:

		All point flexibility, subject to capacity availability, at maximum tariff rates.
		Pooling points can be utilized to simplify the delivery or purchase of gas supplies.
