Transmission Capability and Utilization

Consultation has concluded

Key Dates

Sept. 22, 2023 | Transmission Utilization Presentation, Map and Report posted

Purpose

The need for a Transmission Capability Assessment was identified as a business need to provide locational signals to Market Participants.

This resulted in a need to carry out transmission capability assessment in order to provide:

Granular locational signals:

  • Inform market participants of where capability is available
  • Assess capability for accommodating individual connection projects
  • Help streamline connection process stages, alternative selection and project change proposals

Enhanced methodology:

  • Assess capability of substations
  • Inform need for development of transmission plans

The purpose of the Transmission Capability an Utilization engagement is to develop a probabilistic capability assessment methodology and carry out a substation capability assessment map to be shared with external market participants.

Out-of-scope for the engagement

The following topics are out-of-scope and will not be discussed as part of the Transmission Capability Assessment information session:

  • Project-specific questions
  • Changes to the regulatory framework (e.g., TReg, TPL standards)
  • 2018 GTA Decision and Corresponding Compliance Filing Items
  • Existing System and Connection projects

  • Information Session 2 | April 20, 2022

    CLOSED: This session has concluded.

    Purpose

    The purpose of this session was to build on the information provided to stakeholders at the Transmission Capability and Utilization session on Nov. 23, 2021. The session reviewed the assumptions and methodologies used in the development of the AESO’s transmission capability mapping tool as well as its vision, intended use and timing of updates. This included a walk-through of the map, a facilitated Q&A to respond to stakeholder questions, and details around supporting user experience. The session also provided stakeholders with an overview of additional supports the AESO will be implementing related to System Access Service Request (SASR) submissions.

  • Information Session 1 | Nov. 23, 2021

    CLOSED: This session has concluded.

    Purpose

    • Stakeholder session to provide awareness and understanding of the AESO’s assumptions and methodologies used in development of the transmission capacity map
    • Provide stakeholders with an introduction to transmission utilization, including the fundamentals of transmission planning for contingencies, and a preliminary discussion on appropriate utilization metrics to use for transmission utilization.
