Applicability
This reliability standard applies to:
(a) the legal owner of a transmission facility that is:
(i) part of the bulk electric system; or
(ii) not part of the bulk electric system and which the ISO:
(A) determines is necessary for the reliable operation of either the interconnected electric system
or the City of Medicine Hat electric system, and
(B) publishes on the AESO website and may amend from time to time in accordance with the process
set out in Appendix 1;
(b) the legal owner of a generating unit that is:
(i) directly connected to the bulk electric system and has a maximum authorized real power rating
greater than eighteen (18) MW;
(ii) within a power plant which:
(A) is not part of an aggregated generating facility;
(B) is directly connected to the bulk electric system; and
(C) has a combined maximum authorized real power rating greater than sixty-seven point five
(67.5) MW;
(iii) a blackstart resource; or
(iv) regardless of maximum authorized real power rating, material to this reliability standard and to the
reliability of the bulk electric system as the ISO determines and publishes on the AESO website and
may amend from time to time in accordance with the process set out in Appendix 1;
(c) the legal owner of an aggregated generating facility that is:
(i) directly connected to the bulk electric system and has a maximum authorized real power rating

General Notes
The AESO developed this Alberta Reliability Standard Audit Worksheet (RSAW) to add clarity and
consistency to the audit team’s assessment of compliance with this reliability standard, including the approach
elected to assess requirements.
Additionally, the RSAW provides a non-exclusive list of examples of the types of evidence a market
participant may produce or may be asked to produce to demonstrate compliance with the Alberta Reliability
Standard. A market participant’s adherence to the examples contained within this RSAW does not constitute
compliance with the applicable Alberta Reliability Standard.
This document is not an AESO authoritative document and revisions to it may be made from time to time by
the AESO. Market participants are notified of revisions through the stakeholder update process.
