Purpose

The purpose of the AESO 2025 Reliability Requirements Roadmap (2025 Roadmap) is to identify reliability requirements to sustain and improve the operational reliability of Alberta's electric system. The 2025 Roadmap sets out plans addressing three critical areas—System Strength and Stability, Flexibility and Balancing, and Frequency Response and Stability. The AESO has made significant progress since the publication of the 2023 Reliability Requirements Roadmap in several areas critical to ensuring operational reliability, which are outlined in the 2025 Roadmap. An update is provided on the decisive action we're taking to address growing reliability challenges, ensuring the grid remains reliable and capable of supporting the evolving energy landscape.

The 2025 AESO Reliability Requirements Roadmap is aligned with the Restructured Energy Market (REM) and highlights new priorities and action plans.

  • IBR Connection Requirements Information Session | February 28, 2024

    CLOSED: This discussion has concluded.

    Purpose

    The AESO hosted a virtual Stakeholder session on February 28, 2024, to discuss new connection requirements for Inverter-Based Resources (IBRs.)

    Background

    The AESO’s Reliability Requirements Roadmap identified system strength as a key risk to reliability. During the Grid Reliability session in November 2023, the AESO discussed operational experiences that have reinforced the need for action on reliability issues caused by low system strength. One of the ways the AESO intends to improve reliability in relation to system strength is by introducing new connection requirements for IBRs.

    This session informed IBR owners of the new connection requirements, and project owners
