Introduction and Purpose
The AESO 2023 Reliability Requirements Roadmap (R3) defines three key areas of reliability — Frequency Stability, System Strength and Flexibility Capability — and includes descriptions of each issue, the degree of mitigation urgency, key findings from reliability assessments, and action plans. Implementation of action plans defined in the 2023 R3 is ongoing, and work has been initiated on the 2025 edition of the R3, which the AESO expects to publish in March 2025.

Purpose
The AESO is conducting a survey on considerations related to the Rate of Change of Frequency (RoCoF) as part of the planned actions outlined in the 2023 Reliability Requirements Roadmap (2023 R3). Our goal is to assess the equipment limitations, protection settings and risks associated with RoCoF during system-wide frequency events. The participation of existing generation facility owners (GFOs) is vital for us to accurately define these risks. We also welcome feedback from project developers, Original Equipment Manufacturers (OEMs), and consultants. The survey is open from December 11, 2024, through February 28, 2025. We thank you in advance for your participation.
