TRANSPORTATION SERVICES 

 

No-Notice Transportation Service (NNS)

Small General Transportation Service (SGT)   

Texas Gas provides a no‑notice service that reflects the unique operational capabilities of Texas Gas' pipeline system, including significant reliance on storage as a surrogate for transmission capacity.  The contract demands, designed to meet the wide-ranging seasonal requirements of Texas Gas’ customers, consist of both daily nominated pipeline capacity and daily swing storage capacity, which allows Texas Gas to fully utilize the system’s operational capabilities.  This rate schedule also provides firm hourly rights equal to 1/16th of the contract demand to the Customer’s primary delivery point.

 

Texas Gas’ Customers who have  winter no notice contract demand less than 7,500 MMBtu per day; whose total firm contract demands under all firm rate schedules does not exceed 10,000 MMBtu per day; and who were sales customers on May 18, 1992, are eligible for Small General Transportation Service (SGT). Texas Gas’ SGT Rate Schedule has a one-part commodity rate in lieu of a two-part demand rate structure and, as a result, there are restrictions on the use of other transportation services by SGT customers to meet their city gate needs.

 

NNS and SGT, along with SNS, FT and STF, provide the highest level of transportation priority on Texas Gas’ system.

 

Tariff rates for NNS and SGT are on Sheets 20 and 21 of Texas Gas’ FERC Gas Tariff.

 

Summer No-Notice Transportation Service (SNS)

SNS service combines firm pipeline capacity with summer off-peak storage capacity to handle swings in deliveries as an unnominated, no-notice service and provides firm variable hourly flow rights of 1/16th of the Customer’s contract demand to their primary delivery point.  The service allows for seasonal storage up to three times the contract demand providing additional flexibility.  This no-notice service is only available on a firm basis in the Summer Season (April through October).

 

SNS service provides for daily and hourly overruns.  The hourly overrun feature is a service feature not available under any of Texas Gas’ other rate schedules.

 

Tariff rates for SNS are on Sheets 22 and 23 of Texas Gas’ FERC Gas Tariff.

 

Firm Transporation Service (FT)

Transportation under the FT Rate Schedule provides customers with nominated firm transportation service from designated receipt points to designated delivery points.  The firm transportation contract demand must be a daily transportation quantity which is the same for each day of the contract term, which term must be for at least 12 consecutive months of service.  FT Service provides customers with firm hourly deliveries up to 1/24th of their firm transportation contract demand.  

 

FT, along with NNS, SGT, SNS, and STF provide the highest level of transportation priority on Texas Gas’ system.

 

Tariff rates for FT are on Sheets 24 - 26 of Texas Gas’ FERC Gas Tariff.

Short Term Firm Transportation Service (STF)

STF is very similar to Texas Gas’ FT Rate Schedule except that STF shall be for a term of less than 12 consecutive months, or the daily contract demand may vary by month or season over the term of an agreement one year or longer in length.  The seasonal nature of this service is reflected in its peak (winter) and off-peak (summer) rates.

 

STF priority is the same as FT.

 

Tariff rates for STF are on Sheet 28 of Texas Gas’ FERC Gas Tariff.

 

Interruptible Transportation Service (IT)

IT service is subject to interruption both at the receipt and delivery points.  Tariff IT rates, like the STF rates, are seasonal in design for winter and summer.

 

IT’s scheduling priority, similar to authorized overruns of the firm services, is based on an economic queue.  

 

Tariff rates for IT are on Sheets 29 and 30 of Texas Gas’ FERC Gas Tariff.

 

Enhanced Firm Transportation Service (EFT)

Texas Gas’ enhanced firm transportation service (EFT) is available to Texas Gas customers who have executed a transportation service agreement for firm transportation service under the FT or STF Rate Schedule. EFT service permits customers to receive deliveries of gas at their primary delivery point at a variable hourly flow rate up to one-sixteenth (1/16th) of their contract demand except during times when Texas Gas has given notice to customers that EFT service is unavailable. Customers requesting EFT service must execute an EFT addendum to their current FT transportation agreement for quantities up to the FT contract demand. 

 

Tariff rates for EFT are on Sheet 27 of Texas Gas’ FERC Gas Tariff.

Parking and Loan Service (PAL)

The Parking and Loan rate schedule is available for the interruptible parking and loan of natural gas by Texas Gas for Customers.  The Parking and Loan Service is currently offered at Texas Gas’ Zone SL and Zone 1 pooling points. 

