July 3, 2025 - Binding Turnback and Binding New Capacity Open Seasons for NIT to TEP (NTT) Service and Empress to TEP (ETT) Service

Open Season Request Window Closes July 16, 2025, 4:00 p.m.

In an attempt to assist Customers in the capacity management of their NTT and ETT service, TGL is soliciting service bids to assist customers in securing their Alberta Supply gas transportation service as outlined below:

1. Requests for turnback of NTT and/or ETT capacity; and
2. Requests for new NTT capacity no earlier than November 1, 2025 for turnback or shedding and no earlier than April 1, 2029, for new NGTL capacity;
3. Requests for Conversion of Existing ETT to NTT; and
4. Request for new ETT capacity no earlier than November 1, 2025

TransGas may extend the deadline for the Binding Turnback and Binding New Capacity Open Season for NTT and ETT Service after TCPL Mainline announces the duration of their Open Season, provided it closes later than July 16, 2025.

TransGas is making available potential turnback of NTT and ETT capacity while also actively pursuing additional NTT and ETT capacity. With firm commitments, TGL may be able to convert customers from ETT to NTT using current NTT contract shedding, facilitate the permanent assignment of unwanted NTT or ETT contracts, and adjust additional requests for NTT or ETT service with interconnecting pipelines.

Please review the following information before completing and submitting your Request Form(s). There are four (4) different Request Forms available, each corresponding to a specific type of request. A separate form must be completed for each request. Please refer to Schedule A for examples.

1. Turnback of NTT and/or ETT Capacity

The turnback of a contract moves the expiry date to an earlier point in time.  In order to minimize the economic impacts of a turnback, TransGas will only facilitate a turnback if another customer is willing to take assignment of that existing contract. The section below includes information and instructions for completing 1) Request Form – Binding Turnback of NIT to TEP (NTT) or Empress to TEP (ETT) Capacity:

• Eligibility: Only long-term firm ETT and R1105 NTT Services are eligible for turnback to ensure rate neutrality.
• Existing Information: Enter existing information for the NTT or ETT contract including the contract number, volume and term for the existing or future dated contract.
• Volume: Customers may request turnback of all or a portion of the volume associated with active or future-dated NTT or ETT contracts. Customers must include the minimum and maximum volume requested for turnback. The maximum volume cannot exceed the existing contracted ETT or NTT volume.
• Effective Dates: Customers can request that the turnback be effective as of October 31 or March 31 of any year (as early as 2025) prior to their current NTT or ETT contract expiration date. Where possible, multiple preferred effective dates should be indicated in order of declining preference on the Request Form. If accepted, the effective date will be established as the new expiry date or the date when the contract volume is reduced. 

2. New NTT Capacity or Conversion of Existing ETT to NTT Capacity

NGTL has posted notice indicating that an Expansion Capacity Open Season is expected to take place from August to September 2025 for Firm Transportation – Delivery Group 1 Service (FT-D1) at the Empress and McNeil Border (FT-D Expansion Capacity - EGAT Open Season). The available capacity is expected to be up to 235,000 GJ/d with an estimated effective date of April 1, 2029.

TransGas will use the following to determine if new NTT capacity is required:

1. If requests for new NTT capacity can be satisfied by turnback NTT contracts
2. If Customer requests to convert existing or future dated ETT to NTT, contracts could be satisfied by turnback NTT contracts

The section below includes information and instructions for completing 2) Request Form – Binding New Capacity Open Season for NIT to TEP Service:

• Effective Date: Will be either the accepted shed date of another customer’s NTT contract as early as November 1, 2025 or the effective date for expansion capacity, estimated as April 1, 2029. Please enter a preferred effective date into the Request Form so that TransGas can consider it as part of the review process. Multiple preferred effective dates can be indicated in order of declining preference on the request form. The effective date will be established based on the availability of NTT. Please confirm if April 1, 2029 is acceptable if an earlier date is not available.
• Term Lengths: NGTL requires a minimum initial term of fifteen (15) years for Customers bidding on the upcoming Expansion Capacity Open Season. NGTL awards capacity starting with the highest term bid, working through the list until all expansion capacity has been awarded. Therefore, Customers with longer term bids have a higher likelihood of successfully obtaining new capacity. Please enter a maximum term into the Request Form.
• Volume: Customers must include a minimum and maximum requested volume. The maximum volume cannot exceed 235,000 GJ/d. The minimum volume indicates the smallest amount of acceptable new capacity that the Customer will accept; if any volume, up to the requested maximum is acceptable, identify the minimum volume as zero (0 GJ/day).
• ETT as an alternative to NTT: Customers must identify if they are willing to take ETT service if their NTT bid is unsuccessful. In these cases, an additional condition is included in the ETT contract reserving the right for TransGas to convert the ETT to NTT service in the future.
• Meter Codes: Please include the meter code(s), or planned future facility, with the corresponding volume that may be associated with the requested NTT service. Note only this section on the form is non-binding and will assist TransGas in facility planning.

