Dear Market Participants and Other Interested Parties:
Re:
Letter of Notice – Consultation on the Proposed Removal of ISO OPP 523 Medicine Hat Area
Operation (“ISO OPP 523 Removal”).
Pursuant to Section 2 of the Alberta Utilities Commission (“AUC”) Rule 017, the Alberta Electric System
Operator (“AESO”) is providing notice and seeking feedback from market participants and other interested
parties on the attached proposed ISO OPP 523 Removal.
Applicability
The proposed ISO OPP 523 Removal applies to:
(a) market participants;
(b) legal owners and operators of transmission facilities;
(c) the City of Medicine Hat Electric Utility Operator; and
(d) the AESO.
Background
Existing ISO OPP 523 Medicine Hat Area Operation (“ISO OPP 523”) sets out the policies and procedures for
managing the inflow to the City of Medicine Hat. In accordance with the principles of the AESO’s Transition of
Authoritative Document project, the AESO is proposing to remove ISO OPP 523 in its entirety to eliminate
duplication of authoritative requirements and unneccesary non-authoritative content.
Confidential Figures and Tables in ISO OPP 523
ISO OPP 523 contains confidential Figure 1, Medicine Hat Area Transmission System, Table 1, City of
Medicine Generators, and Table 2, City of Medicine DTS and STS Contract. As a result, when the AESO files
ISO OPP 523 Removal it will request that disclosure of Figure 1, Medicine Hat Area Transmission System,
Table 1, City of Medicine Generators, and Table 2, City of Medicine DTS and STS Contract contained in ISO
OPP 523, would not be in the public interest.
Scope of Consultation
The scope of this consultation is limited to the proposed ISO OPP 523 Removal. Any comments received by
the AESO that are outside of the scope outlined above will not be considered by the AESO.
Previous AESO Consultations, Papers and Other Related Communications
No previous consultation has occurred specific to the proposed ISO OPP 523 Removal.
Request for Stakeholder Comments
Please use the attached comment matrix when submitting comments to the AESO on the proposed ISO OPP
523 Removal. The AESO’s rationale for the proposed ISO OPP 523 Removal has been provided in the