 

Parking and Loan Services are interruptible services and have a service priority below Texas Gas’ other firm and interruptible services. Customer may either borrow (loan) or bank (park) gas on Texas Gas’ system under the PAL Rate Schedule up to a daily and seasonal quantity specified in their PAL Service Agreements.  A separate PAL agreement is needed for Parks and Loans. PAL service is provided for a minimum term of one (1) day and a maximum term of thirty-one (31) days, as specified in the PAL service agreement.  The maximum period of the PAL service agreement may be extended by Texas Gas, at Texas Gas’ sole discretion.

 

Tariff rates for PAL are on Sheet 34 of Texas Gas’ FERC Gas Tariff.

 

Hourly Overrun Transportation Service (HOT)

This rate schedule is available to any Delivery Point Operator that desires deliveries from Texas Gas in excess of the hourly flow rights under all transportation service agreements delivering quantities to the subject delivery point.

 

Hourly overrun service is completely interruptible at any time and is the lowest priority of service offered by Texas Gas.

 

Hourly overrun service shall not increase any Customer’s daily deliveries, but shall merely provide for additional hourly flexibility in delivery of those daily quantities.

 

Tariff rates for HOT are on Sheet 32 of Texas Gas’ FERC Gas Tariff.

 

Transportation Aggregation Pooling Service (TAPS)

Texas Gas’ Rate Schedule TAPS allows parties the ability to aggre­gate or pool its supply portfolio.

 

 

All receipt points in a particular zone are eligible to be transported to the logical or "paper" pooling pont in that zone.  A party with a TAPS agreement nominates gas from any receipt pont in the zone in which they are pooling supply to be delivered to the logical pooling point.  There is no transportation rate or fuel retained under the TAPS agreement.  The TAPS market(s) then nominates gas receipts from the pooling point to be redelivered under their transportation agreements. Transportation customers nominating gas receipts from a pool will be allocated a volume equal to their confirmed nomination thereby keeping all imbalances between Texas Gas and the pooling party.  Texas Gas currently has Pooling Points established in its Rate Zones Zone SL and 1 for both firm and interruptible services.

STORAGE SERVICES 

 

Texas Gas’ storage complex is located in the heart of its market area.  The complex consists of 9 storage fields, with total working gas capacity of 84.3 Bcf and the ability to withdraw 2.4 Bcf/d.  Texas Gas uses most of this storage to provide the operational flexibility of the no-notice customers under Rate Schedules NNS and SGT, but also offers storage capacity on a firm and interruptible basis as stand-alone services.  Transportation to and from the storage complex must be contracted for separately.

 

Firm Storage Service (FSS)

Firm Storage Service (FSS) provides for the firm receipt and injection of Customer's gas into storage during the Summer Season and the subsequent firm withdrawal and delivery of gas during the Winter Season.  FSS is a nominated service that requires the Customer to nominate quantities to be injected into or withdrawn from storage.  Summer withdrawals and winter injections are also permitted on an interruptible basis.

 

Texas Gas permits transfers, in whole or part, of the gas in storage inventory provided both parties to the transfer: 1) have executed service agreements under Rate Schedule ISS, FSS, or NNS; 2) have executed transportation service agreements which will permit the delivery of the gas, and 3) such transfer does not result in either Customer exceeding its Maximum Seasonal Quantity.

 

An FSS Customer also needs a transportation agreement in place to transport gas to storage for injection and also to redeliver to a Texas Gas delivery point.  The agreements for delivery to and from storage may be interruptible.  Charges related to the transportation of gas to and from storage are billed pursuant to the transportation agreement.

 

Tariff rates for FSS are on Sheet 33 of Texas Gas’ FERC Gas Tariff.

 

Interruptible Storage Service (ISS)

 Interruptible Storage Service (ISS) provides for the interruptible receipt and injection of Customer's gas into storage during the Summer Season and the subsequent interruptible withdrawal and delivery of gas during the Winter Season.  Summer withdrawals and winter injections are also permitted on an interruptible basis.  ISS is a nominated service in which Customers nominate quantities to be injected into or withdrawn from storage. 

 

ISS service is subject to Texas Gas satisfying its firm service obligations under its NNS, SGT and FSS rate schedules to otherwise ensure system operational integrity.

 

Texas Gas permits ISS Customers to transfer, in whole or part, gas in storage provided both Customers: 1) have executed service agreements under Rate Schedule ISS, FSS, or NNS; 2) have executed transportation service agreements which will permit the ultimate redelivery of the gas to a market; and 3) such transfer does not result in either Customer exceeding its Maximum Seasonal Quantity.

 

An ISS Customer also needs a transportation agreement in place to transport gas to storage for injection and also to redeliver gas to a Texas Gas delivery point.  Charges related to the transportation of gas to and from storage are billed pursuant to the transportation agreement.

 

Tariff rates for ISS are on Sheet 33 of Texas Gas’ FERC Gas Tariff.