The section below includes information and instructions for completing 3) Request Form - Binding Open Season for Conversion of Existing or Future-Dated ETT to NTT:

• Existing Information: Enter existing information for the ETT contract including the contract number, volume and term for the existing or future dated contract.
• Effective Date: Will be either the accepted shed date of another customer’s NTT contract as early as November 1, 2025 or the effective date for expansion capacity, estimated as April 1, 2029. Please enter a preferred effective date into the Request Form so that TransGas can consider it as part of the review process. Multiple preferred effective dates can be indicated in order of declining preference on the request form. The effective date will be established based on the availability of NTT. Please confirm if April 1, 2029 is acceptable if an earlier date is not available.
• Term Lengths: NGTL requires a minimum initial term of fifteen (15) years for Customers bidding on the upcoming Expansion Capacity Open Season. NGTL awards capacity starting with the highest term bid, working through the list until all expansion capacity has been awarded. Therefore, Customers with longer term bids have a higher likelihood of successfully obtaining new capacity. Please enter a maximum term into the Request Form which may require a customer to select a longer term than the existing ETT contract.
• Volume: Customers may request conversion of all or a portion of the volume associated with active or future-dated ETT contracts. Customers must include the minimum and maximum volume requested for conversion. The maximum volume cannot exceed the volume of the ETT contract. The minimum volume indicates the smallest amount of acceptable capacity; if any volume up to the requested maximum is acceptable, set the minimum to zero (0 GJ/day).
• Meter Codes: Please include the meter code(s), or planned future facility, with the corresponding volume that may be associated with the requested NTT service. Note only this section on the form is non-binding and will assist TransGas in facility planning.

The section below includes additional information for consideration:

• Cost of Service: The cost for this service is the R11.0 Long Term Firm Receipt Transportation plus Additional Cost Recovery | TransGas (ACR); current TransGas rates are subject to change.
• Shed Notice: Successful NTT bids will be subject to a 27-month shed deadline and have renewal rights. To continue to maintain renewal rights, the renewed term must be three (3) years or greater.
• Renewal Rights: NTT service that is eligible for renewal rights, will automatically renew for three (3) years unless a customer provides written notice to terminate at least 27 months before the current term expires. Any NTT contracts awarded with less than a three (3) year duration will have No Renewal Rights (NRR) and based on term, may or may not be successfully awarded.
• Additional Considerations:
  • Bids are irrevocable and immediately binding upon the close of this Binding Open Season.
  • If the ETT capacity can be fully converted to NTT, TransGas will terminate the ETT contract and execute the NTT contract for the term requested. If a portion of the contract is converted, the ETT contract will be reduced by the amount converted and a new NTT contract for that amount will be executed.
  • TransGas' in-service dates for NTT capacity depend on the readiness of associated NGTL and TCPL Mainline facilities. In-service dates may be delayed due to several reasons including, but not limited to, regulatory approvals, construction (interconnecting pipeline or TransGas facilities), Force Majeure events, or other factors beyond TransGas' reasonable control. NTT offers are contingent on TransGas receiving confirmation from interconnecting pipelines that they can meet transportation schedules with the full contract demand quantity before NTT service begins. TransGas must find the terms and conditions acceptable at its sole discretion.
  • TransGas does not guarantee it will, nor is it obligated to, satisfy all requests for new capacity, or that requested capacity will align with the requested start date(s).
  • A successful bid will only guarantee receipt capacity for gas to a Customer’s TEP account. For a Customer to have a guarantee that gas is available at a specific Point of Delivery, the Customer must also have an approved delivery contract.
  • Queue deposit is not required.

3. New ETT Capacity

To provide incremental import receipt capacity and respond to the potential TCPL Mainline Capacity Open Season, TransGas is soliciting requests for new ETT capacity. The TCPL Mainline Binding Open Season is anticipated in July closing in August. The section below includes information and instructions for completing 4) Request Form - Binding Open Season for Empress to TEP Service:

• Effective Date: Requests for new ETT capacity will commence no earlier than November 1, 2025, and will be dependent on the availability for Mainline Capacity as identified in the TCPL Mainline Open Season. The customer must specify their preferred start date on the Request Form. Multiple preferred effective dates can be indicated in order of declining preference on the request form. The effective date will be established based on the availability of NTT.
• Term Lengths: Capacity on the TCPL Mainline is prioritized based on toll x term (across all the TCPL Mainline delivery areas), followed by date of commencement if a tie occurs (earlier preferred). Since TransGas pays the lowest tolls on the Mainline, it is typical that longer terms are required to be successful. The longer the term, the higher likelihood that TransGas can secure capacity through the TCPL Mainline Open Season. Customers must state their term length in the Request Form.
• Volume: Customers must include a minimum and maximum requested volume. The minimum volume indicates the smallest amount of acceptable capacity; if any volume up to the requested maximum is acceptable, set the minimum to zero (0 GJ/day).
• Meter Codes: Please include the meter code(s), or planned future facility, with the corresponding volume that may be associated with the requested NTT service. Note only this section on the form is non-binding and will assist TransGas in facility planning.

