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.
