Listed below is the summary description of changes for the proposed new, removed or amended sections of the ISO rules. Please refer back to the Letter of Notice under the “Attachments to Letter
of Notice” section to view the actual proposed content changes to the ISO rules. Please place your comments / reasons for position underneath (if any).
1. ISO Rules
New
Proposed New ISO Rules Section 304.4 Version 2.0 sets out requirements
regarding adjustments to the set point of the automatic voltage regulator or
voltage regulating system or the on-load tap changer, and indicates exceptions.
The AESO is proposing the following amendments in Version 2.0:
1. Subsection 1 has been amended such that it is applicable to an operator of a
transmission facility operating a “controllable reactive power resource” rather
than a “synchronous condenser”.
In the AESO’s opinion, “controllable reactive power resource” is broader and
a more appropriate term to use in the context of “maintaining network
voltage”.
2.
Subsection 2 has been amended to allow for adjustments to the set point of
the automatic voltage regulator or voltage regulating system, the on-load tap
changer; or the set point or status of the controllable reactive power resource
after advising the AESO and receiving approval. In the AESO’s opinion, this
language more closely reflects the intent of ISO OPP 702 Voltage Control.

Stakeholder Comments and/or Alternative Proposal
Comment # 1:
AESO Replies
ENMAX Power Corporation (“EPC”) appreciates
the opportunity to comment on proposed ISO Rule,
Section 304.4 Version 2.0.
The current version of the proposed rule makes
no exception for emergency situations where immediate
action without the ISO’s pre-approval would be required
in order to protect personnel, the public’s safety and/or
prevent significant damage to equipment. The inclusion
of such a provision would be prudent and consistent
with the Section 39(4) of the Electric Utilities Act.
EPC understands that ATCO Power has
already suggested that the AESO include a provision for
emergency situations. The AESO’s reply however, only
addresses ATCO’s concern in the context of a system
restoration event which may not encompass all
emergency situations.

The AESO is seeking comments from stakeholders with regard to the following
matters:
1. Are there any subsections where stakeholders feel that language does not
clearly articulate the requirement for either the AESO or a market participant?
If yes, please indicate the subsections and suggest language that would
improve the clarity.
Other
Stakeholders wishing to comment on specific provisions are requested to copy
the provision into this area and provide comments.