The section below includes additional information for consideration:

• Cost of Service: The cost for this service is the R11.0 Long Term Firm Receipt Transportation, current TransGas rates are available on the TransGas website and are subject to change.
• Shed Notice: Successful ETT bids will be subject to a 27-month shed deadline and have renewal rights. To continue to maintain renewal rights, the renewed term must be three (3) years or greater.
• Renewal Rights: ETT service that is eligible for renewal rights, will automatically renew for three (3) years unless a customer provides written notice to terminate at least 27 months before the current term expires. Any ETT contracts awarded with less than a three (3) year duration will have No Renewal Rights (NRR) and based on term, may or may not be successfully awarded.
• Future Conversion from ETT to NTT: TransGas has the discretion to convert ETT service to NTT on the renewal date of each year, or prior to the renewal date if mutually agreed and NTT service is available.
• Customers holding ETT Service will need to bid on future NTT service offerings if interested in converting ETT to NTT service; ETT service will not be treated as a queue for future NTT service offerings.
• Additional Considerations:
  • Bids are irrevocable and immediately binding upon the close of this Binding Open Season.
  • The available TCPL Mainline Capacity depends on TransGas's takeoff capacity from the Mainline.
  • TransGas' in-service dates for ETT capacity depend on the readiness of associated NGTL and TCPL Mainline facilities. In-service dates may be delayed due to several reasons including, but not limited to, regulatory approvals, construction (interconnecting pipeline or TransGas facilities), Force Majeure events, or other factors beyond TransGas' reasonable control.
  • ETT service offering has the same priority of service as NTT Service.
  • TransGas does not guarantee it will, nor is it obligated to, satisfy all requests for new capacity, or that requested capacity will align with the requested start date(s).
  • A successful bid will only guarantee receipt capacity for gas to a Customer’s TEP account. For a Customer to have a guarantee that gas is available at a specific Point of Delivery, the Customer must also have an approved delivery contract.
  • Queue deposit is not required.

Open Season Process

1. Turnback, new capacity, or conversion requests must be submitted by July 16, 2025 at 4:00 p.m. Saskatchewan time. At that time, all requests become irrevocable and binding on the Customer until ten (10) days past the close of the anticipated NGTL Expansion Capacity Open Season in September. TGL is not obligated to accept any request for turnback or new capacity. Accepted requests may use any of the indicated effective dates and any volume between the minimum and maximum, inclusive.
2. Upon receipt, all bids will be evaluated and TransGas will package as needed at TransGas’ sole discretion in response to the potential NGTL Expansion Capacity and TCPL Mainline Capacity Open Season’s to avoid adversely impacting TransGas’ System or Customers. These requests are binding on TransGas only if, and when, TransGas can secure NGTL and/or TCPL Mainline contracts. Additional conditions will be outlined in the contract.
3. The requests received will be evaluated and awarded based on the following:
   1. Capacity contingent on the same term may be prorated depending on the amount of capacity available. If a Customer’s prorated allocation is less than their minimum request, that allocation will be zero.
   2. If total bids exceed current TCPL Mainline takeoff capacity on the TransGas System, TransGas reserves the right to delay the start-date of the NTT and/or ETT service, or prorate the NTT and/or ETT service, until interconnect capacity is expanded to accommodate the requested demand.
4. Future Binding NTT and ETT Open Seasons may be offered at TransGas’ discretion and may be contingent on the number of requests remaining, and conditions in the primary and secondary market.
5. Fulfillment of binding requests is not guaranteed. Once the binding term is complete, or a new NTT or ETT Binding Open Season is held, all unfulfilled requests will be terminated.
6. New capacity acquired through this Open Season may have the same priority of service as existing Firm NTT and ETT capacity when the contract commences. Since additional capacity is acquired through a future NGTL and TCPL Mainline Open Season, additional conditions may be required to align with NGTL and TCPL Mainline and would be communicated at that time.
7. TransGas shall notify Customers with initially successful requests for ETT service no later than ten (10) business days after TCPL Mainline awards the contract(s) through their Open Season. TransGas shall notify Customers with initially successful requests for NTT service no later than ten (10) business days after NGTL awards the contract(s) through their anticipated NGTL Expansion Capacity Open Season.
8. Once acquired, TGL will enter the new or amended contract terms into MyTransGas on the Customer’s behalf.

Requests are to be submitted via e-mail to TGL at the following email addresses by July 16, 2025 at 4:00 Saskatchewan time.
