System Access Business Practice
As part of its responsibilities the AESO is required to provide access to the transmission system. To assist market participants, the AESO has developed a document which provides information regarding important AESO system access service practices that are applied when planning the transmission system and connecting generation and load. The practices outlined in the document will be utilized by the AESO within the Connection Process to promote timely new connections and provide reasonable system access service to all market participants.
Once requirements have been met projects will be listed on the Connection Queue in addition to the Project List. Gate completion requirements for Gate 2 differ depending on the type of project:
In addition to the information provided in the Project List, the Connection Queue will provide the Gate 2 completion date and the current stage for each project listed.
Projects will be listed in the Connection Queue based on the date of Gate 2 completion.
Behind the Fence projects
BTF projects will be listed in the Connection Queue once they have met the requirements to complete Gate 2 of the Behind the Fence Process.

Contract Capacity Change Requests
Existing Contract Capacity Change Requests will be listed in the Connection Queue once a preliminary study has been completed at which time they will be considered to have met the requirements to complete Gate 2.
New Contract Capacity Change Requests will be added to the Connection Queue once either a preliminary or full study has been completed at which time they will be considered to have met the requirements to complete Gate 2.
Connection Queue Business Practices
The Connection Queue business practices outline the maximum timeframe expected to complete gate requirements for each stage of the Connection Process.
The primary objectives of the business practices are to ensure:
efficient progression of projects;
fair and non-discriminatory treatment of market participants;
fair and efficient management of AESO and TFO work resources; and
fair assignment of connection remedial action schemes in constrained areas.
The business practices also outline the resulting outcomes for meeting or not meeting the gate requirements outlined. In addition, other considerations have been included as these may affect the outcomes for meeting or not meeting the gate requirements outlined within the maximum timeframe expected, including the circumstances under which the AESO may grant extensions. In most cases, failure to complete gate requirements within the maximum timeframe will result in project cancellation.
Connection Remedial Action Schemes (RAS)
In circumstances where the AESO determines a project will cause or materially contribute to a transmission system constraint, the AESO will assign and utilize RAS based on the order projects are listed in the Connection Queue. As noted above, projects are listed in the Connection Queue based on the date of Gate 2 completion. Therefore the assignment of RAS priority is based on the date of Gate 2 completion.
The AESO has begun the process of developing an ISO Rule and Information Document specific to Connection Remedial Action Schemes. This documentation further outlines the protocol specific to the use of RAS for early connection of projects in advance of when the system is capable of handling the full output or load associated with the project.
