Due to complex interdependencies discovered through engagement and taking into consideration stakeholder feedback, the engagement schedule has been adjusted as follows. We are also in the process of designing the TRP Base Rate engagement as discussed with stakeholders in April, and participation details will be shared in the coming weeks.

Note: These dates are tentative and being shared for stakeholder planning purposes.

Feb. 2, 2026

Thank you to everyone who has taken the time to share feedback throughout the TRP & Supply SAS engagement. Your insights have been invaluable and continue to play a central role in shaping the direction of this initiative.

We are now using perspectives received to inform and develop the final TRP design, specifically, refine key elements around the TRP methodology (how to determine the base rate and scalars), and how TRP should be applied.

We look forward to sharing the evolution of this work. The decisions made, including how your input influenced the final TRP design, will be communicated at our upcoming stakeholder session in April.

Thank you again for your continued engagement and collaboration.

Date Adjustment for the October Workshop | Oct. 8, 2025

With the Oct. 21-22 Ancillary Services Cost Allocation workshop being postponed, we will now host the Transmission Reinforcement Payment (TRP) & Amendments for the Connection Process Workshop on Oct. 22-23.

You have until Tuesday, Oct. 14 to submit or adjust your request to attend in-person, and will receive a confirmation of your attendance afterwards.

OTP & TRP Concurrent Engagements | April, 2025

The AESO has heard from stakeholders about how its approach to Optimal Transmission Planning (OTP) could include other elements that would inform the decision on whether to proceed with transmission development, like the payment of a Transmission Reinforcement Payment (TRP) by new generators. The AESO will engage and develop OTP and TRP concurrently to ensure that the signals and decisions driven by each set a transmission framework that supports Alberta’s affordability, reliability, and sustainability objectives. As part of the TRP engagement, the AESO will also engage on how this new transmission framework works with the Restructured Energy Market (REM) to provide siting signals for generations in a manner that recognizes incumbency and supports investability and economic efficiency.

For the TRP engagement, the AESO will propose and seek feedback on TRP starting points and options, as well as provide an opportunity for stakeholders to submit their TRP proposals.
