Bidding and Allocation Procedure for the Open Season:

The Open Season will commence on Thursday, June 18, 2026 at 10:00am Mountain Time (“MT”).

Bids are due Friday, August 7, 2026 before 10:00 a.m. MT.

All parties seeking to bid for this available service must complete the FT‑D Existing Capacity / FT-D Expansion Capacity Open Season Bid Form (page 30 of Appendix A).

A completed and executed FT‑D Existing Capacity / FT‑D Expansion Capacity Open Season Bid Form must be sent by email to ab_ft_openseason@tcenergy.com prior to the deadline shown above.

Prospective customers should submit bids that specify one of the three above listed Service Commencement Dates for the Available Capacity. Prospective customers may submit more than one bid. All bids are binding. No bid shall exceed the stated Available Capacity associated with the requested Service Commencement Date.

As per Appendix A to the NGTL Tariff, NGTL will evaluate all bids on a tranche-by-tranche basis, solely based on the requested term length specified in the FT-D Existing Capacity / FT-D Expansion Capacity Open Season Bid Form. Where a bid is not awarded, or is only partially awarded, within a specified tranche, the unawarded portion of such bid will be carried forward and considered as a bid for Available Capacity in the next tranche for the same requested term length. This bid allocation may result in a bid being awarded in more than one tranche. By submitting a bid, the prospective customer agrees to this bid allocation methodology. NGTL will only consider a contract term of 15 years or more to align with other recent Expansion Capacity contract term lengths (consisting of 5 years Primary Term with the remaining term to be Secondary Term). The requested Service Termination Date entered in the FT-D Existing Capacity / FT-D Expansion Capacity Open Season Bid Form shall be the last Day in a month.

Prospective customers will be required to meet the deposit requirement outlined in Appendix A to the NGTL Tariff.

Awarding Expansion Capacity:

The successful bidders in the Open Season will be required to execute a Project and Expenditure Authorization (“PEA”), a Service Agreement (if required) and Schedule of Service commensurate with the awarded targeted service commencement date, Contract Demand and term. NGTL will provide Notice to successful bidders in accordance with Appendix A to the NGTL Tariff.

Upon receipt of the PEA, Service Agreement (if required) and Schedule of Service, successful bidders will have 5 Banking Days to return executed documents and 10 Banking Days to satisfy Financial Assurance requirements. The amount of Financial Assurance that NGTL may request from the successful bidder is an amount payable to NGTL under the Schedule of Service of 70 days plus one month for each year of term, up to 12 months total.

All capitalized terms not defined herein have the meaning ascribed to them in the NGTL Tariff.
