Amendments for the AESO Connection Process

Important Dates

May 27, 2025 | Stakeholder Feedback due

March 5, 2025 | Narrated presentation posted

Purpose

To make required changes to the Tariff to align with the current AESO Connection Process, provide clarity where needed and enable a more efficient process. We will not be making significant changes to the AESO Connection Process as part of this engagement.

This engagement process will review the following ISO tariff(External link) components:

  • System Access Service (SAS) Agreements for Rate DTS and Rate STS
  • Construction Commitment Agreements (CCA) and Security paid to the TFOs
  • Payment in Lieu of Notice (PILON)
  • Overall layout and presentation of content in Sections 3, 5, and 6 of the ISO tariff

Throughout 2022 to 2024, we streamlined the Connection Process by developing the Cluster Assessment Process(External link) with robust stakeholder input.

Out of Scope

Although there will be overlap and interdependencies, the below topics/workstreams are out-of-scope and will be covered in other work streams:

  • Existing GUOC provisions, as well as design of the new Transmission Reinforcement Payment (TRP)
  • Ancillary Services cost allocation
  • Transmission cost allocation and contribution policy
  • Internal demand rates
